Shallow Water Micro-sensor for Dissolved Oxygen For very fast vertical and horizontal profiling The galvanic dissolved oxygen micro-sensor for shallow water has been developed above all for the very fast in-situ depth profiling with CTD probes and for horizontal profiling with towed unduclating vehicles, ROVs or AUVs in rivers, lakes and oceans. Because of the partial pressure of the gaseous O2 , the analyte permeates through the membrane. Inside of the sensor the oxygen reacts electrochemically at the working electrode. This causes a current corresponding to the partial pressure of the dissolved oxygen.  The sensor has a very short response time of down to some hundred milliseconds for t90% . Streaming, as it is well-known from all the other Clark-type membrane covered oxygen sensors, is not necessary. Therefore profiling with very high local resolution is possible. Both turbid, muddy and coloured solutions do not affect the sensor signal.  For measuring the oxygen saturation, the sensor has to be combined with a temperature measurement. If the oxygen concentration has to be determined, the additional measurement or knowledge of the conductivity/salinity is required. The maximum deployment depth is 100 m. All sensors are delivered with temperature compensation data.    ...read more

Hydraulic Mining In hydraulic mining, very powerful jets of water are used to loosen the gems from the rocks. A large pan is filled with water and then it is shaken back and forth to ensure the heavy materials fall to the bottom of the pan; this is repeated until there is a small amount of concentrate left in the pan. Then a plastic tube is passed through the hole, water is then pushed through this tube at very high speeds. More tunnels are made for blasting the rocks and the gems are found from amongst the rocks. Due to its harmful effects on the natural environment, this type of mining is not used now. This is the most common way of finding gemstones, and involves miners digging underground until they find gemstones. creek or stream; an obvious pre requisite of this is identifying the gravel which could possibly contain the rubies. The water splits the rocks and washes large pieces downhill; this causes the gems to be separated. Shaft Mining Vertical tunnels called shafts are created below the mountain when shaft mining is used. Once you have the raw gemstone, it can be cleaned, cut and polished to produce the finished article. Dynamite is then used to blast the top of the mountain; the resulting large rocks are then scoured for the gemstones. The opening s created are called tunnels, and the gemstones are derived from the materials that come through the tunnels down from the hills. Underground Mining This method of mining is used as an alternative to surface mining, which is often not possible. Mountaintop Removal Mining This method entails cleaning the mountaintop at the ground level by cutting down trees and shrubs. This water breaks the rocks and forms muddy slurry, which is stored in tankers. There are other methods which we will also briefly touch upon. Miners moveSwing Clampup and down one of the shafts and another shaft is used for bringing the material from below the ground. The main forms of underground mining are: Borehole Mining Holes are drilled very deep inside the land using very large bore drills. These rocks are then processed to extract the gemstones. The water is then separated from the slurry to leave gemstones. . Drift Mining Drift mining is performed on the mountains and entails first identifying rocks which are below the side of the mountain. Placer Method of Mining The placer method is also known as river panning and involves collecting the gemstones whilst washing away gravel from a river. Then this concentrate is moved to a smaller pan to see if there are any gems. Summary In most of the mining methods we have discussed, rocks are broken down into small or medium chunks using explosives such as dynamite. The main methods of mining rubies are placer, underground mining and hydraulic mining; the method depends on how deep into the earth the rubies are situated.In todays article, we will give you a short introduction on how rubies are mined and the process involved ...read more

Plastic Injection Molding is a kind of tool used to produce hundreds of or thousands of plastic parts. Most of our daily used plastic parts are made byplastic injection molding. Mould design and making is the most important process among the courses of injection molding. Generally speaking, the mould comprises of two main components, the injection mould and ejector mould, or named A plate and B plate.(Some complex parts would require three plate mould by adding a gate plate.) A plate is fixed on the stationary platen of the injection molding machine or press connected with the nozzle,while B plate is mounted on the rear platen. The molten plastic is injected into the cavity of the mold through the sprue bush. After the cavity is full of the molten plastic, the cooling system works to shape the parts, and then the B plate moves backward to eject the molded parts out. The basic elements of the mould includes Sprue bush, Locating ring, Runner, Gate, Fixed halve and moving half, Core and cavity, Ejector pins, Return pins, Sprue puller, Ejector Plate / rod, Cooling channels, Guide pins, Locating plugs, Back plate, Spacers. The job of mould designer is to choose the proper systems and mechanism according to the parts. Material impacts the mould design and making Various plastic materials have different flow rate and shrinkage rate and some special propertities. The design engineers have to creat the lager cavity than the final parts. The spared space can be calculate by the CAD software. Some defects would happen if the engineers made the mistakes in this stage. The experience of the engineers would largely benefit the process when we take the some real conditions into consideration. The cost of building the tool for different plastic also varies largely. For example, the cost toilet seat mould for Urea-formaldehyde is double of Polypropylene. Geometry impacts the mould design and making Manufacturing high quality injection molded parts needs 3 balances, the balance of flow, the balance of heat and the balance of freezing. Engineers have to position the gate to make sure the proper melt flow and pressure according to the geometry of the parts. The gates can not be placed on the conspicuous location. The runner system and cooling system also need to be designed appropriately. The slide system will be utilized when the parts have undercuts. Generally the parts with wall thickness lower 0.5mm and higher than 5mm are not suitable for plastic injection molding. Finish impacts the mould design and making Sometimes, the clients want some special texture finish or high glossy finish. Design engineers need to change some indexes to accommodate the finishes. Parting line has to be made as invisible as possible or placed on a inconspicuous position. The texture is created by chemical errosion. Mould designers should decide the depth of the texture. Actually there are some other things affected the mould design and making, like the precision of the EDM machines, the skill of the workers and the experience in the specific industry. Jingwei molding has more than 15 years experience in mould design and making. Any questions,please feel free to contact us via info@jweimolding.com ...read more

The world's fastest battery-powered NDIR CO2 sensor Gas Sensing Solutions (GSS) Ltd, the LED-based NDIR detector specialists, continues to push the boundaries for CO2 detectors with the launch of its new SprintIR6S.  GSS' unique SmartIR™technology has enabled it to create a sensor that can take up to 20 readings per second, which is a world record for NDIR CO2 detectors, and has a six times faster response rate than the SprintIR CO2 sensor*. Ralph Weir, GSS' CEO, explained, "We are the only company producing CO2 sensors using LEDs and photodiodes and, as we make the LEDs and photodiodes ourselves, we have been able to develop ultra-fast response times that no otherNDIR sensorcan match.  Typical NDIR CO2 detectors take several seconds or even minutes to take a reading - because they use slow-reacting IR sources, which need time and energy to warm up, like MEMS hotplates, micro-bulbs or filament-based micro-lamp technologies. Our LEDs, by contrast, are Solid State emitters, and illuminate almost instantly.  With the new SprintIR6S, we've also minimized the sample volume down to only 2ml, which enables us to achieve our fastest ever response rates*.  This puts us in a unique position to open whole new application areas for CO2 monitors that could never be addressed by slow responding sensors based on traditional IR sources.&quot; Applications for this new class of ultra fast CO2 sensors include health where they can capture rapidly changing CO2 concentrations in the breathing cycle to provide diagnostic information, which can be used in fitness testing, breath analysis/measurement, capnography, sports science and veterinary to name a few.  In Industrial Health and Safety applications, such as factories where CO2 is used for modified atmospheres to delay packaged food from spoiling, they can provide ultra fast detection of rising CO2 levels.  Even a doubling or tripling of normal CO2 levels can affect concentration and productivity with higher levels having increasingly deleterious effects on health right up to unconsciousness and death.   &quot;A leak from a CO2 canister or similar can push CO2 levels up from the normal 400ppm to several thousand ppm in seconds,&quot; added Ralph Weir.  &quot;You cannot smell CO2 and it is colorless.  Yet it can present serious health problems at raised concentrations so, the sooner an alarm is raised, the sooner people can take remedial action.  For example, restaurants and pubs usually have CO2 cylinders in the basement for the drinks but basements typically have poor ventilation so an undetected CO2 leak could suddenly raise the CO2 level when someone was in the basement and render them unconscious - or dead.  Our new sensors can give the earliest possible warning.&quot;  GSS' multi-patented SmartIR™ technology detects the presence of CO2 by detecting how much light is absorbed by CO2 molecules as light passes through the sample gases - called Non-Dispersive InfraRed (NDIR) absorption.  CO2 absorbs between 4.2 and 4.4 microns so that its presence is easily detected, and the amount of light absorbed indicates how much CO2 is present. Typically, CO2 detectors use a miniature heater (such as MEMS devices like micro hotplates, microlamp/microbulb or filament heater) to generate a range of wavelengths that have to be filtered down to the wavelengths needed, which is wasteful and energy inefficient, especially as a lot of heat is produced.  By contrast, GSS developed the world's first commercial, mid-range IR LEDs that are specifically tuned to emit just at 4.2 to 4.4 microns, making them highly energy efficient.  As a result, GSS CO2 sensors are the onlyNDIR CO2 sensorsthat can be powered by batteries - a single lithium cell can power a SmartIR sensor for up to ten years. At less than a cubic inch (23.8mm in diameter and 24mm tall), the SprintIR6S operates at between 3.25 and 5.5V, with a power consumption of only 35mW.  The SprintIR6S is available in measurement ranges from 0%to 100%. GSS will be revealing the new SprintIR6S detectors at the Sensor + Test show in Nuremberg, Germany from 30 May to 1 June 2017. High Speed Carbon Dioxide SensorNDIR CO2 SensorSprintIR SummarySprintIR is a high speed (20 Hz)CO2 sensor, ideally suited for applications which require capture of rapidly changing CO2 concentrations including metabolic assessment and analytical instrumentation. Fast, Accurate Carbon Dioxide SensorThe SprintIR carbon dioxide sensor is the fastest, most accurate CO2 sensor on the market. A breakthrough in NDIR technology, the SprintIR uses advanced solid state Indium Antimonide LED’s and detectors to offer a robust sensor with no moving parts, no heated filaments, and incredibly low power requirements. The sensor comes in four versions - from 0% to 100% - all capable of the same high-speed CO2 measurement.

GUVA-S12SD UV Sensor TheGUVA-S12SDUV Sensorchip is suitable for detecting the UV radiation in sunlight. It can be used in any application where you want monitor for the amount of UV light and is simple to connect to any microcontroller. I recently noticed that some sellers had little modules for this sensor at a reasonable price so decided to purchase one The module, with a typical UV detection wavelength of 200 – 370nm, outputs a calibrated analog voltage which varies with the UV light intensity so basically all you need to do is connect this to an ADC input and read in the value. This value ties in with the UV index, this looks something like this Connection The connections are straightforward and described below, I used 3.3v from my Arduino. This was mainly for compatibility with other development boards but the module works with 5v. 1. GND: 0V (Ground)2. VCC: 3.3V to 5.5V3. OUT: 0V to 1V ( 0 to 10 UV Index) Layout As said its a simple layout but here you go Code Simple code example that reads the value at A0 and outputs the results via the serial monitor, if you use 5v rather than 3.3v then you will need to change the 3.3 in the following line sensorVoltage = sensorValue/1024*3.3; Source code void setup() { Serial.begin(9600); }   void loop() { float sensorVoltage; float sensorValue;   sensorValue = analogRead(A0); sensorVoltage = sensorValue/1024*3.3; Serial.print("sensor reading = "); Serial.print(sensorValue); Serial.println(""); Serial.print("sensor voltage = "); Serial.print(sensorVoltage); Serial.println(" V"); delay(1000); } Testing Open the serial monitor and look at the readings sensor reading = 46.00sensor voltage = 0.15 Vsensor reading = 46.00sensor voltage = 0.15 Vsensor reading = 46.00sensor voltage = 0.15 Vsensor reading = 46.00sensor voltage = 0.15 Vsensor reading = 46.00sensor voltage = 0.15 V If you look at the image earlier that corresponds to UV index of 0 which is a relief because I tested this indoors UV-A Sensor - GUVA-S12SD Product Specification 1.Features Gallium Nitride Based Material Schottky-type Photodiode Photovoltaic Mode Operation Good Visible Blindness High Responsivity & Low Dark Current 2.Applications UV Index Monitoring UV-A Lamp Monitoring 3.Outline Diagrams and Dimensions 4.Details ...read more

CO2 Sensor Occupancy Detection A group of researchers at the University of California in Berkley have designed an algorithm that can count the number of people in a room when only the CO2 level is known. The study, titled “Sensing by Proxy: Occupancy Detection Based on Indoor CO2 Concentration” used SenseAir’s K-30 carbon dioxide sensor module for occupancy detection. The "Sensing by Proxy" model is more accurate than previously used machine learning models, and could be used to improve the efficiency of Demand-Controlled Ventilation systems (DCV) currently in use. DCV works on the principle that you can save energy by heating, cooling or adding fresh air to a room only when it is needed. While heating and cooling can be controlled with a thermostat, the amount of fresh air that should be added to a room can be controlled by a carbon dioxide level transmitter. When CO2 levels go up, fresh air is added until the CO2 levels return to normal (typically 10% or less of the background CO2 levels). WhileCO2 transmittersin a DCV system are good at monitoring CO2 levels, they do not tell you the number of occupants in a room. This is important because indoor air quality models specify the optimum fresh air exchange rate per person. If you don’t know how many people are in a room, all the system can do is pump in fresh air until the CO2 level drops. This is where Sensing by Proxy comes in. Using the K-30 sensor’s CO2 level data as the only input, the researchers were able to create a model “that captures the spatial and temporal features of the system and links unobserved human emission to proxy measurements of CO2 concentrations.” The algorithm they developed was tested in both controlled and field experiments, and resulted in an error rate of 0.6 fractional persons as compared to 1.2 fractional persons by the best alternative strategy. The algorithm is also better at measuring changes, such as occupants entering and leaving a meeting. In addition, it does not require more costly Pyroelectric infrared (PIR) or Ultrasonic sensors used for current occupancy detection systems. The algorithm is one of a growing number of papers that test the use of CO2 levels for occupancy detection. For example, Chaoyang Jiang and others in a paper titled “Indoor occupancy estimation from carbon dioxide” were able to estimate occupancy in an office with 24 cubicles. They counted occupants accurately 94 percent of the time within a tolerance of four occupants. While DCV is initially more expensive to install, improvements like this could be used to further reduce the long-term energy costs in DCV controlled buildings.     ...read more
