Thermal Conductivity Gas Sensors | SGX Sensortech

Thermal Conductivity Sensors. Because pellistors measure the flammability of a gas, they cannot be used to measure levels of gas above the Lower Explosive Limit (LEL), since the reducing level of oxygen will result in a fall-off of signal. However, a similar device can be used to monitor these high levels of gas, the themal conductivity pellistor.

NTC thermistor | Resistor types | Resistor Guide

NTC sensors are typically used in a range from −55°C to 200°C. The non-linearity of the relationship between resistance and temperature exhibited by NTC resistors posed a great challenge when using analog circuits to accurately measure temperature, but rapid development of digital circuits solved that problem enabling computation of precise ...

Thermal Conductivity Detector - an overview ...

Thermal Conductivity Detector. The TCD is a universal, nondestructive, concentration-sensitive detector that responds to the difference in thermal conductivity of the carrier gas and the carrier gas containing sample. It is generally used to detect permanent gases, light hydrocarbons, and compounds that respond poorly to the FID.

The 3 Types of Particle Detectors: How We See the Invisible

The detector is a chamber with an air current going through it. On one side of the chamber, there is an infrared emitter (like a light bulb), and on the other side, there is an infrared sensor. Each particle in the air blocks a little bit of light, meaning that a little bit less of it will reach the sensor. In other words, the light gets dimmer.

Infrared homing - Wikipedia

Infrared homing is a passive weapon guidance system which uses the infrared (IR) light emission from a target to track and follow it. Missiles which use infrared seeking are often referred to as "heat-seekers" since infrared is radiated strongly by hot bodies. Many objects such as people, vehicle engines and aircraft generate and emit heat and so are especially visible in the infrared ...

Indoor and outdoor air has between 400ppm and 2,000ppm CO2 by volume. This means that for projects from measuring indoor air quality to measuring atmospheric CO2, a 0-1% (0-10,000ppm) CO2 sensor is your best solution. For applications like CO2 alarms in restaurants, breweries, or around stored CO2 tanks, a 5% CO2 sensor is used.
