How to Select a Flame Detector - Scene7

UV/IR Flame Detectors When an optical UV sensor is integrated along with an IR sensor into a single instrument, a dual band detector is created that is sensitive to the UV and IR radiation emitted by a flame. The combined UV/IR flame detector offers increased immunity over either sensor type alone, and offers moderate speeds of response. UV/IR flame detectors are well suited for both indoor ...

What kinds of sensors are used to detect LEL combustible gas?

15/01/2019· IR LEL sensors used in portable CS instruments are not usually designed to detect acetylene. Depending on the manufacturer, they may or may not be able to detect benzene or other “unsaturated” volatile organic chemical (VOC) vapors. It is important to verify that the IR LEL sensor is able to detect the gas(es) of interest before use.

Difference between analog sensor and digital sensor

This type of sensor generates output in binary digital form consisting of binary 1s and 0s. This means digital sensor produces non-continuous or discrete form of signal. The figure-2 depicts digital sensor operation. Example of digital sensor: Digital Light sensor which uses rotating disc to generate output pulse with logic 0 and logic 1. These ...

Complete Gas Sensor Circuit Using Nondispersive Infrared ...

If IR light is applied to a dual thermopile detector fitted with a pair of optical filters so that one filter is centered on 4260 nm and the other on 3910 nm, the concentration of carbon dioxide can be measured from the ratios of the two thermopile voltages. The optical filter that resides within the absorption channel serves as the detection channel and the optical filter that resides outside ...

Radar sensors | Baumer USA

The radar sensor is also available in a configuration, where it operates similar to a light barrier. Via a special teach-in-algorithm the sensor learns the reflector position. After teaching the sensor monitors the reflector position. If an object breaks the line of sight between the sensor and reflector, the sensor output switches. The advantage of this configuration is that it is unnecessary ...
