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.

Accuracy, Precision, Resolution, and Sensitivity

This will dictate how the sensor responds. For example, take a sensor that is rated for 1000 units with an output voltage of 0-1 volts (V). This means that at 1 volt the equivalent measurement is 1000 units or 1 mV equals one unit. However the sensitivity is mV p-p so it will take two units before the input detects a change. The Measurement Computing USB-1608G Series Example Let’s use ...
