Gas Sensor By Unity Power Factor Controllers Pvt. Ltd.

Gas SensorGas sensors interact with a gas to initiate the measurement of its
concentration. The gas sensor then provides output to a gas instrument to
display the measurements. Common gases measured by gas sensors include ammonia,
aerosols, arsine, bromine, carbon dioxide, carbon monoxide, chlorine, chlorine
dioxide, Diborane, dust, fluorine, germane, halocarbons or refrigerants,
hydrocarbons, hydrogen, hydrogen chloride, hydrogen cyanide, hydrogen fluoride,
hydrogen selenide, hydrogen sulfide, mercury vapor, nitrogen dioxide, nitrogen
oxides, nitric oxide, organic solvents, oxygen, ozone, phosphine, silane, sulfur
dioxide, and water vapor.
Important measurement specifications to consider when looking for gas sensors
include the response time, the distance, and the flow rate. The response time is
the amount of time required from the initial contact with the gas to the sensors
processing of the signal. Distance is the maximum distance from the leak or gas
source that the sensor can detect gases. The flow rate is the necessary flow
rate of air or gas across the gas sensor to produce a signal.
