How does a gas detector work? | Martek Marine

Any gas which can be oxidized or reduced electrochemically can be detected by means of a fuel based electrochemical sensor. The consumption of oxygen produces a current (µA) which is linearly proportional to the concentration of gas in air. Since the oxygen sensor is constantly exposed to oxygen, the normal life of the sensor is between 1-2years.

How Gas Detectors Work - Thomasnet

· As detectors measure a specified gas concentration, the sensor response serves as the reference point or scale. When the sensor's response surpasses a certain pre-set level, an alarm will activate to warn the user. There are various types of detectors available and the majority serve the same function: to monitor and warn of a dangerous gas level. However, when considering what type of ...

New Sensors for Ammonia Gas Detection - International Gas ...

· The Challenge for Ammonia Gas Detection. Ammonia gas is classed as a toxic gas under COSHH regulations and therefore you will require an ammonia gas detection system to monitor the atmosphere to comply with COSHH. However, one of the main downfalls of current ammonia gas sensors is that they don’t really fit the bill, especially for refrigeration plants.
