EX-5150 MOS (Metal Oxide Semiconductor) Hydrocarbon Detection

Sensor/Transmitter for % LEL or PPM Hydrocarbons and Organic Solvents

The EX-5150-MOS utilizes an MOS sensor. These sensors are broad range in their response characteristics. Different types of MOS sensors are available which can be optimized for a particular gas, but they are inherently non-specific.

The MOS sensor can provide monitoring capability similar to that of the classic catalytic bead or hot-wire sensor, but it can be calibrated for either % LEL or ppm detection levels of a wide range of hydrocarbons and organic solvents. The MOS sensor can also be used for detecting certain common inorganic toxic gases, including Ammonia (NH3), Carbon monoxide (CO), Hydrogen sulfide (H2S), etc.

MOS sensors operate at lower temperatures than catalytic bead/hot-wire sensors, which makes them less prone to poisoning. The MOS sensor is therefore the sensor of choice in applications where, for example, lead, phosphates or sulfur-containing compounds are present.
