**EX-5150-MOS — Sensor/Transmitter for PPM Hydrocarbons & Organic Solvents**

A MOS sensor consists of a heated mixed metal oxide element that decreases in resistance in the presence of many gases and vapors. 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 toxic gases, including NH₃, CO, H₂S, etc. MOS sensors operate at a lower temperature 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. Silicones, which are used in a wide range of oils, lubricants, adhesives and many other products can poison hot wire sensors and also influence the performance of MOS sensors under certain conditions. Applications for monitoring of hydrogen and hydrocarbon gases where silicones are present in the environment should be discussed with ENMET.

EX-5150-MOS — Sensor/Transmitter for PPM Hydrocarbons & Organic Solvents

A MOS sensor consists of a heated mixed metal oxide element that decreases in resistance in the presence of many gases and vapors. 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 toxic gases, including NH₃, CO, H₂S, etc.
MOS sensors operate at a lower temperature 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. Silicones, which are used in a wide range of oils, lubricants, adhesives and many other products can poison hot wire sensors and also influence the performance of MOS sensors under certain conditions. Applications for monitoring of hydrogen and hydrocarbon gases where silicones are present in the environment should be discussed with ENMET.
