Metal-oxide(MOX) gas sensor elements
- Metal-oxide(MOX) gas sensor elements and arrays for the detection of:
- Carbon monoxide (CO), Hydrogen (H2)
- Nitrogen monoxide (NO), Nitrogen dioxide (NO2), Ozone (O3), Ammonia (NH3), Sulfur dioxide (SO2)
- Hydrocarbons (CXHY/ C1-C8), e.g. Methane (CH4), Propane (C3H8) etc.
- Alcoholes (CXHYOH), e.g. Ethanol (C2H5OH) etc., selected other Volatile Organic Compounds (VOCs), Refrigerants (R134a etc.) etc.
Types of gas sensors and detectable gases
- Our MOX gas sensor elements are realized in hybrid-technology: ceramic carrier substrate (Al2O3) with a micro-structured platinum thin-film layer, covered with a passivation layer + specific layers for contacts + gas-sensitive metal-oxide(MOX) layer/s. ...
- The functionality of a MOX gas sensor is based on the conductivity-change of the gas-sensitive MOX-semi conductor layer/s at gas exposure. ...
- Various sensor cases:
- Gas sensor elements in a TO39-case (socket with chip + specific T/2T-cap with filter):
- 4-Pin-case for single and multiple gas sensor elements
- 8-Pin-case for gas sensor arrays
- Single and multiple gas sensor elements in iso-thermic 4-Pin-SMD-cases
- Customized versions and solutions: e.g. sensor elements on specific carrier PCBs, specific sensor cases, sensor heads etc. (on request)
