FIS Semi-Conductor Gas Sensors

Envin Scientific (UK), announces the release of a range of electronic modules incorporating the leading FIS semi-conductor gas sensors. These electronic modules provide temperature compensated control and alarm outputs for a full range of gasses covering industrial, environmental, refrigerant and air quality applications. One of the difficulties in using semi-conductor sensors is their non-linear response and spread of characteristics, the modules remove these obstacles to give reliable and cost effective detection using industry standard outputs. System designers now have the freedom to use a common footprint module which can be replaced at service without the need to perform re-calibration. The modules come in 4-20mA, 1-10V linear analogue output versions with digital level alarm outputs and a relay version for switching applications. There is also a small form factor module providing a digital level alarm output for detection systems. The modules are pre-calibrated to customer requirements and use the full range of FIS semi-conductor sensors.
