Robust design for demanding applications
Pewatron has released a new oxygen sensor module that can be used in demanding applications where oxygen concentrations below 1000 ppmO2 are measured. The key element of the sensor module is the oxygen sensor from Fujikura; it is an amperometric solid-state sensor (zirconia) with high output accuracy, a short response time to gas concentration changes and ruggedness against pressure change, humidity and other gases. The non-amplified signal from the oxygen sensor is in the range of micro amps and linear. The FCX-MP1000 sensor module is a signal-conditioning unit that amplify the sensor current output and gives an analogous, low-noise linearized current output (4-20 mA). As the total power consumption is low (< 2W), the FCX-MP1000 oxygen sensor module is suitable for mobile applications.
The oxygen sensor is configured in a flow configuration with connectors for hosing. The ppm sensor is encapsulated in a pressure proof aluminium flow housing, enabling analysis of oxygen concentrations from small sample extracts. The output oxygen concentration is highly linear and the accuracy is better than +/-50 ppmO2 with a response time for gas concentration changes of below 10 seconds. Concentration ranges are from 0 to 1000 ppmO2.
