FCX-MC05: New high-resolution oxygen sensor module
Pewatron has released a new oxygen sensor module that can be used in many different applications and in several configurations. The key element of the sensor module is the oxygen sensor from Fujikura; it is an amperometric solid-state sensor with a high current output, a short response time to gas concentration changes and ruggedness against pressure change, humidity and other gases. Because of the high output current of the sensor, applications ranging from low ppm concentrations and up to normal air (and above) concentrations can be covered with one sensor only.
The FCX-MC05 sensor module is a signal-conditioning unit that gives the user the option of different sensor output modes, such as analogous linearised current output (0/4-20 mA), analogous linearised voltage output (0-10V) or a digital output using the RS485 or RS232 communication protocol. As the total power consumption is low (< 3W), the FCX-MC oxygen sensor module is suitable for mobile applications.
The oxygen sensor is configured either in a flow configuration with connectors for hosing or in a diffusion configuration. In the flow configuration, the sensor encapsulation is an aluminium flow housing, enabling analysis of oxygen concentrations from small sample extracts. The sensor can be placed on the sensor module PCB board for easy integration into transmitters or connected to the sensor module PCB board via cables in either configuration. The FCX-MC05 module supports cable lengths of up to 10 metres.
