MF-Oxy-Comp
The oxygen sensor MF-Oxy-comp has been specially developed for use in composting plants. The materials used meet the high requirements of this field of application. The measurement method is based on a dynamic process at two zirconium dioxide slices, which form a hermetically sealed chamber. The entire measuring range is linear.
During operation the sensor system monitors its own function and reports in case of hardware and sensor malfunction.
The calibration is done without reference gas in atmospheric air. The output of the measurement values takes place via an analog (4 - 20 mA) and a digital channel, the latter transmits the error messages.
The oxygen sensor MF-Oxy-Comp is designed for the measuring range 0.1 to 25 vol% oxygen and equipped with an analog interface with 4 - 20 mA and has a digital output as well. The probe is designed so that it can check the operation during its proper functioning. For this +24 V DC is applied to the test pin. The test simulates a 20% lower oxygen concentration to the probe. This change must reflect equally in the analog channel. The device complies with the generic standards DIN EN 50270: 2015-5 type1 and type2 and DIN EN 61326-1: 2013-07 and so with the EMC-directives 2014/30/EU. The device is delivered already calibrated. The interval of the maintenance meets the safety requirements. The device can be calibrated on fresh air and is supporting an electric and a manual calibration. For the electrical calibration the test pin is set to +24 V DC. The probe then calibrates itself autonomously on fresh air within a tolerance range of 10%. Outside the tolerance range the sensor can be calibrated manually. Manual calibration is performed by means of a potentiometer within the housing.
