MF010 Series Low Temperature and MF020 Series High Temperature Oxygen Sensors DESCRIPTION The MF010 Series Low Temperature Oxygen Sensors is designed to determine the oxygen concentration in air or inert gas mixtures with temperatures of -100 °C to 250 °C [-148 °F to 482 °F] max. The MF020 Series High Temperature Oxygen Sensors is designed to determine the oxygen concentration in air or inert gas mixtures with temperatures of -100 °C to 400 °C [-148 °F to 752 °F] max. These products are particularly suitable for measuring oxygen in areas that are not easily accessible, or in closed systems. The MF010 and MF020 Series may both be supplied with a measuring range of 0.1 vol%O2 to 25 vol%O2 and 0.1 vol%O2 to 100 vol%O2. The entire measurement range is linear for both series. The sensor detects the gas mixture’s oxygen partial pressure (absolute oxygen content) by using a dynamic process that occurs on two zirconium dioxide discs which form a hermetically sealed chamber. Because no chemical substances are used, the sensor exhibits significantly longer service life than an electrochemical sensor. The actual oxygen sensor is mounted in the tip of the bar probe and is protected by a stainless-steel sintered disk which serves as a flame back-flash stop. The water-proof plastic housing accommodates the electronics and is mechanically connected to the bar probe. FEATURES No moving parts Low power consumption No need for temperature stabilization Functional testing and calibration in ambient air Long life Sensor electronics include: 1. Signal amplifier 2. Control for the ionic pump with an analog component 3. Test component 4. Internal monitoring logic component 5. Power supply for the sensor heating element and the analog and digital components 6. Reset 7. Voltage monitor 8. Analog output 9. Bi-directional digital output 10. Internal potentiometer The sensor outputs the measured values via an analog channel (4 mA to 20 mA or 0 V to 10 V) and a digital channel (also provides any error signals) which are evaluated and further processed in a user-specified external mounting device such as a fuel controller, display, measuring instrument, programmable logic controller or ventilation system. Both series may be calibrated manually or self-calibrated using atmospheric air instead of a reference gas. The sensor can also conduct external operational self-tests. Both series may also operate in a fault-proof mode. The sensor self-monitors during operation and provides error signal output. A second oxygen sensor is not necessary.
