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.
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.
