Micro – Instruction Manual
The sensor is configured to provide a scaled analogue output in one of two voltages as
follows;
1. Scaled output of 0.5mV/%O
2,
equivalent to 0- 50mv for 0% to 100% oxygen –
Variants 01115704, 01115705, 01115710, 01115711 and 01115714.
2. Scaled output of 10mV/%O
2,
equivalent to 0- 1v for 0% to 100% – Variants
01115706, 01115707, 01115712, 01115713 and 01115715.
If the sensor is operated outside of its environmental specification the analogue output
will go to -15% O
2
(-0.15 volts for the 10mV/%0
2
range and -7.5mV for the 0.5mV/%0
2
range).
If the sensor detects an electrical or sensing element malfunction or the sensor is
exposed to extreme temperatures the analogue output will go to the supply rail voltage
(+5V dc ±5%).
4.4 Location of Sensor
The sensor body should be fixed rigidly to the OEM assembly and away from vibrating
components and, in particular, care should be taken to avoid mounting the sensor onto
a chassis or plate that may act as a lever or spring. If the OEM equipment is subjected
to excessive mechanical shocks and vibration during use, it may be necessary to
mount the sensor on shock absorbers to dampen the impact to the output of the
sensor.
The sensor should be protected from sudden temperature variations, such as from
cooling fans, as this can affect the sensor’s calibration. Fitting the sensor into a
temperature controlled environment will eliminate varying environmental conditions and
optimize its performance.
4.5 How to Minimise Exposure of Pneumatic System to Contaminants
Keep the components of the pneumatic system, whether in the laboratory or in the
production assembly area, away from the ‘dirty’ operations, such as drilling, packaging,
filing, cutting, deburring and finishing.
Assemble components in a clean environment and ensure all the components in the
sample line tubing have been cleaned for oxygen service and are bagged immediately
after cleaning.
4.6 How to Handle the Sensor
Carefully remove the sensor body from the anti-static packaging and only handle the
sensor using
anti-static handling procedures.
Do not remove the self-adhesive dust cover until the sensor is ready to be fitted in the
host equipment.
The sensor should be fitted into the OEM equipment under clean conditions in order to
minimise the likelihood of contaminants entering the sensor or the OEM system.
