FOR IR SENSORS:
• The output of the IR sensors can be disrupted by sudden changes in temperature. If there
is an excessive change in the ambient temperatures, gas sample temperature or flow rate,
then the output signal will be momentarily frozen. Correct operation is restored when the
effects of the transient have settled. Rates of change in the ambient temperature should be
restricted to 2 °C/minute and gas flow rates kept below 0.6 L/minute.
• Extreme pressure variations will cause errors in readings. The unit should be recalibrated
if the atmospheric pressure change is greater than 10% from the original pressure.
• Do not expose the sensor to corrosive gases such as Hydrogen Sulphide.
• Do not allow condensation to occur inside the sensor.
• Infrared combustible sensors are not CSA approved.
CALIBRATION ALERT:
Gas detection instruments are potential life-saving devices.
Recognizing this fact, calibration for the toxic and catalytic LEL sensors should be at
least at quarterly intervals, while the infrared sensor should be calibrated on an
annual basis with function test every 6 months.
Further, TELEDYNE OLDHAM SIMTRONICS recommends prudent testing and/or
includes calibration after a gas alarm. All calibration service to sensors should be
recorded and accessible.
CAUTION:
For safety reasons, this equipment must be operated and serviced by
qualified personnel only.
