GAS SENSING MODULE
Plug-in gas sensing module with signal conditioning. Precalibrated and standardised output signal.
Measuring Range:
0 to 5% v/v CH
4
. Calibrated for Methane
Alternative sensing ranges available to specification
Linearity:
±1% 0 to 60% FULL SCALE
±5% from 60% up to 100% FULL SCALE
Maximum Drift @ 25°C:
±0.25% v/v per month
Response Time (T90):
<20 secs
Sensing Element Life:
>5 years in clean atmosphere
Warm Up Time:
<5 mins in air or 1% v/v CH
4
. (To 95% of stated accuracy)
Calibration:
Digitally controlled ZERO and SPAN. Pushbutton setting
Signal Fix:
The transmitted output signal of the sensor is FIXED at 00.0 during calibration
to prevent false alarms from being initiated
Overrange:
If the measured gas concentration exceeds the calibration range of the sensor:
The STATUS indicator will flash
The display value will be CLAMPED
The transmitted output signal will be CLAMPED
Pellistor Protection:
The supply to the gas sensing element will be switched off to prevent
oxidisation damage occurring if the gas concentration exceeds safe limits.
The sensor will attempt to switch back on at 5 minute intervals until the
gas concentration has reduced to a safe level
