Detector Parameters
NOTE
Performance figures are based on the following:
• Extended operating temperature range of −40 °C to +65 °C (−40 °F to
+149 °F) for all sensors except for H
2
EC sensors, with an accuracy of
±30% of applied gas from −20 °C to −40 °C (−4 °F to −40 °F) and +50 °C
to +65 °C (+131 °F to +149 °F). Long term continuous operation in the
extended temperature range may cause degradation in sensor
performance.
• Temperature range of over −20 °C to +50 °C. Oxygen versions is ±0.9%
vol. The accuracy of the flammable (CAT) versions is ±5%LEL.
• Operating temperature range of −20 °C to 50 °C for all sensors with an
accuracy of ±20% of applied gas.
• The humidity of the test gas is 50% RH. The performance values given
are valid between 10% and 90% RH.
• For H
2
S versions, accuracy degradation may be experienced in high
humidity environments. Recalibrate the unit in the environment in
which it is going to be used.
• Measured test units calibrated at 50% of full scale
• Measurements are based on gas being applied using the calibration
adapter at a rate of 500 ml/min for a period of 5 minutes (oxygen,
flammable [CAT], carbon monoxide, hydrogen sulfide), 6 minutes
(hydrogen), and 10 minutes (nitrogen dioxide )
• Response time (T90) may increase when operating in lower temperature
conditions.
• For H
2
version, recommend to recalibrate when using in low
temperature environments (< −10 °C).
Sensepoint XRL’s Canadian flammable gas performance approval
(CSA C22.2 No.152)
Sensepoint XRL’s flammable sensor was evaluated for CSA C22.2
No.152-M1984 (R2016). The evaluation is valid only with the
calibration flow rate 500 cc/min, CH
4
gas, catalytic bead sensor and
4–20 mA output. In terms of 4–20 mA, a 250
Ω
load resistor was
attached for the evaluation.
If Sensepoint XRL’s flammable sensor is suspected to be damaged by
aggressive substances, please perform bump test and calibration per
this manual.
