NOTES
Performance figures are taken at 20~25°C;
1. measured using a sample humidity of 50 % RH, applicable between 10 and 90 % of full scale,
2. measured using test units calibrated at 50 % of full scale,
3. measured at 1000 cc/min for Methane CAT, 500 cc/min for O2, Toxic and Methane/Carbon Dioxide IR with calibration cup (S3KCAL).
4. Toxic and Oxygen sensor recovery times are taken at 20°C, 50 % RH and 500 cc/min with calibration cup (S3KCAL).
5. The maximum recommended alarm level for flammable sensors according to EN60079-29-1 is 60 % LEL.
6. Please note that XCD oxygen transmitter is intended for the measurement of oxygen deficiency or enrichment and not for inertisation measurements.
7. Response time (T90) under test conditions of EN 50104 ≤ 38 s
8. Response time (T90) under test conditions of EN 60079-29-1 for methane ≤ 55 s, for propane ≤ 60 s.
Response time (T90) may increase when operating in lower or higher temperature conditions or when gas is introduced with the Weather Protection accessory (SPXCDWP) fitted. Methane IR sensor is calibrated and linearized
only for Methane. Should it be exposed to other HC then non-linear response is expected. For linearized operation other than Methane contact Honeywell for alternate parts. Flammable CAT and Methane IR is calibrated at the
factory 50 % LEL Methane (2.5 % v/v). This calibration enables 100% functional test prior to dispatch. This calibration does not remove need for calibration & test as part of commissioning at site.
For gases other than Methane the unit has to be calibrated at site using target gas.Data represents typical values, and system conditioning may be required to achieve stated result. Contact Honeywell for details.
* Extended operating temperature range of -40°C to +65°C (-40°F to +149°F) for all sensor except for IR and H2 EC sensors, with an accuracy of +/- 30 % of applied gas from -20°C to -40°C (-4°F to -40°F) and +55°C to +65°C
(+131°F to +149°F). For the Methane IR Sensors, the accuracy is +/-10 % LEL from - 20°C to -40°C.
Long term operation at this range may cause decline in sensor performance.
** Care should be taken when setting alarm points lower than 3 ppm especially in high humidity conditions (higher than 50 % RH), since the gas reading could be lower than the actual concentration. Contact
Honeywell Analytics for any additional data or details.
