TN206 Extending Life Of LEL Sensors In Field ... Honeywell

Note: Sensor exposure to a high concentration of methane or other hydrocarbon gases often may significantly decrease the sensor life. Note: In very few cases, if the LEL sensor reading shows errors and cannot pass fresh air calibration, then the sensor may need replacement. LEL sensor cleaning has a longterm effect (refer to the table below). Zero and span calibration within 5 and 11 weeks ...

HANDLING LEL SENSOR POISONS

HANDLING LEL SENSOR POISONS It is well known that certain chemicals inhibit or poison the catalytic bead in LEL (combustible) sensors, leading to partial or complete . loss of sensitivity. Poisoning is defined as a permanent degradation, while inhibition is usually recoverable by exposure to clean air. For the best sensor performance, it is crucial for both instrument users and manufacturers ...
