Use a multimeter to test the flame sensor's microamp signal. A reading below the manufacturer's specified range (often 2-6 microamps) suggests a failing sensor. Repeated Cleaning Required: If the sensor requires frequent cleaning to function, it may be nearing the end of its life and losing reliability.. 1 | sps.honeywell.com FLAME PRODUCT GUIDE TABLE OF CONTENTS Table of Contents: FS SERIES DETECTORS* 02 FS Reference Chart 03 FS Industrial Applications Chart 04 FS24X Plus Triple Infrared Flame Detector 06 FS20X Multi-Spectrum Flame Detector 08 FS10 Multi-Spectrum Flame Detector 11 FS7 Multi-Spectrum Flame Detector FSL100 DETECTORS* 13 FSL100 Reference Chart 13 FSL100 Commercial Applications Chart
The job of a flame sensor is to send a signal to the gas valve to stay open. You can test a flame sensor using a multimeter set to measure microamps in series between the sensor terminal and the wire that leads to the gas valve.. Turn up the thermostat to call for heat and check the meter reading when the burners ignite. It should read.. A flame sensor reading chart provides critical insights into temperature detection mechanisms, revealing how sensors interpret thermal signatures across various industrial environments. By mapping precise temperature ranges, gain settings, and calibration parameters, these charts enable engineers and technicians to understand complex thermal.
