NAP-57A

NAP-57A

Supply voltage: AC 2.5 ± 0.25V (50-60Hz), DC 2.5 ± 0.25V

Current (when 2.5V is added): AC 160 ~ 180mA (50-60Hz), DC 160 ~ 180mA

Range of ambient temperature and humidity during operation: ambient temperature: -20 to + 60 ° C, relative humidity: 95% RH or less (non-condensing)

Temperature and humidity range during storage: ambient temperature: -30 to + 70 ° C, relative humidity: 95% RH or less (non-condensing)


The sensor can detect all flammable gases except acetylene, with a detection range of 1% to 100% LEL, and within 50% LEL can reach a detection accuracy of ± 10%.
