资料
Hydrocarbon Sensor
Operation – continuous diffusion NDIR (duel wave-length)
Measuring Range – Standard 0~100% LEL 0~100% Vol
Others available
Accuracy ± 5% F.S.D
Warm up time to zero < 20 seconds
Response time to target gas T90 < 35 seconds
Long term zero drift ± 5% F.S.D
The 4~20mA output provides a fault indication by reducing the output to below 2mA,
with the recovery from fault condition being automatic.
