Family Overview Michell SF Series sensors accurately measure temperature and relative humidity, dew point, and provides 4-20 mA or voltage signal output. Rugged housing can withstand 20 barg pressure, so that the sensor can be used in the SF series measuring dew point and relative humidity on many occasions. Highlights for OEM applications designed dew point temperature or relative humidity output buffer type filters are designed to minimize traffic impact on its excellent measurement accuracy and temperature compensation performance indicators dew point temperature range -40 ~ + 60 ° C, dew point temperature absolute humidity range 0 to 200g / m3 Accuracy (dew point) <± 2 ° C (-40 ~ + 60 ° C) Accuracy (absolute humidity) 0.4 to 3g / m3 depending on the numerical stability of the absolute humidity of <1 ° C / Year Response time T90 <10 second Input / Output Output signal 0-1, 0-5, 0-10 V or 4-20 mA Supply voltage 8-30 V DC (14-30 V DC 0-10 V output corresponds) Supply Voltage Effect of ± 0.005% RH / V Current consumption 9 mA + load current supply voltage change ± 0.005% RH / V Operating conditions Operating temperature 0-95% RH (non-condensing) Probe, Housing, Storage Operating humidity Probe, housing -30 to + 85 ° C Storage -40 ~ + 85 ° C maximum working pressure 20 barg temperature coefficient within the operating range of the mechanical properties of the sealing temperature compensation Protection class IP65 (NEMA 4 level) Housing material nickel plated brass Dimensions L = 85mm,? 24mm (max ) filter front-end filter weight 320g HDPE mechanical connection G1 / 2 "BSP (DIN ISO 228) or 1/2" NPT cable 2m
