Humidity Sensors / Detectors / Transducers
Relative Humidity Sensor delivers ±1% system accuracy.
Press Release Summary:
Comprised of IC with stable polymer element and platinum RTD used for temperature compensation, sensor is resistant to airborne contaminant and chemicals. Sintered stainless steel filter protects sensor and resists effects of condensation. Offered in wall/duct/OSA mounting configurations, product is specified over -10 to +150°F and -10 to +185°F non-condensing temperature ranges. It delivers 2-point field calibration and NIST traceable calibrations.
Original Press Release:
Relative Humidity Sensor
The Relative Humidity Sensor is designed using an advanced microprocessor and guarantee system accuracies of +/- 1% in a previously unavailable economical manner.
The humidity sensor is comprised of an integrated circuit (IC) with a stable polymer element and platinum RTD that is used for temperature compensation. This sensor offers outstanding resistance to airborne contaminant and chemicals, and is protected by a sintered stainless steel filter which resists condensation.
o Wall/Duct/OSA mounting configurations
o Accuracies of 1% or 2% RH
o Temperature compensated
o Temperature output option
o Two-point field calibration
o NIST traceable calibrations
Specifications
Ambient Temperature:
Operating:
Room: -10 to 150°F (-23 to 65°C), non-condensing.
Wall/Duct/OSA: -10 to 185°F (-23 to 85°C), non-condensing.
Storage:
Room: -58 to 150°F (-50 to 65°C), non-condensing.
Wall/Duct/OSA: -58 to 185°F (-50 to 85°C), non-condensing.
Supply voltage: 9.5 to 35 VDC, non-polarized.
Voltage effect: ±.001% of span/volt from 9.5 to 35 VDC.
Loop resistance: The maximum allowable resistance of the signal-carrying loop, including extension wires and load resistors, is given by this formula: Rloopmax = (Vsupply - 9.5)/0.02 AMPS. For example, if supply voltage is 24 VDC, the loop resistance must be less than 725 ohm
Adjustments: Zero and span field adjustments, non-interacting.
Time Constant: 50 seconds in slow moving air.
Connections: Screw terminals (22-14 AWG wire).
Weight:
Room: 0.19 lb (.084 kg).
Wall/Duct/OSA: 1.20 lb (0.55 kg).
Minimum output current: 3.5 mA
Maximum output current: 23 mA.
