HMW92/93

HMW92 Humidity and Temperature Transmitters

for High Performance Building Automation Applications

Wall mounted transmitter shall incorporate a thin film polymer capacitive HUMICAP® relative humidity sensor. Accuracy shall be ± 1.7% RH for the 0 to 90% RH range and ± 2.5% RH for the 90 to 100% RH at +10 ... +40 °C (+50 ... +104 °F). Transmitter to be loop powered by 10 to 28 VDC (RL = 0*) or 20 to 28 VDC (RL = 500*), provide a linear output signal of 4 to 20 mA corresponding to 0 to 100% RH. Incorporates a digital temperature sensor that provides a linear output signal of 4 to 20 mA corresponding to -5° to 55°C (23° to 131°F). Accuracy to be ±0.2°C (0.36°F) at +20…+30 °C (+68 ... +86 °F). Shall have the option to calculate and output additional parameters: dew point, mixing ratio, enthalpy, absolute humidity, and wet bulb temperature. Transmitter shall have the ability to calibrate relative humidity, without disturbing operation, using a single point electronic field calibrator or have an interchangeable humidity and temperature module with a NIST traceable calibration for easy maintenance. NIST traceable calibration and certificate included.

Wall mounted transmitter shall incorporate a thin film polymer capacitive HUMICAP® relative humidity sensor. Accuracy shall be ± 1.7% RH for the 0 to 90% RH range and ± 2.5% RH for the 90 to 100% RH at +10 ... +40 °C (+50 ... +104 °F). Transmitter to be powered by 18 ... 35 VDC or 24 VAC and provide a linear output signal of 0…5V or 0…10V corresponding to 0 to 100% RH. Incorporates a digital temperature sensor that provides a linear output signal of 0 to 5V or 0 to 10V corresponding to -5° to 55°C (23° to 131°F).
