Johnson Controls Duct Probe Humidity Transmitter w/ Thin-Film Nickel Temp. Sensor

The HE-69xx Series Humidity devices house both a humidity and a temperature sensor in a wall or duct-mount style. The humidity sensor is capable of measuring Relative Humidity (RH) over the entire range of 0 to 100%, and its All-Polymer construction provides improved resistance to chemical corrosion. The TRUERH product line delivers devices with RH accuracy of either ±2% or ±3% RH. TRUERH humidity elements produce voltage output signals proportional to measured humidity for humidity indication. Temperature sensors are available in thin-film nickel, thin-film platinum, and silicon. The elements are powered with 14 to 30 VDC or 20 to 30 VAC and feature a user-selectable humidity output of 0 to 10 VDC or 0 to 5 VDC. Features: TRUERH circuitry and calibration techniques for which patent protection is pending All-Polymer humidity sensor patented sensing element provides accurate and reliable humidity sensing tested and calibrated with equipment certified to be in compliance with National Institute of Standards ...
