Johnson Controls HE-67N3-0N0BT Humidity Sensor, Wall Mount

The HE-67xx 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. User-selectable output voltage range allows choice of standard voltage outputs for use with systems in service or new systems. All-plastic material for duct probe improves thermal performance and complies with Underwriters Laboratories Inc. (UL) flammability ratings for plenum use; complies with Blue Angel (Germany) and TCO'95 (Sweden) environmental regulations.
