HE-67N3-0N0GS TRUERH-Surface-mount Duct Humidity/Temperature Sensors

The TrueRH-product line delivers ±2% and ±3% Relative Humidity (RH) Sensing Products in a full variety of packages. The humidity sensor¿s All-Polymer-construction increases resistance to corrosion in HVAC (Heating, Ventilating, and Air Conditioning) environments. HE-67xx Elements are products whose output signal is 0 to 5 VDC for humidity Indication. The HE-67xx Series sensors combine humidity and temperature sensing in an all-plastic enclosure used inside ducts and economizer rooftop systems. These models are available with a nickel or one of two thermistor temperature sensors. The thermistor temperature sensors have a negative temperature coefficient, and a reference resistance of 2.2k ohms or 10.0k ohms. The nickel temperature sensor has a reference resistance of 1.0k ohms. These units can be powered with 14 to 30 VDC or 20 to 30 VAC and feature a 0 to 5 VDC output.Features: TrueRH-Circuitry and calibration techniques for which patient protection is pendingAll-Polymer humidity sensor's patented sensing element improves sensor's resistance to corrosionhumidity and temperature sensor in one unit eliminates need for separate sensors; reduces installation time and cost2% RH accurate model includes a National Institute of Standards and Technology (NIST) certificate of conformance that documents higher precision for 2% modelssenses RH over full 0 to 100% range to accommodate a wide range of applicationsprotective membrane protects sensors from contaminationquick-mount, 2 screw installation reduces installation timecompact enclosure for mounting inside ducts-designed for rooftop unit applications and retrofits; enables surface mount installation Product Specifications BRANDJohnson Controls LENGTH INCHES3 WIDTH INCHES3 HEIGHT INCHES1-3-16 RH ACCURACY±3 Percent POWER REQUIREMENTS14 to 30 VDC or 20 to 30 VAC at 50/60 Hz, Class 2 SENSOR TYPE1.0k ohm Nickel Sensor LIMITED WARRANTY YEARS1
