The HE-6700 humidity elements provide independent humidity and temperature signals for use in a wide range of sensing applications, and are suitable for use with most Heating, Ventilating, and Air Conditioning (HVAC) controllers.
The humidity elements are a durable, cost-effective solution for humidity sensing. They are easy to install and factory calibrated to NIST standards. The ±2% models ship with NIST certificates of conformance to validate Johnson Controls use in demanding HVAC applications. The elements can operate in areas with little or no airflow, and recover after loss of power or saturation.
The patented All Polymer humidity element is capable of sensing over the entire range of 0 to 100% RH; its construction provides resistance to corrosion in typical HVAC environments. The temperature sensor is isolated from and operates independently of the humidity sensor.
The elements are available with three types of temperature sensors:
The temperature and humidity information from the elements can be used to calculate enthalpy, important in determining an energy-efficient and cost-effective strategy. Space and duct humidity are also important factors in overall indoor air quality. The elements allow monitoring and comparing of humidity levels with those recommended in ASHRAE Standard 62-1999.
