Johnson Controls HE-69135NS-0 Surface Mount Duct Sensor 0-5V 3% Relative Humidity

The Johnson Controls HE-69135NS-0 is a surface mount duct sensor specifically used to measure and record relative humidity within the HVAC systems. It has a temperature range of -4°F to 140°F and is built to be durable with a material designed from ABS plastic, thus it can effectively work in various climatic environments. The given HE-69135NS-0 produces an output voltage signal ranging from 0-5V which corresponds to the humidity level calculated by the humidistat with reference to the relative humidity interior to the ducts involved. In this way, precise control of humidity has become possible because of the compatibility of this functionality with HVAC systems.
