The Carrier 33ZCSENSRH-02 is a space-mounted relative humidity sensor designed for reliable indoor RH measurement in commercial HVAC applications. Using advanced ceramic sensing technology, it maintains accuracy even after exposure to condensation and supports both 4–20 mA and 0–10 Vdc outputs for flexible system integration.
The sensor converts resistance into a linear 4–20 mA or 0–10 Vdc signal, giving engineers options when connecting to different control platforms. Current output supports long wire runs using standard twisted-pair cabling without signal degradation. This simplifies installation while maintaining measurement integrity.
Built for interior wall mounting, the 33ZCSENSRH-02 is optimized for space humidity monitoring in commercial environments. Its non-communicating design makes it a straightforward choice for traditional control architectures. The sensor supports stable HVAC operation without adding system complexity.
33ZCSENSRH-02 Space Relative Humidity Sensor provides accurate indoor RH measurement with ceramic sensing technology and flexible control outputs.
