33ZCSENDRH-02
The sensor's advanced ceramic technology design overcomes the limitations of other resistance-based humidity sensors that utilize water soluble polymer coatings. The advanced ceramic technology enables the sensor to fully recover from condensation, allowing it to maintain accuracy over longer periods of time than other humidity sensors utilizing water soluble polymer coatings.
The Carrier 33ZCSENDRH-02 is a duct-mounted relative humidity sensor designed for dependable humidity measurement in commercial HVAC systems. Its ceramic sensing element maintains accuracy even in demanding airside applications, supporting consistent system performance and control.
The sensor converts resistance to either a 4–20 mA or 0–10 VDC linear output, supporting compatibility with a wide range of control systems. This flexibility simplifies integration into new or existing HVAC installations. Long-distance signal transmission is supported without sensitivity to electrical noise.
Designed to outperform traditional polymer-based humidity sensors, the ceramic element resists degradation caused by moisture exposure. This helps reduce drift and maintenance needs over the life of the system. Facility teams benefit from dependable readings and reduced service interruptions.
33ZCSENDRH-02 Duct Relative Humidity Sensor provides stable, accurate duct humidity measurement using ceramic sensing technology for long-term performance.
