Overview

The 33ZCSENORH-02 is an outdoor relative humidity sensor designed for dependable HVAC control. Its ceramic sensing element maintains accuracy in challenging outdoor conditions and integrates easily with Carrier control systems.

Features

Advanced ceramic sensing technology resists performance drift caused by moisture exposure. Unlike polymer-based sensors, it recovers fully from condensation to help maintain consistent humidity readings over time. This supports more stable HVAC operation in changing weather conditions.

The sensor converts humidity measurements into either a 4–20 mA or 0–10 VDC signal. This flexibility allows straightforward integration with a wide range of building control systems. Long-distance signal transmission helps preserve accuracy without added complexity.

Designed as a non-communicating sensor, the 33ZCSENORH-02 offers uncomplicated setup and reliable operation. Its durable construction supports outdoor mounting while minimizing maintenance needs. The result is dependable performance without additional network requirements.

33ZCSENORH-02 Outdoor Relative Humidity Sensor provides stable outdoor humidity measurement using ceramic sensing technology for consistent HVAC control.
