High-Temperature Duct Temperature & Humidity Transmitter | ProSense
Industrial-grade duct-mounted temperature and humidity transmitter with stainless steel probe, wide range up to 120°C, and multiple output options.
The ProSense High-Temperature Duct Temperature & Humidity Transmitter is engineered for accurate measurement in demanding high-temperature and high-humidity environments. Featuring a Swiss-made advanced sensor module and high-performance single-chip design, it delivers excellent stability, precision, and long-term reliability.
With a measurement range of –20°C to 120°C and 0–100%RH, this duct-mounted transmitter is ideal for HVAC systems, industrial drying processes, ovens, greenhouses, food storage, and building automation. The rugged design includes a stainless-steel probe and aluminum alloy head for superior durability under extreme conditions.
Multiple output options — 4–20mA, 0–5VDC, 0–10VDC, and RS485 (Modbus-RTU protocol) — allow seamless integration with automation systems, PLCs, and monitoring platforms. Additional features include DIN switch range adjustment, offset calibration, and customizable stem length and thread sizes.
Protected by IP65 electrical housing and IP54 sensor sealing, this transmitter ensures reliable performance even in harsh environments.
ProSense delivers high-quality duct temperature and humidity transmitters designed for industries that require precision, durability, and versatility in extreme applications.
