ProSight 120C High-Temperature Duct-Type Temperature & Humidity Transmitter

The ProSight 120C High-Temperature Duct-Type Temperature & Humidity Transmitter is an industrial environmental measurement device designed to continuously monitor air temperature and relative humidity in high-temperature ducted applications.

Unlike standard room temperature and humidity sensors, it is designed for environments where air temperatures can reach up to 120°C. It uses an advanced sensor module and high-performance single-chip electronics to measure environmental conditions and convert the measurements into standard electrical or digital output signals.

The transmitter features a stainless steel probe and an aluminum alloy head, providing a robust construction for demanding industrial and ventilation applications. Depending on the selected configuration, measurement data can be transmitted through 4-20 mA, 0-5 VDC, 0-10 VDC, or RS485 Modbus-RTU interfaces.

How Does It Work?

The ProSight 120C High-Temperature Duct-Type Temperature & Humidity Transmitter is installed in an air duct or suitable high-temperature environment, with its probe positioned to measure the surrounding air. The sensing element detects temperature and relative humidity, and the internal electronics process these signals to produce measurement outputs.

The temperature range can be configured using the internal DIN switch, while the built-in keys provide an offset adjustment function. For system integration, the transmitter can provide analog outputs such as 4-20 mA, 0-5 VDC, and 0-10 VDC, or communicate digitally through RS485 using the Modbus-RTU protocol, depending on the selected model configuration.
