Temperature/Humidity Transducers THD Series

Product Overview

The THD series temperature/humidity transducers are designed with advanced temperature and humidity sensors to deliver precise environmental monitoring. These transducers offer versatile output options, including DC 4-20 mA, 1-5 VDC, and RS485 communication, making them adaptable to various applications. The temperature sensors cover a range from -19.9 to 60.0°C, while the humidity sensors measure from 0.0 to 99.9% RH. Available in different configurations—room type, duct mount type, and wall mount types—the THD series is engineered to meet diverse installation needs.
