Duct-Mounted Temperature and Humidity Transmitter Power 24VDC, RS-486 Comm. Mddbus RTU 1ch Analog Output: Individual Current Output for Temperature and Humidity 1ch each 3ea Input Switches, 4digit x 2ea Segment Display, One Touch Wiring and Basic Water Resistance (Wall-Mounted) The THX-Dx-PM temperature and humidity transmitter is a new-generation product that inherits the reliability of long-selling sensor-based transmitters while maintaining a cost-effective price point. It features analog current output for both temperature and humidity, preserving the advantages of range-specific output settings. The one-touch open design, combined with an upgraded splash-resistant enclosure, enhances installation convenience and maintenance efficiency. The one-touch wiring terminal block reduces installation time stress in large-scale setups, improving usability and offering a versatile installation solution. The transmitter utilizes a Sensirion low-power CMOSens chip. The built-in capacitive humidity sensor operates on the principle of a dielectric polymer that absorbs or releases water in proportion to ambient relative humidity. This results in a change in the dielectric constant, which is measured through the sensor’s integrated circuit. The temperature measurement is implemented using a Bipolar Junction Transistor (BJT) for enhanced accuracy. A low-pass filter program is applied to the measured data to ensure stable and noise-free conversion values.
