HHX-440-DM – Duct Mount Humidity Sensor cum Transmitter.
Size (mm): 76 x 70 x 38 (H x W x D)
Libratherm offers a low cost, rugged and reliable Duct Mount Humidity Transmitter HHX-440-DM for sensing T or RH or T + Rh in the environment and transmitting the proportional analog values (4-20) mA or (0-10) VDC.
Normally, the signal generated by T+RH sensors is low in strength hence cannot be transmitted over a very long distance, and if done so the signal is likely to drop over a very long cable which will result in the inaccurate measurement of temperature and %RH.
The High Precision Humidity and Temperature Transmitter featured here converts these low-level signals from Pt-100 and Rh sensor to equivalent 4-20mA/0-10Vdc linear analog signal, which can be transmitted over a very long distance without loss of accuracy in the measurement. Dual 4-20mA proportional to T and %RH can be used for remote measurement and indication and control.
This Industrial Grade Temperature Transmitter operates on a 24VDC power supply and is housed in an ABS plastic enclosure with perforation for sensing. The 24VDC supply and 4-20mA are electrically isolated from each other and hence prevent any ground line interferences or loading effect, while connecting to any external measuring/controlling devices like DCS, PLC, BMS controller, HMI, DDC, or PID controllers. Standard 4 core or 6 core 2-meter cable with end terminal is attached to the transmitter for ease of connection and wiring.
