Libratherm offers T RH sensor with Transmitter model HYGROTX-3000 for measuring and transmitting the analogue values proportional to both T and RH Input. The signal
generated by Hygroclip is of the order of 1 volt DC and cannot be transmitted over very long distance and if done so the signal is likely to drop over very long cable which will result in the inaccurate measurement of temperature and %RH. The transmitter featured here converts the
low level signal to equivalent 4-20mA, which can be transmitted over a long distance without loss of accuracy in the measurement. Dual output of 4-20mA proportional to T and %RH can be used for remote measurement and indication. To suit industrial requirement more advanced transmitters model HTX-3000 are also available with local display. To facilitate interface with PLC or DCS or with any other process controller – digital serial communication on RS485 bus with MODBUS RTU protocol in slave
mode is also provided.
