Humidity and temperature transmitter LIBRATHERM INSTRUMENTS

Product Description:

Libratherm offers Relative Humidity and Temperature transmitter model HTX-3000 for measuring and transmitting the analogue and digital values proportional to these two parameters. HTX-3000 is designed using the latest micro-controller, incorporating Pt-100 class A element for temperature sensing and Monolithic sensor for %RH sensing. The two independent loop current outputs of 4-20mA proportional to both the parameters are available for remote measurement and indication. To suit industrial requirement the transmitter is available in both duct type and wall mounting type

assembly, and for the local indication of %RH and Temperature, two independent 4 digit 7 segment red LED displays are provided. For serial 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. Using RS 485 interface is advantageous, since number of wires as with the three wire of 4-20mA per transmitter can be avoided (3 wires multiply by no. of transmitters), since only two wires can be looped with multiple transmitters in multi-drop wiring. These transmitters finds application in HVAC, Climatic control, Stability chamber, Hospitals, Green houses, useful for Validation agencies and for regulatory requirement of FDA, CGMP, ISO14644 etc….
