Temperature process transmitter LIBRATHERM INSTRUMENTS

Product Description:

Libratherm offers micro-controller based Process Transmitter model PTX-3000 for measuring and transmitting the analogue and digital values proportional to the Process Input. It can accept the universal input, which is user selectable using internal DIP switch. Three options are available, where user can specify the model for universal input, any of the two fixed input or any of the single fixed input. The current output of 4-20mA proportional and linearized to the process input is available for remote measurement and indication. For dual input model, two independent 4-20mA are available. To suit industrial requirement the transmitters are available with and without display.

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 the RS 485 interface is advantageous, since number of wires coming from the various sensors can be avoided and instead only two wires can be used to interface on serial port. For example, for a large heating system incorporating 16 thermocouples, under conventional method 16 dual core cables will run from the system to the control panel, where as in case of RS485 interface, only two wires will run from the system to the control panel.
