In process plant many signals are generated at field. These signals are generated at field sensors like position transmitter, temperature sensor, voltage, power transmitter.
These signals are not isolated from input and not suitable for transmission over long distance. Converters are specially developed to overcome these problems in transmission such as line drop, interference, ground looping, and non compatibility to standard processing unit.
Temperature Transmitters receives signal from field temperature sensor like (Pt 100, thermocouple) & convert these in suitable form like 4-20mA. These are generally head mounted type and housed in the compact terminal compartment of temp sensor..
Signal Isolator: I/P 4-20 mA, O/P: 4-20 mA
Signal Converter: I/P from field transducer. O/P: as per requirement
Signal Repeater: I/P : One O/P : Multiples
Head Mounted Temp Transmitters: I/P: RTD or thermocouple: O/P 4-20 mA
1) Complete galvanic isolation between input output and control supply.
2) Independent zero and span adjustments
3) Stable current output eliminates need for special cable, shielding.
4) Robust cast Al.enclosure suitable for field mounting.
