Two Wire Signal Transmitter

We are exporting, manufacturing & supply a wide range of Two Wire Signal Transmitter from Pune, Maharashtra, India. PROTOCONTROL offers Signal Converters, Isolators and transmitters to isolate and convert field signals like resistance, current, voltage, frequency to 4-20 mA. These Two Wire Signal Transmitter find use in process control industries for signal isolation. Variety of models is available for specific applications.

Protocontrol provides 2-wired signal transmitters. Transmitters are generally head mounted and fitted in the head of temperature sensor; Isolators provide further isolation of field signal so that PLC side is isolated from field side.

In the field, many signals are generated such as motor current, armature voltage, position feedback in the form of change in resistance or signals obtained from various types of traducers in standard voltage or current form. 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.

Salient features:
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
