> Introduction ::

Pantech's Pressure Two Wire Transmitter, Model 875 is ideal instrument to provide 4 – 20 mA DC signal on the same two wires which carry the 24V DC power for pressure measurement. The transmitter is an ideal choice for converting any pressure range (maximum upto 300 bars) to a current signal of 4 – 20 mA DC. It provides a current output signal capable of driving load upto 600.

The converter is available in field mounted housings with or without local digital display. The local 3-½ digit loop powered LCD display. In case of digital display P to I converter the current output load capacity reduces to 400. The transmitter is available in weatherproof or explosion proof housing. It is also available in housing suitable for wall mounting in control room.

The modules incorporate state of the art pressure input integrated circuit (USA make), low drift operational amplifiers and industrial grade components. Burn in of each module ensures a long trouble free operation.
