Introduction
::
Pantech's
Two Wire Transmitters, model 872
is designed over low drift, low power components. It is designed
to provide 4-20mA dc signal on the same two wires, which carry the
24 V DC for variety of inputs. The transmitter is an ideal choice
for temperature measurement with RTD’s. It provides a current
output signal of 4 – 20mA DC capable of driving a load of
upto 650 . This
eliminates needs to run compensating cable or three core cable between
the field and control room.
The
instrument can be calibrated throughout the range of RTD. The output
is linear with respect to temperature for RTD input.
The
transmitter is available in field mounted housings with or without
local display. The local 3-½ digit loop powered display reduces
the load capability of the transmitter to around 500 .
Also the transmitter is available in weather or explosion proof
housing.
