Description
The T752 accepts potentiometer
inputs from 0 to 50 Ohms to
0 to 200k Ohms (end to end).
The T752 provides 600 VDC of
isolation with outputs of either
4-20mA or 10-50mA which are
field selectable via top accessed
DIP switch. The current outputs
are in proportion to the potentiometer
input. Urethane coating of internal
circuitry for protection from
corrosive atmospheres is included
as standard.
The
T752 has 80% zero and span adjustability
within the input range of the
potentiometer. This allows the
user to field calibrate the
unit for a wide variety of input
spans from the maximum (100%)
down to any minimum (20%) span
(e.g., 4% to 24%) as long as
the adjusted span remains within
the input range of the potentiometer.

Application
The T752 is useful in any application
requiring isolation of a 2-wire
loop current from a 3-wire potentiometer.
Typical applications include
tank level data acquisition
and position sensor conditioning.
The output of the T752 can be
used to drive a digital meter
for direct display or interface
with a computer for monitoring
or control.
The
T752 is FM approved for intrinsically
safe operation in Class I, Division
1, Groups A, B, C, and D; Nonincendive
Class I Division 2, Groups A,
B, C and D, and Classes II &
III, Division 2, Group G hazardous
locations when installed per
manufacturer's drawing 790-0024-00.
