IMPORTANT
Cable shielding should ONLY be connected to the
GROUND terminal at the PWTA transmitter. DO
NOT connect cable shielding at the pressure sen-
sor.
Picture above shows the 5 wires connected prop-
erly from the sensor to the PWTA transmitter (+/-
voltage supply (terminals 1 and GROUND), +/-
feedback from transducer (terminals 2 and 3) and
shield wire (GROUND terminal).
8. Connect conduit fittings to the sensors and PWTA
transmitter. Use water tight fittings if required by
your installation conditions.
9. Wire PWTA transmitter for voltage or current output
as shown (Remote zero wiring is optional):
10. Use the following diagram for the remaining config-
uration of your PWTA system.

12. Verify the PSIG jumper matches the PSIG rating on
the sensors.
Sensor Identification:
PWTA40-X = 100 PSIG
PWTA100-X = 100 PSIG
PWTA250-X = 250 PSIG

13. Select differential pressure range using RANGE
switch. Identify if your PWTA transmitter is labeled a
PWTA40, PWTA100, or PWTA250 model. Each
Transmitter provides three PSID ranges based on the
PSIG rating on sensors A and B. Use the appropriate
