Mounting Instructions
•
Attach the wires of your PT-500 to your control system according to the pinout table above.
• Electrical Installation
• Electrical Pinout Table and Supply Power Table
Your PT-500 can be mounted in three ways: via NPT process connection, free-hanging suspension, or con
-
duit mounted. Mounting your pressure transducer is easy if you follow a few simple steps:
•
Never over-tighten the sensor. This can compress the diaphragm, changing how it reacts to pressure.
In all cases, tighten the sensor as little as possible to create an adequate seal. On straight threads,
tighten only until you feel the o-ring compress - making sure you don’t damage or extrude the o-ring.
•
Always use thread tape or sealant compound on tapered threads. Wrap thread tape in the opposite
direction of the threads so it does not unravel as you screw the sensor into place. Unraveling can cause
uneven distribution and seal failure. For straight threads use an o-ring.
•
Always start screwing in your sensor by hand to avoid cross-threading. Thread failure can be a problem
if you damage threads by over-tightening them or by crossing threads.
•
For suspension mounting the PT-500, drill a 3/16” hole into the 1/2” NPTF to 1/2” NPTF hex coupler
(P/N 511414) and secure it to the 1/2” NPTM coupler fitting of the PT-500. Attach a .060” diameter 316L
SS cable of desired length to the hex coupler and secure the steel cable according to your application
requirements.
•
Wrench sized appropriately for your PT-500’s process or conduit connection.
•
Thread tape or sealant compound for threaded connections.
