The PT-300 series pressure transmitter offers reliability over a wide range of pressures and in harsh
industrial conditions.
How To Read Your Label
2
Each label comes with a full model number, a part number, and a serial number. The model
number for the PT-300 or PT-301 will look something like this:
 SAMPLE:
PT-300-L1-100-psi-G-E5-5-P5-N3-M1-S0
The model number correlates with all the configurable options and tells you exactly what you have.
Compare the model number to the options on the datasheet to identify your exact configuration.
You can also call us with the model, part, or the serial number and we can help you.
The label aslo includes the pinout, as does this installation guide.
You'll also find all hazardous certification information on the label.

Mounting Instructions
5
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, tigthen 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. Straight threads use an
o-ring. If using thread tape, wrap the tape in the opposite direction of the threads so it does
not unravel as you screw it into place. Unraveling can cause uneven distribution and seal
failure.
• 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.
