APG PT-300 User manual

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:
The model number correlates with all the congurable options and tells you exactly what you have.
Compare the model number to the options on the datasheet to identify your exact conguration.
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 nd all hazardous certication information on the label.

5Mounting Instructions
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.

8General Care
Your pressure transmitter is very low maintenance and will need little care. As long as it was
installed correctly, it can be However, in general, you should:
• Keep the sensor and area around it generally clean.
• Avoid applications for which the sensor was not designed, such as extrememe temperatures,
contact with incompatible corrosive chemicals, or other damaging environments.
• Inspect the threads whenever you remove the sensor from duty or change its location.
• Avoid touching the diaphragm. Contact with the diaphragm, especially with a tool, could
permanently shift the output and ruin accuracy.
• Cleaning the diaphragm or the diaphragm bore should be done with extreme care. If using a
tool is required, make sure it does not touch the diaphram.
9Repair Information
If your pressure transmitter needs repair, contact us via email, phone, or online chat on our
website. We will issue you an RMA number with instructions.

7Removal Instructions
Removing your pressure transducer from service must be done with care. It’s easy to create an
unsafe situation, or to damage your sensor, if you are not careful to follow these guidelines:
• Make sure the pressure is completely removed from the line or vessel where your sensor is
installed. Follow any and all procedures for safely isolating any media contained inside the line
or vessel.
• Remove the sensor with an appropriately sized wrench (per your process connection).
• Clean the sensor’s threads of any sealant compound or tape. Inspect the threads and the
diaphragm for any damage.
• Store your sensor in a dry place between 14° and 140° F (-10° - 60° C).
DANGER: Removing the pressure transmitter while there is still pressure in the line or
vessel could result in injury or death.
IMPORTANT: Any contact with the diaphragm can permanently damage the sensor. Use
extreme caution.
