5 Mounting Instructions
The PT-400 should be installed in an area–indoors or outdoors–which meets the following conditions:
· Ambient temperature between -40°F and 185°F (-40°C to 85°C) · Relative humidity up to 100% · Altitude up to 2000 meters (6560 feet) · IEC-664-1 Conductive Pollution Degree 1 or 2 · IEC 61010-1 Measurement Category II · No chemical corrosive to stainless steel (such as NH3, SO2, Cl2, etc.) · Ample space for maintenance and inspection · Class II power supply Mounting your pressure transducer is easy if you follow a few simple steps:
· Ensure that the fitting on your sensor matches the fitting on your tank/vessel/pipe/etc. If the fittings do not match, do not attempt to install the sensor. Contact the factory immediately.
· 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. 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.

7 Zero Trimming
· Remove protective screw(s) with 5/64 allen wrench. · Ensure that the transducer is at 0 psig or 0 psia (vacuum if absolute). · Using a jeweler’s screwdriver or a suitable instrument, adjust the “Z” pot until you have a 4
mA, 0 V, 0.5 V, or 1 V output. · Replace protective screw(s) when finished.
NOTE: You may also return the transducer to the factory for repair and/ or adjustment.
Zero & Span Adjustment
9 General Care
Your pressure transmitter is very low maintenance and will need little car, as long as it was installed correctly. However, in general, you should:
· Keep the sensor and the area around it generally clean. · Avoid applications for which the sensor was not designed, such as extreme 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 diaphragm.
IMPORTANT: Do not make changes to the Span adjustment (the “S” pot to the right, see Figure 7.1) as part of the zero trimming. The Span should only be changed as part of the recalibration of a gauge with a known pressure source.

10 Repair 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.
· Phone: 888-525-7300 · Email: [email protected] · Online chat at www.apgsensors.com
DANGER: Protective screws must be replaced using 28 oz-in of torque to create seal.
8 Re-Calibration
This procedure requires a known pressure source of at least ±0.1% accuracy in order to fully utilize the accuracy potential of the transducer. (If not available, you can return it to the factory for recalibration.)
· Ensure that the transducer is at 0 psig or 0 psia (vacuum if absolute), and adjust zero as per instructions for zero trimming.
· Apply full scale pressure to the pressure port and adjust the Span (“S”) pot (on the right of Figure 7.1) until the full scale signal is reached.
· Re-check zero and re-adjust the zero (“Z”) pot if required · Repeat previous two steps until no further adjustment is required.
11 Removal Instructions
Removing your pressure transducer from service must be done with care. It’s easy to create an unsafe situation, or 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 -40° F and 180° F.
NOTE: You may also return the transducer to the factory for repair and/or adjustment.
