Introduction
Thank you for purchasing a PT-400 series pressure transmitter from APG. We appreciate your business!
Please take a few minutes to familiarize yourself with your PT-400 and this manual.
The PT-400 series of pressure transmitters oers reliability over a wide range of pressures and in harsh
industrial conditions and hazardous locations. It is certied intrinsically safe for hazardous areas in the US,
Canada, Europe and internationally by CSA, ATEX, and IECEx for Class 1, Zone 0 environments. The small
size, integrated electronics, wide operating temperature range, and durability, make the PT-400 the perfect
instrument for static and dynamic pressure measurements with an amplied output signal.
Reading your label
Every APG instrument comes with a label that includes the instrument’s model number, part number, serial
number, and a wiring pinout table. Please ensure that the part number and pinout table on your label
match your order. The following electrical ratings and approvals are also listed on the label. Please refer to
the Certicate of Compliance and at the back of this manual for further details.
IMPORTANT: Your PT-400 MUST be installed according to drawing 9002794 (Intrinsi-
cally Safe Wiring Diagram or Non-Incendive Wiring Diagrams) as indicated above to meet
listed approvals. Faulty installation will invalidate all safety approvals and ratings.

Chapter 2: Installation and Removal Procedures and Notes
• Mounting Instructions
Mounting your pressure transducer is easy if you follow a few simple steps:
• Ensure that the tting on your sensor matches the tting on your tank/vessel/pipe/etc. If the ttings 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. 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.
• Wrench sized appropriately for your PT-400’s process connection.
• Thread tape or sealant compound for threaded connections.
• Tools Needed
The PT-400 should be installed in an area--indoors or outdoors--which meets the following conditions:
• Ambient temperature between -40°C and 85°C (-40°F to +185°F)
• 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 chemicals corrosive to stainless steel (such as NH3, SO2, Cl2 etc.)
• Ample space for maintenance and inspection
• Class II power supply
• Physical Installation Notes

6Tel: [phone] • Fax: [phone] • www.apgsensors.com • [email protected]
• Check the pinout table on your PT-400 against your order.
• Check that your electrical system wiring matches the pinout table on your PT-400.
• For instruments with connectors, make the connection. Otherwise, attach your wires to the provided
terminal strip.
• Electrical Installation
Removing your PT-400 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 tting and diaphragm of any debris (see General Care) and inspect for damage.
• Store your sensor in a dry place, at a temperature between -40° F and 180° F.
• Removal Instructions
DANGER: Removing your PT-400 Pressure Transmitter while there is still pressure in
the line could result in injury or death.

Tel: [phone] • Fax: [phone] • www.apgsensors.com • [email protected]
Your PT-400 series pressure transmitter is very low maintenance and will need little care as long as it is
installed correctly. However, in general, you should:
• Keep the transmitter and the area around it generally clean.
• Avoid applications for which the transmitter was not designed, such as extreme temperatures, contact
with incompatible corrosive chemicals, or other damaging environments.
• Inspect the threads whenever you remove the transmitter 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.
• Clean the diaphragm or the diaphragm bore with extreme care. If using a tool is required, make sure it
does not touch the diaphragm.
Chapter 3: Maintenance
• General Care
• Zero Trimming
• Remove protective screw(s) with 5/64 allen wrench.
• Ensure that the transmitter 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 screws(s) when nished.
IMPORTANT: Do not make changes to the Span adjustment (the “S” pot to the right,
see Figure 3.1) 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.
Figure 3.1
Zero & Span
Adjustment
DANGER: Protective screws must be replaced using 28 oz-in of torque to create seal.

Should your PT-400 series pressure transmitter require service, please contact the factory via phone, email,
or online chat. We will issue you a Return Material Authorization (RMA) number with instructions.

• Online chat at www.apgsensors.com
Please have your PT-400’s part number and serial number available. See Terms & Conditions (https://www.
apgsensors.com/about-us/terms-conditions) for more information.
• Repair and Returns
This procedure requires a known pressure source of at least ±0.1% accuracy in order to fully utilize the
accuracy potential of the PT-400. (If not available, you can return it to the factory for re-calibration.)
• Ensure that the transducer is at 0 psig or 0 psia (vacuum if absolute), and adjust zero as per instruc-
tions for zero trimming.
• Apply full scale pressure to the pressure port and adjust the Span (“S”) pot (on the right of Figure 3.1)
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.
• Re-Calibration
NOTE: You may also return the PT-400 to the factory for repair and/or adjustment.
