Introduction
Thank you for purchasing a PT-500 Analog Output series submersible pressure transmitter from APG.
We appreciate your business! Please take a few minutes to familiarize yourself with your PT-500 and this
manual.
PT-500 submersible pressure transmitters oer reliability in harsh industrial conditions and hazardous
locations. The 4-20 mA model is certied intrinsically safe for hazardous areas in the US and Canada
by CSA for Class I, Division 2, Groups C and D, Class I, Zone 2, Group IIB, and Class I, Division 1, Groups
C and D, Class I, Zone 0, Group IIB environments. The small size, integrated electronics, wide operating
temperature range, and durability make the PT-500 the perfect instrument for static and dynamic pressure
measurement.
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 Certicate of Compliance at the back of this manual for further details.
IMPORTANT: Your 4-20 mA PT-500 MUST be installed according to drawing 9002803
(Intrinsically Safe Wiring Diagram or Non-Incendive Wiring Diagram) 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
• 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 tting 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.
• Tools Needed

Removing your PT-500 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:
• For sensors installed via NPT process connection, make sure the pressure is completely removed from
the line or vessel. 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).
• For suspended sensors, retrieve the sensor from the vessel. Follow any and all procedures for safely
isolating any media contained inside the line or vessel.
• Carefully 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 process connected PT-500 Pressure Transmitter while there
is still pressure in the line could result in injury or death.
Your PT-500 series pressure transmitter is very low maintenance and will need little care as long as it is
installed correctly. However, in general, you should:
• For process connected sensors, 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 only with extreme care. If using a tool is required, make
sure it does not touch the diaphragm.
Chapter 3: Maintenance
• General Care
IMPORTANT: Any contact with the diaphragm can permanently damage the sensor.
Use extreme caution.
NOTE: If your PT-500 has a vent tube, do not seal, cover, or close the vent tube with
anything other than an APG-provided venting cap or desiccant drying cartridge (See Fig-
ure 4.1 and 4.2). Unapproved seals or covers will prevent proper sensor operation.

• Zero Adjust (4-20 mA, 0-5 VDC, and 0-10 VDC only)
The zero output (4mA, or 0 VDC) can be adjusted by holding a magnet perpendicular to the can,
approximately 1-1/2” from the top or bottom of the can.
Holding the magnet close to the top of the can increases the output (See Figure 3.1). Holding the magnet
close to the bottom of the can decreases the output (See Figure 3.2).
If the zero output values do not change right away, hold the magnet in place near the top of the can until
the values change, for up to two minutes. If there is no change, repeat the procedure near the bottom of the
can. If there is still no change, consult the factory.
Unvented PT-500A transmitters do not automatically adjust to changes in barometric pressure. We recom-
mend that PT-500A transmitters be zeroed upon receipt, and after major weather events.
Condensation in the vent tube can damage the electronics in your sensor, resulting in unreliable readings.
APG oers two methods of preventing vent tube condensation: a venting cap, and a desiccant drying
cartridge.
The venting cap is a PVC tube with a hydrophobic patch that allows moisture to pass out of the tube without
allowing water in (See Figure 3.3). The cap is sealed by an o-ring, and is easily installed in the eld.
The desiccant drying cartridge with vent tube adapter absorbs any moisture in the vent tube to keep vapor
from condensing (See Figure 3.4). The installation of the desiccant drying cartridge is quick and easy.
Common installation methods are cable tie, Velcro, and cable clamps.
• Vent Tube Drying
NOTE: Span calibration must be done at the factory for all analog models.
