Description
1
PT-500 submersible pressure transmitters offer reliability in harsh industrial conditions and
hazardous locations. The 4-20 mA version is certified 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.
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-500 will look something like this:
 SAMPLE: PT-500-400-FTH2O-G-L1-E0-P37-N0-500
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 also includes the pinout, as does this installation guide.
You'll also find all hazardous certification information on the label.

Mounting Instructions
4
The PT-500 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 NH
• Ample space for maintenance and inspection
• Class II power supply
Your PT-500 can be mounted in three ways: via NPT process connection, free-hanging suspension,
or conduit 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.
• 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.
• 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 fitting 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.
