User Manual

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 offers reliability over a wide range of pressures and in harsh industrial conditions and hazardous locations. It is certified 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 amplified output signal.

Chapter 2: Installation and Removal Procedures and Notes

Tools Needed

• Wrench sized appropriately for your PT-400’s process connection.
• Thread tape or sealant compound for threaded connections.

Physical Installation Notes
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

Mounting Instructions
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. 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.

Electrical Installation

• 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.

Removal Instructions
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 fitting and diaphragm of any debris (see General Care) and inspect for damage.
• Store your sensor in a dry place, at a temperature between -40°C and 82°C (-40°F to 180°F).

DANGER: Removing your PT-400 Pressure Transmitter while there is still pressure in the line could result in injury or death.

Chapter 3: Maintenance

General Care
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.

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 finished.

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. DANGER: Protective screws must be replaced using 28 oz-in of torque to create seal.
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 PT-400. (If not available, you can return it to the factory for re-calibration.)

• Ensure that the transmitter 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 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.

NOTE: You may also return the PT-400 to the factory for repair and/or adjustment.
Repair and Returns
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.
