Chapter 2: Installation and Removal Procedures and Notes

• Tools Needed

• Wrench sized appropriately for your PT-405’s process connection.

• Thread tape or sealant compound for threaded connections.

• Physical Installation Notes

The PT-405 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

• Explosion proof conduit, with seal installed within 18 inches, must be used for cable connection to PT-

405.

• Class II power supply

 IMPORTANT: Incorrectly connecting your PT-405 Pressure Transmitter to explosion

proof conduit, or using unapproved conduit, will void the protection rating of your PT-405.

• Mounting Instructions

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.

• Electrical Installation

• Check the pinout table on your PT-405 against your order.

• Check that your electrical system wiring matches the pinout table on your PT-405.

• Connect cable from PT-405 to your control system.

 DANGER: Incorrectly connecting your PT-405 Pressure Transmitter to your control

system could result in injury or death.

• Removal Instructions

Removing your PT-405 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.

DANGER: Removing your PT-405 Pressure Transmitter while there is still pressure in



the line could result in injury or death.

Chapter 3: Maintenance

• General Care

Your PT-405 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 unit from Hazardous Location prior to performing Zero Trimming procedure.

• Remove the protective screw.

• Ensure that the transmitter is at 0 psig or 0 psia (vacuum if absolute). For compound ranges, i.e., -15

psi to 30 psi, the 4 mA, 0 V, 0.5 V, or 1 V set point is also at vacuum.

• 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.

 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.

Adjustment

• 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-405. (If not available, you can return it to the factory for re-calibration.)

• Remove unit from Hazardous Location prior to recalibration.

• 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.

NOTE: You may also return the PT-405 to the factory for repair and/or adjustment.



 IMPORTANT: Do not adjust Zero or Span potentiometer while your PT-405 is installed

in a Hazardous Location. Removing the protective screws to access the potentiometers
invalidates the Hazardous Location approvals until they are replaced.

• Repair and Returns

Should your PT-405 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.
