CAUTION

PRODUCT DAMAGE DUE TO MECHANICAL ISSUES

• Ensure torque specifications are determined for the specific application. Values provided are for reference only. (Mating

materials and thread sealants can result in significantly different torque values from one application to the next.)

• When using mating parts made of stainless steel, use a thread sealant with anti-seize properties to prevent thread galling.

Ensure the sealant is rated for the application.

• Use appropriate tools (such as an open ended wrench or deep well socket) to install transducers.

• Always hand-start transducers into the hole to prevent cross threading and damage.

• Ensure that torque is not applied to the electrical connector.

• Ensure that the proper mating electrical connector with a seal is used to connect the transducer. Improper or damaged seals

can compromise ingress protection, leading to short circuits.

Failure to comply with these instructions may result in product damage.

CAUTION

PRODUCT DAMAGE DUE TO PARTICULATES

• Ensure that a filter is used upstream of the transducer to keep media flow free of larger particulates and increased humidity. All

PX2 Series transducers are dead-ended devices; particulate accumulation and condensing moisture may affect sensor output.

• It is recommend that the transducer be positioned with the port facing downwards; any particulates in the system are less

likely to enter and settle within the pressure transducer if it is in this position.

• Ensure that the media does not create a residue when dried. Build-up inside the transducer may affect transducer output;

rinsing of a dead-ended transducer is potentially difficult and has limited effectiveness in removing residue.

Failure to comply with these instructions may result in product damage.
