CAUTION
PRODUCT DAMAGE
• 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 TO TUBE PORT
Ensure that the temperature of the brass port and plastic connector is maintained below 125 °C during flame brazing. Exposure
to temperatures higher than 125 °C can cause permanent product damage and can compromise ingress protection leading to
short circuits.
Failure to comply with these instructions may result in product damage.

Diagnostics Mode
The PX3 Series diagnostics mode allows the device to indicate
when internal or external faults occur. If an internal fault occurs,
the output will rail to the preset lower or upper limit values shown
in Figure 3 and Table 6.
External faults will result in the sensor’s output exceeding those
preset limits (lower or upper). (For example, if the external sensor
ground (signal) were lost, the sensor output would exceed the upper rail of 97.5%.)
