Notes on Spare Parts Selection

  • Confirm the transmitter model and spare part compatibility, e.g., some spare parts are common between PTP31B and PMP series.
  • Pay attention to process connection standards (e.g., G1/2, NPTF1/2) and installation requirements.
  • Material certification (e.g., EN10204-3.1) is crucial for special operating conditions.
  • Cable plug length and angle (straight or 90-degree) should be selected based on on-site space.

Correct selection can reduce downtime and improve maintenance efficiency. It is recommended to refer to the official spare parts list and combine it with actual operating conditions.
