Flexible Diaphragm Seal Solutions

The PMP63B can be equipped with different diaphragm seal configurations, making it suitable for processes where the pressure transmitter needs additional protection from the process medium.

For demanding temperature conditions, diaphragm seal configurations can support process temperatures up to 250 °C. The device is also available with Contite technology, which provides enhanced resistance to condensation and helps protect the measuring cell in challenging process environments.

One Transmitter for Pressure and Hydrostatic Level

The PMP63B is designed to measure both pressure and hydrostatic level, providing flexibility when the same measurement principle needs to be applied across different process applications.

Typical applications include:

• 
  Hydrostatic level measurement
  
• 
  Absolute pressure measurement
  
• 
  Gauge pressure measurement
  
• 
  Process pressure monitoring
  
• 
  Pressure measurement in liquids and gases
  
• 
  Applications requiring diaphragm seals
  
• 
  Hygienic process applications
  

Modern Communication and Digital Integration

The PMP63B supports several communication technologies depending on the selected configuration. Available interfaces include 4–20 mA HART, PROFINET over Ethernet-APL and PROFIBUS PA.
