  • Hygienic pressure measurement for the pharmaceutical industry and for aseptic food processing
  • Pressure/vacuum measurement on pipelines, fermenters, bioreactors and vessels as well as with processing and transport of high-quality media
  • Suitable for the production of active pharmaceutical ingredients (API)
  • For gases, vapour; liquid, pasty, powdery and crystallising media

Special features

  • Double-diaphragm system to ensure the separation of the process and the pressure measuring instrument (patent, property right: DE102016015447A1) Process connection with flange to provide for direct threaded connection
  • Clamp connection easy to open for cleaning and seal replacement
  • Suitable for SIP and CIP


The WIKA combinations consisting of diaphragm seal, pressure measuring instrument and monitoring element are best suited for the harshest and hygienic measuring tasks. The systems can withstand the cleaning vapour temperatures occurring in the SIP processes and ensure a sterile connection between the medium to be measured and the diaphragm seal.

The patented diaphragm monitoring has been designed specifically for the highest safety requirements in the pharmaceutical and biotechnology industries. The monitoring element is mainly used for electrical signal transmission of the diaphragm condition. In addition, the diaphragm condition is displayed on a dial with red/green areas.

In the event of a diaphragm rupture, a second, internal diaphragm in the pressure measuring instrument ensures the reliable separation of the environment and the process.
Mounting of the diaphragm seal to the measuring instrument is made as direct mounting as standard. A fluid inside the system, which is explicitly chosen to suit the particular application, hydraulically transmits the pressure to the pressure measuring instrument.

Diaphragm seals with clamp connection have been specifically developed for use in sterile processes and are integrated into the process by means of a clamp. This ensures the hygienic process integration of the diaphragm monitoring system.
