Description

The WIKA combination of diaphragm seal, pressure measuring instrument and monitoring instrument is ideally suited for the harshest measurement tasks. The system can withstand aggressive, contaminated or hot media and ensures a secure connection between the medium and the diaphragm monitoring system.

The patented diaphragm monitoring has been designed specifically for the highest safety requirements in the chemical and petrochemical industries. Through the diaphragm monitoring, the risk of an unnoticed rupture of the diaphragm is avoided, since this is immediately indicated on the monitoring instrument. In addition, an electrical signal can be transmitted to the system control.

In the event of a diaphragm rupture, a second diaphragm in the pressure measuring instrument ensures the reliable separation of the environment and the process.

Mounting of the diaphragm seal to the pressure 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 monitoring systems with the WIKA model 990.27 diaphragm seals are used successfully in applications with hydrofluoric acid content.
