Pressure gauge in hygienic design with mounted diaphragm seal
Description
Diaphragm seal systems are used to protect the pressure measuring instrument from aggressive, adhesive, crystallising, corrosive, highly viscous, environmentally hazardous or toxic media. The diaphragm made of stainless steel provides for the separation from the medium. The pressure is transmitted to the measuring instrument via the system fill fluid which is inside the Diaphragm seal system.
The DSS22P complies with all requirements of the pharmaceutical industry. The particular suitability for pharmaceutical products rests on the fact that the measuring point can be cleaned while installed.
Special features
- Case and wetted parts in hygienic design
- Suitable for SIP and CIP
- Clamp connection easy to open for cleaning and seal replacement
- Easy zero point setting
