Pressure gauge per EN 837-1 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 DSS22F complies with all requirements of the food industry. The particular suitability for foodstuffs rests on the fact that the measuring point can be cleaned while installed.
Special features
- Quick cleaning, without residue
- Clamp connection easy to open for cleaning and seal replacement
- Suitable for SIP and CIP
