Product Description

WIKA    DSS22F   is a sanitary diaphragm sealed pressure gauge that complies with the EN 837-1 standard, making it ideal for the  food,  beverage, pharmaceutical, and biotechnology industries where sanitary pressure measurement is crucial. It  integrates  stainless steel diaphragm seals with precision pressure gauges, providing reliable mechanical  pressure display for CIP  (cleaning in place) and SIP (sterilization in place) processes.

The diaphragm sealing system is used to protect pressure measuring instruments from corrosive, viscous, crystalline,   corrosive, high viscosity, environmentally harmful or toxic media. A diaphragm made of stainless steel is used  for  separating from the medium. The pressure is transmitted to the measuring instrument through the system  filling fluid  inside the diaphragm sealing system.

Key Design & Features

• All-welded 316L (1.4435) stainless steel construction — crevice-free, no dead space, zero contamination risk.

• Clamp connection (Tri-Clamp®) — quick disassembly for easy cleaning, inspection, or diaphragm replacement.

• Flush diaphragm design — Ra ≤ 0.76 μm surface finish for residue-free cleaning.

• FDA-approved fill fluid (medicinal white mineral oil) — safe for food contact and sterile processes.

• IP65 protection — dust-tight and resistant to washdown environments.

• Fully compliant with CIP/SIP — withstands high-temperature sterilization and chemical cleaning agents.

Special features

• Quick cleaning, without residue.

• Clamp connection easy to open for cleaning and seal replacement.

• Suitable for SIP and CIP.

Applications

• Hygienic pressure measurement in sanitary applications for the food and beverage industry.

• Mechanical pressure display on pipelines and vessels.

• Pressure/vacuum monitoring during cleaning, sterilisation, pressure testing.

• For gases, vapour; liquid, pasty, powdery and crystallising media.
