Applications for this product

• Hygienic pressure measurement
• Production plants for the food and pharmaceutical industry
• For use in UHT plants and separators
• For the monitoring of processes with sterile steam

Features of this product

• Compact design with flush diaphragm
• Materials suitable for contact with food
• Clamp connection easy to open for cleaning and seal replacement.
• Suitable for SIP and CIP
• Latest IO-Link specification: Version 1.1

The model DSSA11SA compact diaphragm seal system is particularly well suited for hygienic process integration in sanitary applications. The model DSSA11SA meets the requirements of CIP (Cleaning in Place) and SIP (Sterilization in Place) and withstands the temperatures of the cleaning steam.

The clamp connection (TRI-CLAMP®) enables quick and easy dismounting and thus a simple cleaning with seal replacement. In the basic version, the instrument is fitted with a pressure sensor without a display, which, depending on the application, can be used either for pressure monitoring or as an electronic PNP/NPN switch for process control.

With an additional IO-Link interface, the instrument can be programmed flexibly and has integrated diagnostic functions that monitor the instrument's status. In addition, this allows the digital signal to be configured externally and conveniently at any time. This version, which has been enhanced with a 360° LED status indication, provides visual information about the status and enables intuitive and quick error detection and correction. For maintenance, a blinking function via IO-Link facilitates the clear localization of a diaphragm seal system. The blinking function prevents confusion of measuring locations and accelerates maintenance.
