S-11 Pressure Transmitter

The WIKA model S-11 pressure transmitter with flush diaphragm has been specifically designed for the measurement of viscous, paste-like, adhesive, crystallising, particle-laden and contaminated media, which would clog the pressure channel of standard process connections.

Through its optimised design, the flush process connection enables cleanability with the wetted diaphragm integrated into the process. Low-maintenance and trouble-free pressure measurement are thus also guaranteed in critical applications with frequently changing media.

High accuracy, robust design, high-quality craftmanship and the high flexibility of configuration are key features of the model S-11.

All process connections of the flush pressure transmitter are made of stainless steel and are fully-welded and isolate the medium from the pressure measuring instrument via a positive seal. A reliable, dead-space free sealing between the process connection and the measuring medium is thus assured.

For high medium temperatures of up to 150 °C (302 °F), the pressure transmitter is also available with an integrated cooling element.

Specifically for the food and beverage industry, a version with internal system fill fluid by FDA 21 CFR 178.3750 can be chosen.
