Model S-11 Flush Pressure Transmitter

Brand: WIKA Instruments

Specialist for Viscous and Solids-Containing Media The 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 conventional process connections.

Through its optimised design, the flush process connection enables the cleanability of the wetted diaphragm to be integrated into the process. Low-maintenance and troublefree pressure measurement is thus also guaranteed in critical applications with frequently changing media. High accuracy, a robust design, high-quality workmanship and the high flexibility of configuration are key features of the model S-11.

Flush Process Connection All process connections of the flush pressure transmitter are made of stainless steel, all welded and isolate the process 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 302 °F (150 °C), 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 in accordance with FDA 21 CFR 178.3750 can be chosen.
