Flush pressure transmitter For viscous and particle-laden media WIKA data sheet PE 81.02 Applications ■ General industrial applications ■ Food and beverage industry ■ Filling and packing machinery ■ Many configurations possible ■ Flush process connection ■ Large stocks for short delivery times Fig. left: Pressure transmitter model S-11 Fig. right: Pressure transmitter model S-11 with cooling element Expert for viscous and particle-laden 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 cleanability with the wetted diaphragm integrated into the process. Low-maintenance and trouble-free 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 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 in accordance with FDA 21 CFR 178.3750 can be chosen. ^ Part of your business WIKA data sheet PE 81.02 • 09/2017 Data sheets showing similar products: High-quality pressure transmitter for general industrial applications; model S-20; see data sheet PE 81.61 Pressure transmitter for applications in hazardous areas; model IS-3, see data sheet PE 81.58 Pressure transmitter for highest pressure applications; model HP-2; see data sheet PE 81.53

1) The existence of strong electromagnetic fields in a frequency range of < 2.7 GHz can result in increased measuring errors up to 1 %. Do not install the instruments in the vicinity of strong electromagnetic sources of interference (e.g. transmitting devices, radio equipment), or use sheath current filters where applicable.
