Description

Specialist for viscous and solids-containing media

The model S-11 pressure transmitter with ush diaphragm
has been specically 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 ush 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 exibility of conguration are key features of the

model S-11.

Flush process connection

All process connections of the ush 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.

Specically for the food and beverage industry, a version
with internal system ll uid in accordance with FDA 21 CFR

178.3750 can be chosen.
