Description
Specialist for viscous and solids-containing media
The model S-11 pressure transmitter with ush diaphragm
has been specically 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 conguration 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.
Specically for the food and beverage industry, a version
with internal system ll uid in accordance with FDA 21 CFR
178.3750 can be chosen.
