Description
Reliable
The WU-2x series combines state-of-the-art digital transducer
concepts with analogue-like output signals, in order to provide
the safest and most accurate pressure measurements
necessary for today’s market requirements.
Pressure measurement, based on a true vacuum reference,
and electronic measures for interference shielding and
signal noise cancellation ensure high-accuracy pressure
measurement and excellent long-term stability.
Active temperature compensation reduces the impact of
changing temperatures on the transducer, allowing safe
operations even in applications with high fluctuations in
temperature, e.g. Joule-Thomson effect in the case of gas
expansion.
WU-25 (flow through) and WU-26 (surface mount)
transducers are specifically designed to sustain torsionapplied
stresses often incurred during installation. The
special design of the thin-film sensor eliminates the risk of
sensor failure due to loads at the process connection or
welded joints.
