Application

The pressure transducers are suitable for measuring static and dynamic liquid
and gas pressures. They are available in various measuring ranges, graded
from 1 to 3000 bar and with various electrical connection options (see Chapter
10 "Options").
All liquids and gases (vapors) that do not corrode the steels given in the spe­
cifications are a suitable measurement medium. The pressure transducer is
attached by its threaded connection piece for the pressure connection and can
be mounted in any position. In the individual case, follow the actual instructions
given in Chapter 4 "Installation".

Structure and mode of operation

Transducers with the 0..10 bar and 0...3000 bar measuring ranges work
according to the strain gage principle.
With the 10 to 3000 bar transducers, the internal measurement tube carries the
the strain gages, which are interconnected to a Wheatstone bridge.
The strain gage application is located on the side of the tube away from the
measurement medium in a hermetically sealed reference chamber. This
protects it from environmental influences.
The transducer housings are made from stainless steel and hermetically seal
the measurement system to protect it against any harmful external influences,
so that even if the operating conditions continue to be rough, the reliability and
precision of the transducer are not impaired.
The parts of the up to 200 bar transducers that come into contact with the
media consist of 1.4301 and 1.4542 stainless steel. With the P3/500 bar to P3/
3000 bar type series, they are made of 1.4542 stainless steel.
