Electronic pressure-gauge station

Operation

A piezoresistive pressure sensor produces a pressure-proportional bridge voltage.   This voltage is normalised to the corresponding measuring range and is usable as 4-20 mA-signal.

Installation instructions

Pressure transducers should not be subjected to me-
chanical vibrations, wall-mounting is recommended.

To achieve sufficient cooling respectively heating of the
fluid, the connection between pipeline and pressure
sensor should be made by a ring syphon.
In case of extreme high or low temperatures it is re-
commended to install a sufficiently long piping.
