„
Serious injuries and/or damage can occur should the appropriate regulations
not be observed.
„
Only appropriately qualified personnel should work on these instruments.

2. Operating principle

Bourdon tube, diaphragm and capsule measuring elements are widely used
as measuring elements for such transmitters thanks to their robustness and
ease-of-use within technical pressure measurement. Under the influence of
pressure, these measuring elements will be deformed within their elastic range.
This movement is converted into a rotary motion by means of a mechanical
movement (gear). A magnet, fixed to the pointer axle, turns with the instru-
ment's pointer, in direct proportion to the process pressure. The connected
electronics detect the rotary motion of the magnet between 0 and 270 degrees.
A non-contact (and thus wear-reseistant), magnetic-field dependant sensor
(angular rotation sensor, 10 bit resolution) measures the change electrically.
An amplifier converts the rotary motion into an electrical output signal. The
electronics are factory set to a standard passive 4 ... 20 mA output signal,
(0 ... 20 mA, 0 ... 10 V and 4 ... 20 mA). The electrical output signal range
corresponds to the measuring range on the dial.
With these three standard electrical output signals, this series of instruments
can be used in all areas of industry.
A pressure gauge with a transmitter (multifunciontal gauge) combines all the
advantages of an on-site mechanical display with the demands modern industry
makes for electrical signal transmission for the acquisition of measured values.

The appropriate national safety regulations (e.g. EN 837-2
"Selection and installation recommendations for pressure
gauges") must be observed when installing, commissioning and
operating these devices.
