1. Safety instructions
The relevant national safety provisions (e.g. VDE 0100) must be
observed when mounting, putting into commission and operat-
ing this pressure transmitter. Severe injuries and/or damage
might occur as a result of non-compliance with the correspond-
ing provisions. Only qualified personnel is authorised to work on
these instruments.
Please observe the following operating parameters
The pressure transmitter is exclusively suitable for dry, clean,
non-aggressive gases.
Do not blow into the process connections!
The measuring cell might be damaged by the respiratory
pressure.
Max. medium/ambient temperature: 10 ... 50 °C
It has to be made sure that during transportation both
process connections are open. Instruments with absolute
pressure measuring ranges must be transported in pressure
compensation cabins.
. Measuring principle
The pressure mesurement is realised via a sensitive diaphragm or, in the case of
absolute pressure measuring ranges, a capsule which is adapted to the measuring
range. An inductive system generates a linear signal which changes in proportion to
the prevailing pressure.
