1. Safety instructions / 2. Measuring principle

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.

2. 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.
