3. Operating conditions
All values apply at a mean ambient temperature of max. 40 °C and for the ambient ratings according
■
to SN 29500 standards.
The case of the pressure transmitter is undamaged.
EN ■
The pressure transmitter is not exposed to strong vibrations.
■
The process connection is suitable for the measuring range.
■
The wetted parts are suitable for the medium.
■
For safety applications, hydrogen is not permissible as a medium.
■
No pressure peaks.
■
No static pressures are higher than the values indicated in the data sheet.
■
Use a shielded cable grounded at least at one end.
■
The maximum measured error of -3.5 ... +10 % of span must be considered.
■
A measured value of < 3.8 mA and > 20.5 mA has to be interpreted as an error signal by the logic
■
unit.
The pressure transmitter is only suitable for pressure measurement in applications where the
■
pressure values change dynamically.
For the process industry, the following applies in addition:
Electromagnetic environment in accordance with EN 61326-1:2006, EN 61326-2-3:2006 and
■
EN 61326-3-2:2008.
Deviation to EN 61326-3-2:2008: Frequencies below 100 kHz not tested according to IEC 61000-4-6.
■
For machine-building applications, the following applies in addition:
Electromagnetic environment in accordance with EN 61326-1:2006, EN 61326-2-3:2006 and
■
EN 61326-3-1:2008.
In accordance with EN 61326-3-1:2008, for testing in accordance with IEC 61000-4-5, a test level
■
of 2 kV is required. The interference immunity of the IS-3 is 1 kV. To achieve a higher interference
immunity, external protective measures must be provided.
