Application areas
Only use the pressure transmitter/switch in applications that lie within its technical performance limits (e.g. max.
ambient temperature, material compatibility, etc.).
Technical restrictions
The overload pressure must never be exceeded, even when failures occur in the end-use application. Loadings
above the overload safety can cause measuring errors.
Pressure surges below the nominal pressure and shorter than 1 ms can cause measuring errors.
For applications where pressure spikes can occur, the use of a restrictor is recommended. The restrictor narrows
the pressure port to 0.3 mm and thus increases the resistance against pressure spikes.
With a high ambient temperature and a high UV irradiation, the pressure transmitter/switch must be installed with
additional covering in order to avoid damage to the digital indicator and buttons.
The medium temperature at the instrument must not exceed 185 °F (85 °C). With hotter media, a cooling element
can provide a solution (see chapter 10 “Accessories and spare parts”).
3.3 Personnel qualication
Skilled personnel
regulations, current standards and directives, are capable of carrying out the work described and independently
Special operating conditions require further appropriate knowledge, e.g. of aggressive media.
