Operating Instructions
and resetting points...). Switching conditions and pressure values can be read off using the various
display elements.
This is a device of class B for emitted interference and is intended for operation in industrial envi-
ronments. In other environments, e.g. residential or commercial areas, it could interfere with other
devices under certain circumstances. In this case, the operating entity may be required to take
appropriate measures.
Only use the pressure switch in applications which are within its technical performance limits (e.g.
max. ambient temperature, material compatibility, ...).
→ For performance limits, see Chapter 9 "Technical data".
Technical restrictions
The overload pressure must not be exceeded at any time, even when faults in the end applica-
„
tion occur. Strains exceeding the overload protection can cause measurement errors.
Pressure surges above the nominal pressure and for less than 1 ms can cause measurement
„
errors.
The use of a choke is recommended for applications for which pressure peaks occur. The choke
„
restricts the pressure channel to 0.3 mm, thereby increasing the resistance to pressure peaks.
Alternatively, a process connection with reduced channel bore hole (0.3 mm or 0.6 mm) can be
used.
A flush-mounted device version must be used for measuring materials which could clog a
„
channel bore hole (e.g. particle board).
At high ambient temperatures and high UV radiation, the pressure switch must be installed with
„
additional shading to prevent damage to the digital display and pushbuttons.
The measuring material temperature in the device must not exceed 85 °C. A cooling line can be
„
helpful for hotter measuring materials.
