Pressure sensor and pressure transmitter SPAU
Maximum fl exibility!
Intelligent pressure
measurement
The SPAU is an intelligent
pressure sensor with a freely
programmable threshold value or
window comparator. It has a wide
range of functions for non-
corrosive gases comprising:
• Network monitoring
• Regulator monitoring
• Vacuum monitoring
• Leak tests
• Object detection
Remote maintenance and
parameterisation as well as
simple sensor change are also
possible via IO-Link.
Unique fl exibility
The unique fl exibility of the
pressure adapter guarantees
quick and easy mounting in all
installation scenarios. For
example, the pressure outlet
direction can be freely selected
via a modular system at the back
and at the bottom and the plug
outlet direction M8/M12 can be
selected at the top, bottom and
at the back. Furthermore, the
switchable PNP/NPN current and
voltage outputs make it possible
to adapt to all control systems.
Easy operation
Thanks to a large, easy-to-read,
blue/red LCD display, it is
immediately apparent whether
the pressure is OK.
Clear 3-key menu navigation:
quick to start up and easy to
teach via pressure switch point
setting.
Sturdy design
The IP65 design enables it to be
used in harsh environments.
The sensor SPAU for pressure measurement, pressure monitoring
and pressure sensing keeps pressure levels permanently under
control, ensuring more productivity and process reliability. As well
as quicker system commissioning.
