Function and application
The pressure sensor SPAU is intended for monitoring pressure in the piping.
The
sensor converts pneumatic pressure values (relative pressure) into electrical sig
nals, which can be used for control or regulating functions.
Measurements are
carried out using a piezoresistive sensor element with a following electronic evalu
ation unit. Interfacing to the higher-level system is provided by 1 or 2 switching
outputs, an analogue output and/or an IO-Link interface.
The switching outputs can be configured for monitoring of a threshold value, a
pressure range or a differential pressure. For each output, PNP or NPN and nor
mally open (NO) or normally closed (NC) can optionally be set. Via the IO-Link inter
face, process values can be read out and parameters changed and transmitted to
additional devices.
