2 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.
2.1 Operating statuses
Operating status Function
RUN mode – Initial status after switching on the operating voltage
– Display of the current measured value
SHOW mode – Display of the current settings
EDIT mode – Setting or modification of parameters
TEACH mode – Acceptance of the current measured value to determine switching points
