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

Auto difference monitoring
With the auto difference monitoring function, a change in pressure from a refer
ence value is detected. As a result, a maximum permissible pressure drop can be
monitored, for example.
If the input variable is in the work range between [SP.Hi] and [SP.Lo] and is con
stant, its value is set automatically as the reference value P
Ref
. The output
switches.
A constant input variable is present if the signal change is less than 0.2 % FS dur
ing the set observation time [t.obs].
The parameter [d.SP] establishes the permissible deviation of pressure from the
reference value and thus the monitoring range. If pressure exceeds or falls below
[d.SP], the output switches back.
Function NO (normally open) NC (normally closed)
Switching function:
– 2 switching points (SP.Lo,
SP.Hi) for setting the valid
work range
