2 Safety
Intended use
The pressure sensor SPAN is intended for monitoring pressure of compressed air
and inert gases in the piping.
General safety information
 Only use the product in its original status, without any unauthorised modifications.
 Only use the product if it is in an excellent technical status.
 The product is intended for use in industrial environments. Measures may need
to be implemented in residential areas for radio interference suppression.
 Take into consideration the ambient conditions at the location of use.
 Operate the product only with compressed air of the specified air quality class
(è Technical data).
 Observe the specifications on the rating plate.
 Comply with all applicable national and international regulations.
Disposal
 Observe the local specifications for environmentally friendly disposal.
3 Function and application
The sensor converts pneumatic pressure values (relative pressure) into electrical
signals, 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 optional analogue output and an optional IO-Link interface.
The switching outputs can be configured for monitoring of a threshold value,
a pressure range or a differential pressure. The outputs can be set as PNP or NPN
and normally open (NO) or normally closed (NC). Via the IO-Link interface, process
values can be read out and parameters changed and transmitted to additional
devices.
3.1 Operating statuses
Operating status Function
RUN mode – Basic status after the operating voltage is switched on
– 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 d_|¯|_
This funciton permits monitoring of a pressure value for constancy.
If the applied pressure is constant in the range between [SP.Lo] and [SP.Hi], the refer
ence pressure PRef is automatically determined. The result is a switching operation at
the output. The signal change signals the start of pressure monitoring.
If the pressure remains in the monitoring range [d.SP] around PRef, the pressure is
stable. When the monitoring range is left (e.g. caused by a leakage in the system),
the output switches back.
