6 Function
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 eval-
uation unit. Connection 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 differ-
ential pressure. For each output, PNP or NPN and normally open (NO) or normally
closed (NC) can optionally be set. Through the IO-Link interface, process values
can be read out and parameters changed and transmitted to additional devices.
