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 Fig. 3 2.2 Switching functions Threshold value comparator for monitoring of a pressure threshold Function NO (normally open) NC (normally closed) Switching function: – 1 Switching point (SP) TEACH mode: – 2 teach-in points (TP1, TP2) – SP = ½ (TP1+TP2) TP1 TP2 HY 1 0 Out p SP TP1 TP2 SP HY 1 0 Out p Fig. 4 Window comparator for monitoring of a pressure range Function NO (normally open) NC (normally closed) Switching function: – 2 Switching points (SP.Lo, SP.Hi) TEACH mode1): – 2 teach-in points (TP1, TP2) – TP1 = SP.Lo, TP2 = SP.Hi HY HY TP1=SP.Lo TP2=SP.Hi 1 0 Out p HY HY TP1=SP.Lo TP2=SP.Hi 1 0 Out p 1) SP.Lo = smaller pressure/vacuum value, SP.Hi = larger pressure/vacuum value, dependent on the Teach sequence Fig. 5
