Pressure switch PBS with IO-Link

The PBS is an electronic pressure switch, pressure transmitter and display in one. It is available with up to two switching output, analog output and IO-Link in a single device.

Its intuitive configuration via three large pushbuttons and display facilitates operation. The housing can be rotated in two ways. This means that the display and electrical connection can be aligned to match the specific installation situation.

The PBS can be utilized in a wide range of applications due to its gauge pressure measuring ranges between 0 bar – 1 bar and 0 bar – 600 bar. In addition, absolute pressure and compound measuring ranges are available.

The PBS features a fully welded stainless steel membrane, making it suitable for use with a host of corrosive media. Numerous standard process connections make adapters redundant in most cases. In addition, a flush-mounted membrane is available for pressure measurement in heterogeneous liquids.
