The PBS plus is an electronic pressure switch, pressure transmitter and display in one and is available with up to two switching outputs, analog output and IO-Link. It is set using three large pushbuttons and the display or via IO-Link. The housing can be twisted in two places - the display and the electrical connection can be optimally aligned in any mounting situation. With measuring ranges of 0.4 bar to 1,000 bar (gauge pressure), the PBS plus can be used in many different applications. It also has absolute pressure and vacuum measuring ranges. The PBS plus is highly resistant to corrosion due to the fully-welded stainless steel membrane. Process data is transmitted to the control via IO-Link as measured values in bar. The diagnostic options make it possible for temperature values to be read out in °C and minimum and maximum values for temperature and pressure to be monitored.

Sensor solutions for pneumatic and hydraulic systems
Fluid power sensors from SICK perform measurement tasks in pneumatic and hydraulic systems – intelligently, flexibly and reliably.
Lots of functions at a low cost: Measuring transducer, switch, display, logic and Industry 4.0 connectivity in one device
The PBS plus pressure switch has been designed with regard to optimum functionality and range of use. The result: A wide range of setting options reduces the number of sensor variants required within a production process, which in turn reduces potential warehousing costs for customers. For example, with the practical switchover function, you can determine on site at the sensor whether a PNP or NPN switching signal is to be output or whether a current or voltage output is required with the analog signal.
Thanks to its versatile functions, one and the same version of the PBS plus is suitable for many different applications. This effectively reduces effort and costs for warehousing.
High flexibility during integration
The PBS plus can be completely adapted to the respective application and installation situation on site. For example, the housing can be rotated twice – at the process connection and at the display cap. This means the electrical connection can be rotated in the desired direction at any time. The display can also rotate 180°. This allows integration into almost any machine design, and good accessibility of the display and the setting elements is ensured. In addition, the large number of available process connections, including flush-mounted membrane for sticky, crystallizing and viscous media, increases the integration possibilities of the PBS plus.
Suitable for a wide range of machine designs: The PBS plus is flexible and can adapt to any installation situation.
Made for challenging conditions
Whether in aggressive environments, with high pressures up to 1,000 bar or viscous liquids, the PBS plus is very comfortable in challenging environments. Due to the integrated electrochemical cell with fully welded stainless steel membrane, it can withstand even aggressive media, as no sealing medium is required between the electrochemical cell and membrane, which can potentially be attacked. Media temperatures between –20 °C and +85 °C are also no problem for the PBS plus. This ensures very high reliability for switching operations as well as pressure measurement.
Constant performance during operation: The PBS plus ensures very high process reliability in applications with demanding measurement conditions.
