SICK PBS plus Pressure Sensor – Added Versatility for Pressure Monitoring Installations

The PBS plus Pressure Sensors from SICK, expands upon their existing PBS Sensor range, they have been purposely designed for demanding industrial applications, providing an electronic pressure switch, pressure transmitter and display all-in-one, available with up to two switching outputs, analogue output and IO-Link communication.

PBS plus Pressure Sensor in actionSimple to set-up, the PBS plus features three large pushbuttons and an easy-to-read display and they can be set-up using IO-Link, which also provides diagnostic functions and simplifies predictive maintenance, external parameterisation also makes handling easier and ensures lower maintenance costs.


Easily adapted for countless installation possibilities

The PBS plus range of Pressure Sensors are easily adapted to suit numerous installations, for example, the housing can be rotated twice, once at the process connection and then at the display cap, meaning the electrical connection can be rotated in the desired direction at any time.

Versatile, thanks to the large number of available process connections, including a flush-mounted membrane for sticky, crystallising and viscous media, helps to widen the integration possibilities of the PBS plus Pressure Sensor series. 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.

PBS plus Pressure Sensor Applications

  • Measurement of system pressure in hydraulic systems
  • Control of the clamping pressure in CNC machines
  • Monitoring of the cylinder pressure in hydraulic presses
  • Control of the pressure in cooling and lubricant systems
  • Hydrostatic level measurement
  • Measurement of system pressure in PET bottle production



The best in challenging conditions

Whether in aggressive environments, with measuring ranges of 0.4 bar to 1,000 bar, or when used with viscous liquids, the PBS plus takes challenging environments in its stride. 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 the membrane. Temperatures between –20 °C and +85 °C are no problem for the PBS plus.

IO-Link? Bi-directional Data Exchange? What’s that?


IO-Link is an industrial communication network standard (IEC61131-9) that allows the easy extraction of data from process control and automation sensors that support the IO-Link protocol and are connected to a device master. IO-Link is the first globally standardised IO-technology that has been designed to allow communication from the primary controller down to a basic automation level.

Linking together

How do you connect your IO-Link devices together? It couldn’t be easier or more cost effective for you to create an effective IO-Link network. Standard, unshielded 3 or 4 core cable and a standard port with M5, M8 or M12 connectors is all that you need to connect a network of digital and even analogue actuators and sensors to your master unit.

The master device, such as the Baumer Wireless IO-Link Master, can transmit the data it has accrued from numerous sensors over integrated WLAN and Bluetooth, other devices may use communication protocols like Industrial Ethernet or PROFINET. This data can be utilised for process monitoring by PLC’s, computers and HMI’s or can be used to facilitate immediate corrective action if the process is under threat. Being an open standard, IO-Link devices versatility and adaptability means they can be integrated into virtually any industrial process and control system that you can imagine

Intelligent enabler

IO-Link technology enables you to save device-specific parameter data directly in the IO-Link master which makes the installation and the exchange of like for like sensory and process control devices that much easier, saving you time, money and reducing any potential errors from entering the process.

Each sensory device connected to the master has an allocated IODD (IO Device Description) where technical data is stored concerning its functionality and manufacturing information. Accessibility to the individual sensors at source isn’t required as all of its technical data is stored within the master and can be accessed from your control point.

The seamless communication from the smart sensor to the master and then to the Internet is essential for fast, flexible and reliable production control processes and insight, and is a perfect accompaniment to Industry 4.0 applications.  Devices such as the Baumer Wireless IO-Link Master mentioned previously, can be easily accessed by smartphones and other internet and enabled devices allowing you to monitor your processes from anywhere in the world.

Advantages of IO-Link at a glance:

  • Overall reduced costs – no special wiring required
  • Increased process efficiency –access to all sensory level data, remote configuration and monitoring
  • Easy to replace – existing devices can be exchanged like for like with no lengthy setup times
  • Diagnostics – IO-Link provides users with visibility into errors, performance and health status of connected devices
