The PS+ series pressure sensor is a fully programmable pressure sensor that offers a local display as well as electrical outputs to provide critical feedback to a control system.

The sensor features:

  • A stainless steel measuring cell for pressure ranges >10 bar
  • Up to 600 bar relative pressure
  • Accuracy up to 0.25%
  • IO-Link 1.1
  • Automatic signal detection
  • Up to seven-fold overpressure resistance
  • High protection class (IP6K6K, IP6K7, IP6K9K)
  • 180° invertible multicolour display
  • Rotatable sensor body

Conventional applications

The pressure sensors of the PS+ series enable the reliable and reproducible measurement of process pressures in industrial applications. The large number of different pressure ranges and process connections results in a wide range of variants, ensuring simple application.

Pressure sensors are very frequently used in the following application fields:

  • Hydraulic applications
  • Cooling circuits
  • Lubricant applications

Higher system availability

The stainless steel housing in conjunction with the single-piece cover is an extremely robust design. The absence of mechanical operating elements ensures a high wear resistance. The reduced number of sealing surfaces offers maximum protection from humidity and dust penetrating inside the device — even outdoors thanks to the materials resistant to UV radiation and salt spray. The new sealing concepts enable protection classes IP6K7K, IP6K7 and IP6K9K. The PS+ series also offers exceptional resistance to vibration and shock. The measuring cells of the PS310 series have a burst pressure of at least four times the maximum nominal pressure, while the PS510 series features up to seven times maximum nominal pressure. The minimum/maximum pressure memory forms a digital ‘drag pointer’, making a better analysis of processes possible.

Simple operation

The pressure switch points can be set in a few steps in the usual way, either according to the Turck or VDMA standard. The 14-segment display offers users optimum support in navigating the menus.

The display can show process values in red or green giving operators a quick and easy way of determining whether the pressure is within the normal operating range.

The colour change can be linked here to the switching outputs in order to indicate the actual switching status via the switch point LEDs.

Advanced functions

The advanced functions enable the sensor to be reset to its previous settings (Undo function) as well as to the factory settings. The switching behaviour of the outputs can be set to NO and NC. Additional hysteresis and filter functions enable the optimum adaptation of the sensor for complex applications.

Simple mounting and commissioning

The PS+ Series offers a variety of useful features to make mounting, connection and commissioning of the sensors as effective and straightforward as possible:

  • The large selection of different process connections ensures a simple connection to the process environment.
  • The freely rotatable sensor housing allows the display and plug connector to be aligned after mounting.
  • The automatic detection of output signals simplifies the connection to the controller environment.
  • The option of either Turck standard or VDMA menu guidance ensures intuitive operation of the sensor.
  • The different IO-Link process data profiles enable the sensor to be adapted to existing systems and thus reduce the programming effort required.

Multicolour display

The display can show all indicated information in green or red. This makes it possible to optimally adapt the device to the particular lighting conditions of the application. Several setting options also allow the display colour to be linked to the status of the sensor switching outputs.

Automatic signal detection

Devices with an analog output automatically detect whether the connected interface expects a current or voltage signal. This automatic setting of the analog output reduces configuration time and helps to prevent errors.

Variable data mapping

IO-Link process data profiles enable the flexible connection of the sensor with a large degree of freedom. This allows convenient adaption to existing systems with a 1:1 replacement of existing devices — even from third party manufacturers. This eliminates the need for complex adaptions to the controller environment.

Maximum robustness

The IP protection classes 6K6K, 6K7 and 6K9K, excellent resistance to shock and vibration, as well as a high pressure resistance ensure increased system availability. The design without mechanical pushbuttons also minimizes the number of sealing surfaces required.
