Applications
* Machine tools
* Hydraulics and pneumatics
* Automation engineering
* Special-purpose machine building
Special features
* Industry 4.0-ready IO-Link sensor improves connectivity and diagnostics
* Designed for rough demands of up to 1,000 g shock and -40 ... +125 °C [-40 ... +257 °F]
* Optimised design makes OEM machine integration easier
* Multicolour 360° LED status display simplifies troubleshooting and localisation

* The given measuring ranges are also available in kg/cm², kPa and MPa.

* Special measuring ranges between 0 ... 0.4 and 0 ... 1,000 bar [0 ... 10 to 0 ... 15,000 psi] are available on request.

* Special measuring ranges have a reduced long-term stability and higher temperature errors.

Overload safety: The overload safety is based on the sensor element used. Dependent on the selected process connection and the sealing, restrictions in overload safety can result.

     Measuring range ≤ 600 bar [< 8,000 psi]: 2 times

      Measuring range > 1.000 bar [≥ 8,000 psi]: 1.5 times

Increased overload safety (option): With increased overload safety there are deviations in temperature error and long-term stability.
