    •                
The high precision of piezoresistive pressure sensors and their possible customization to specific requirements allow their versatile use in a wide range of applications.
Pressure sensors supply measured data for industrial equipment and systems in order to control and diagnose hydraulically or pneumatically operated machines, for instance. This makes them key components in measurement and control technology.
The portfolio of pressure sensors has been developed with a strong focus on increased sensitivity and high performance with long-term stability. In addition, particular attention is paid to specific features for media resistance and ease of processing.

Differential Pressure measurement transmitters

Differential pressure sensors measure the difference between two applied pressures. They are commonly used for application like flow measurement, filter monitoring or pump and valve monitoring.
