Differential pressure sensor Deltronic

Temperature and pressure under control

The differential pressure sensor continuously monitors oil filters in hydraulic systems. At the same time, it controls the oil temperature. The sensor is available for different pressure and temperature ranges.

Technical information

Accurately measure low differential pressures at high system pressures. The differential pressure sensor Deltronic was developed for efficient and long-term stable differential pressure measurement. Thanks to the mechanical differential pressure monitoring, the sensor can be used at very high and non-stable system pressures.

Service

How is the product maintained?

We recommend an annual recalibration and adjustment for all our sensors to be able to guarantee the exact functionality. We calibrate our sensors with state-of-the-art measurement technology in our in-house calibration laboratory. Our test equipment is one of the most accurate references in measurement and control technology. The test results are summarised in a factory calibration certificate in accordance with DIN EN ISO/IEC 17025:2018-03.
