Absolute pressure sensors, M7, for measurements in gas and hydraulic systems (max 1000 bar) / 4065B
4065B
These compact high pressure sensor with robust diaphragm are suitable for pressure measurements in hydraulic systems (e.g. injection systems of combustion engines).
主要特点/优势
- For measuring static and dynamic pressure
- Minimal sensor dead volume, therefore high acoustic natural frequency
- High mechanical natural frequency
- Digital temperature compensation
In the pressure sensors of family Type 4065B, the pressure acts through a robust diaphragm onto a piezoresistive measuring element. The compact dimensions and the shoulder sealing of the pressure sensors provide ideal access to the measuring point. Only a minimal dead volume is created between the sensor front and the measured medium. The sensor is therefore suitable for applications with a high requirement for frequency-accurate pressure measurements. Zero point and sensitivity shift caused by temperature changes are corrected through the use of a digital temperature compensation without impairing the signal bandwidth. In addition, the digital temperature compensation provides a monitoring of the sensor temperature (with amplifiers of Types 4665B and 4624A).
