Description
This sensor serves for the measurement of pressure in hydraulic circuits. It is especially suited for use in mobile hydraulics due to
its excellent features. Shock and vibration resistance, type of protection, resistance to pressure peaks, resistance to temperature
shock, EMC characteristics (up to 100 V/m). The measuring principle uses a hermetically welded thin film measuring cell which
provides long-term density. The sensor signal can be directly analyzed by a BODAS controller RC.
