A basic requirement to control various functions in mobile machines is the pressure measurement in hydraulic circuits. There is often not enough space to measure the pressure by using a pressure senor. With the BODAS PR4 sensor, Bosch Rexroth offers a compact pressure sensor with a variety of advantages and easy assembly for use in the field of mobile hydraulics. The sensor signal can be analyzed immediately by a BODAS RC controller or other control units. The BODAS pressure sensor PR4 is suitable for use in almost any mobile working machine – be it in the area of construction machines, agricultural machines or material handling applications.
