TECHNICAL DATA General information 1 special low-friction seal SERVICE LIFE The service life of a piston pressure switch depends on numerous factors. Minimum and maximum pressures, cycle rate, load change, hydraulic vibration, the load (amp.) on the electrical switch, etc. Where a pressure switch needs to meet special requirements, we are in a position to address the most varied requirements in a flexible and targeted manner, thanks to our years of experience with material pairings, machining processes and production tolerances. The pressure switches must be installed so that the device is not...

HYDRAULISCHE ERZEUGNISSE GMBH & CIE. KG 1. Standard seal (normal version): The hysteresis achieved during continuous operation is approx. 7-12 % of the final value at a set pressure of approx. 60-70 % of the max. adjustable switching pressure. Example: In the case of a DS-507-100 pressure switch with a pressure range of 10-100 bar, a hysteresis of approx. 7-12 bar is achieved at a set pressure of 70 bar. 2. Special low-friction seal (SS design) The hysteresis achieved during continuous operation is approx. 3-6 % of the final value at a set pressure of approx. 60-70 % of the max. adjustable switching...
