RESET DIFFERENTIAL PRESSURE 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...
