PISTON PRESSURE SWITCH

We are known throughout Europe as a leading specialist for piston pressure switches and provide our customers with a broad range of pressure switch designs. Many years of experience with material combinations, processing techniques and production tolerances enable us to meet the most varied requirements in a targeted and flexible Our pressure switches are distinguished by their durable precision, a broad spectrum of applications and uncompromising reliability. The DS 507/502 is the "standard" pressure switch. It is, in common with the DS 307/302, precise and durable, but less variable. The broad...

TECHNICAL DATA 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

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 pressure....
