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 exposed to damaging vibrations during operation and eventually cause a failure. The use of suitable damping materials can
significantly extend the service life.
Reset Differential Pressure
Standard seal (normal version): The hysteresis achieved during continuous operation is approximately. 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 an SG307-F-150 pressure switch with
a pressure range of 20-150 bar, a hysteresis of approx. 10,5-18,0 bar is achieved at a set pressure of 105 bar. These values
depend, of course, on the temperature and viscosity of the operating medium. The pressure range with different piston diameters
also influences these values
