Analysing delay of pressure switch
When pressure switch Settings, take into account the technological requirements of pressure range and field measured pressure pulsation, otherwise if not considering these two points, it is easy to cause large hysteresis values.
Due to the lag of pressure switch itself, when pressure switch is used more or less will be back to the poor, namely pressure hysteresis: when to set value by calibration pressure, pressure switch, not only when the pressure changes after part of the pressure switch to action, from low to high pressure, then from high to low the pressure difference between the two action points is called hysteresis.Pressure switch before leaving the factory, therefore, have to pass strict calibration, if there is a repair internal institutions can be properly repaired, it is qualified, otherwise the production of pressure switch is not qualified.
Delay of pressure switch itself and it has the hysteresis of setting range is different, can't set itself with hysteresis sex, and return difference value is small, the hysteresis of pressure switch has set the scope is to meet the technological requirements and set value.
The above:The deficiency of mechanical pressure switch check
