What are the industrial applications of pressure switches?
Water applications Standard piston switches are not suitable for water applications. Pressure switches in stainless steel with EPDM seal have a special sealing system and can therefore also be used for water with corrosion protection, water mixtures or emulsions. The use of other fluid mixtures should be clarified with SUCO ESI North America (e.g. swelling […]
What is Pressure Hysteresis?
Rising / falling switching point The pressure difference between the rising (upper) and falling (lower) switching points (refer to the figure, e.g. NO) is known as hysteresis (switch-back difference). Hysteresis has no constant value due to the structural layout of a mechanical pressure switch. In absolute values, the hysteresis is also the smallest with the […]
What is the classification of switches in power electronics?
It has proven useful in many applications to deploy our pressure switches with silver contact rivets ensuring that they are fail safe to 10 mA and 10 V. Variants with gold contacts are available in our catalogue for even lower currents and voltages. Potential-free – galvanically isolated Mechanical pressure switches from SUCO ESI are […]
