  • General information
    reduced when a lower switching point is selected Adjustable switching differential can also be obtained on certain pressure switch models Direct acting connector system The electric contacts are directly mounted or directly influenced by the diaphragm or the piston In other words switches do not have a micro switch but have to be ordered in normally open or normally closed versions Load The electrical data that is indicated for alternating voltage unless otherwise prescribed At currents below 20 mA gold plated connectors should be used Max current is then mA Gold plated connectors can be supplied for all pressure switches with a micro switch Diaphragm pressure switch The media presses on a diaphragm that in its turn influences a micro switch via a mechanism Piston pressure switch The media presses on a piston that in its turn influences a micro switch via a mechanism Piston pressure switches should not be used for air or gaseous media Electronic pressure switch Electronic pressure switches are based on the same principle as a pressure transducer see the pressure transducer section Instead of an analogue signal as an alternative the electronic pressure switch has two set points These set points can be set using a PC and a special program or directly on the pressure switch The electronic switch is used to advantage when there are major demands for accuracy or service life The switching point is a PNP connector Temperature range The temperature range in which the switch can operate according to the given specification accuracy etc Pressure setting When setting the switching point consideration should be given to the fact that the spring settles after a number of switches and the set value can change The switch should therefore be checked after some 20 switchings or 24 hours On the customer s

  • What is a pressure switch?
    again by an amount greater than the hysteresis the switch opens again For a normally closed switch the action of the contacts is reversed By turning the set screw the pressure switch can be adjusted within its pressure switching range By using a micro switch with changeover function the normally open and normally closed operation can be combined into a single pressure switch The plunger operates a swivel contact In the un pressurised state the circuit is closed by the normally closed contact If the pressure applied exceeds the adjusted set point then the swivel contact changes an closes the circuit using the normally open contact Hysteresis Hysteresis dead band or differential is the term given to the difference between the switching points when the pressure is rising and when it is falling For pressure switches with non adjustable hysteresis it is a function of the swtich design For SUCO switches with adjustable hysteresis it can typically be set in the range of 10 to 30 of the switching point The hysteresis is dependent on the switching point Switching frequency The switching frequency provides information about the possible number of switching cycles per minute The figure given of 200 minute is intended only as a guideline Depending on the type of switch and the operating conditions a considerably higher number of cycles can be achieved Set point tolerances The switching point tolerances we quote refer to room temperature RT operation and a pressure switch in new condition The effect of temperature and aging can change the switching points additionally Membrane materials NBR Buna N The most widely used standard material A special SUCO material mixture which shows good low temperature flexibility so that even at low temperatures the sealing of the pressure switch is maintained EPDM Ideal for those applications
