The 901 Prescal is an adjustable pressure switch meaning that the switching pressure is fully adjustable via the knob on the top of the pressure switch.  The diaphragms are of an elastomer material and again can be selected for the application.  Options of a NBR, FKM and EPDM diaphragm material are possible and for more aggresive and corrosive media a Chemraz diaphragm is used.  The pressure switch can be used on air pressure and oil pressure and any non viscous liquid.  The pressure switch when activated with eith be NO or NC and switch the supply voltage that is connected which can then be taken off to a PLC, Control panel, alarm or sounder of some description.
