-1- WK 450 239 WK 450 239 up to 40 MPa 04.2001r. PRESSURE SWITCH TYPE HED 2 DESCRIPTION OF OPERATION Pressure switch type HED 2 is used to switch an electrical circuit on and off in relation to the given pressure value of an oil or another operating medium. Increasing pressure is supplied by a dumping tube via connector Stecko 4 sealed with the rubber ring 8. This pressure affects the bourdon tube 2 causing its deformation. As soon as the set pressure is reached, the bourdon tube actuates the micro switch 3 by means of the attached operating lever. Position of the micro switch and than time...

-1- WK 450 175 WK 450 175 up to 35 MPa 04.1999r. PRESSURE SWITCH TYPE USPH 1 Pressure switch type USPH 1 serves to switch an electrical circuit on and off by means of a micro switch under the influence of pressure variations in relation to the set pressure. The pressure switch may be used to control or monitor processes i.e. by means of a visual ( light ) or acoustic ( bell ) indicator. DESCRIPTION OF OPERATION At initial state the piston 2 is held in its lower position by the spring 4 and causes the lever 5 to press the micro switch end 6. Pressure affects the piston which pushes against...
