HYDAC EDS1700 series pressure relay, pressure switch, 4 relay switching contacts, 1 analog output and 4 digital displays. Switching point, return switching hysteresis and auxiliary functions can be set with touch keys. The pressure switch is a component in the hydraulic system that causes the electrical contact to operate when the fluid pressure reaches a predetermined value. The pressure relay can also be defined as a hydraulic component that converts pressure into an electrical signal. The customer can output an electrical signal at a certain set pressure by customizing the pressure relay to suit their own pressure design needs.

Germany HYDAC pressure relay EDS1791-P - 250-000 working principle:

Pressure relay has four structural forms: plunger type, diaphragm type, spring tube type and bellows type. The following is an introduction to the working principle of the plunger pressure relay:

When the pressure of the fluid entering through oil inlet 3 at the bottom of the relay reaches the set pressure value, the plunger 2 will be pushed up and the displacement Press the microswitch 4 to operate after being reinforced by the lever. The action pressure of the relay can be adjusted by changing the amount of compression of spring 1.

Applications: for safety protection, to control the sequential operation of actuators, for openingand closing pumps and for unloading pumps.

Note: The pressure switch must be placed where the pressure changes significantly in order to provide an electrical signal. If the pressure relay is placed on the oil return pipe, since the oil return pipe is directly connected to the oil tank, the pressure will not change, so the pressure relay will not work.
