About EDS 300 Pressure Switches:
The EDS 300 is a compact, electronic pressure switch with digital display. The pressure measurement is based on a thin film strain gauge sensor cell in stainless steel. All parts in contact with the fluid are in stainless steel, and are welded together. Since no seals are required in the sensor chamber, leakage is eliminated. Two relay switching outputs with N/O function and an additional analog output signal (4 to 20 mA) enable the pressure switch to be incorporated into the most modern control concepts. The switching points and the corresponding hysteresis can easily be adjusted via the keypad. For optimum adaptation to a particular application, the unit has many additional adjustment parameters, e.g. switching direction of the relays, switching delay times. Areas of application are pressure or maximum value monitoring on marine transmissions, diesel engines, pumps and general hydraulic and pneumatic systems.
