EDS 3000 Series
The EDS 3000 electronic pressure switch is the result of joint development and innovation in the field of adjustable pressure switches with display. It is a compact unit which combines a pressure switch, digital display, and transducer for controlling pressure in hydraulic and pneumatic applications. The most noticeable innovation is the alignment of the serial four-digit display. After mounting, the switch may be turned as a whole. Additionally, the front panel with push buttons may be turned. This eliminates the need for mechanical adapters. Display units can be shown in bar, psi, or mpa. It is also possible to free scale the pressure range to any desired engineering unit, such as force or tonage. Pressure ranges from vacuum to 9000 psi are available. Switching outputs in one or two switch versions with or without analog output are available when choosing model code.

EDS 300 Series
The EDS 300 is a compact unit which combines a pressure transducer, digital display, two switches, and analog output for controlling pressure in hydraulic and pneumatic systems. The transducer converts system pressure into an electrical signal for the display and analog output. External adjustments allow the user to set the pressure switch points and switchback points. The 3-way functionality of this device offers a large cost savings to purchasing a gauge, transducer, and switch in

EDS 1700 Series
The EDS 1700, with its built-in pressure measuring cell, a 4-digit display and the 4 switching outputs, offers the user all the advantages of a modern electronic pressure switch.
Four switching points and switch-back points can be adjusted very simply and independently of each other via a membrane keypad. For optimum incorporation into monitoring systems (eg with PLC) an analog output is also available (4 to 20 mA or 0 to 10 V).
The main applications of the EDS 1700 are in hydraulics and pneumatics. The instrument is ideal for use where frequent switching cycles (several million) require permanent switching point accuracy or simple and precise adjustment.
