The EDS 300 is a compact electronic pressure switch with integrated digital display. 4 different output versions are available: with one switching point, with two switching points and the same two variants, also with an additional analogue output signal 4 ... 20 mA. The switching points and the associated hystereses can be set per keyboard. For optimum adjustment to the respective application, the device offers a multitude of additional setting parameters, e.g. switching delay times, opener/closer functions for the outlets. The main applications of the EDS 300 are pressure and limit value messages in the areas of hydraulics and pneumatics or wherever a high switching frequency or a constant switching accuracy is more than mechanical pressure switches can provide. The device is ideally suitable for setting up accumulator charging functions or pumps and compressor control units as well as for the monitoring of pressure or limit values on ship transmissions, diesel motors, pumps and general hydraulic and pneumatic plants.

• Integrated pressure sensor with thin-film DMS on stainless steel diaphragm
• Compact, robust design
• Accuracy ±1% FS
• 3-character digital display
• Simple handling through key programming
• Switching points and reset hysteresis can be adjusted independently of one another
• Window function
• Many helpful additional functions
• Also available with Schiff's approval
