Hydac Electronic Pressure Switch EDS 410

Hydac Electronic Pressure Switch EDS 410

The electronic pressure switch EDS 410 has been specially developed for use in volume production machines, and is based on the EDS 4000 pressure switch series.

The EDS 410 is available with 1 or 2 transistor switching outputs (PNP), which can be defined as either N/C or N/O.

The switching and switch-back points of the EDS 410 are factory-set according to customer specification.  As with the EDS 4000 standard model, the EDS 410 has a ceramic measurement cell with thick-film strain gauge for measuring relative pressure in the low pressure range, and a stainless steel measurement cell with thin-film strain gauge for measuring in the high pressure range.

Various pressure ranges between  0 .. 1 bar and 0 .. 600 bar as well as different electrical and mechanical connection types are available.

Special features:

• 1 or 2 transistor switching outputs (PNP), either as N/C or N/O
• Factory-set according to customer specificationl
• Accuracy ≤ ± 1 % FS
• Highly robust sensor cell
• Very small temperature error
• Excellent EMC characteristics
• Excellent durability

Hydac Electronic Pressure switch EDS 1700

Hydac Electronic Pressure switch EDS 1700

The EDS 1700, with its integrated pressure measuring cell, 4-digit display and 4 switching outputs, offers the user all the advantages of a modern electronic pressure switch.
4 switching points and switch-back points can be adjusted very simply and independently of each other using the keypad.
For optimum incorporation into monitoring systems (e.g. with PLC), an analogue output (4 .. 20 mA or 0 .. 10 V) is also available.
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.

Special Features:

• Integrated pressure sensor with strain gauge on stainless steel membrane
• Accuracy 0.5 % or 1 % FS
• 4-digit display
• Simple operation via key programming
• 4 limit relays, switching points and switch back points can be adjusted  independently
• Analogue output signal selectable
• Many useful additional functions
• Optional mounting position (pressure connection on the top/ bottom, keypad and display can be  turned through 180°)
• Can be set to display values in any unit of measurement e.g.: kN, kg, psi, ...
