Vacuum
Higher medium temperatures are possible provided the above limits for the switching device are
ensured by suitable measures (e.g. siphon). All pressure switches can operate under vacuum.
This will not damage the device.
Repetition accuracy < 1 % of the working range (for pressure ranges > 1 bar).
of switching points
Vibration resistance No significant deviations up to 4 g.
Mechanical durability With sinusoidal pressure application and room temperature, 10 x 106 switching cycles. The expected life
(pressure sensor)
depends to a very large extent on the type of pressure application, therefore this figure can serve only as
a rough estimate. With pulsating pressure or pressure impacts in hydraulic systems, pressure surge
reduction is recommended.
Electronical durability 100.000 switching cycles at nominal current 8 A, 250 VAC.
(microswitch)
A reduced contact load increases the number of possible switching cycles.
Isolation values
Overvoltage category III, contamination class 3, reference surge voltage 4000 V.
Conformity to DIN VDE 0110 is confirmed.
Oil and grease-free The parts of all pressure switches in contact with the medium are oil and grease-free
(except the HCD…and DPS…series). The sensors are hermetically sealed and contain no seals
(also see ZF1979, special packing).
