Pressure switch for the hydraulic measuring technique

The new pressure switch Multi-EPC is a 3 in 1 instrument:

Pressure measuring instrument with display, controller and limit value monitoring.
This instrument has a four-digit display. Programming adjustments are carried out via a foil keyboard with three keys. Two light emitting diodes show the current state of one respectively two switching outputs.

All adjustments are selectable in a clearly laid out operting menu and contain the adjustments of the switch-on and switch-off pressures, switching delays and the analogue output. In addition to this, variable hysteresis- and window functions can be programmed. The supply voltage is externally supplied and can vary between 15 to 30 VDC.

Electronics and the pressure measuring cell are embedded in a solid zinc – die-casting housing, which allows a 280°- turn around (rotation) about the the longitudinal axis.

The following measuring ranges are available: 0 to 25, 100, 250 and 400 bar. The instrument is available in a standard- or in a DESINA®-conformable execution.
The pressure switch serves for the monitoring of pressure in fluid-technical, hydraulic and gaseous pressure systems.

Due to this, the EPC allows the detecting of pressure changes, which are recorded as switching conditions via pre-adjustable limit values, and evaluated for external controllings. At the same time, the user can record pressure curves via the analogue output.
