The ENS 3000 is an electronic level switch with integrated display. The instrument has 1, 2 or 4 switching outputs and an analog output signal is available as an option.

In addition to the standard minimum and maximum switching signals, with the 4 switching output version it is possible to set additional warning signals to prevent problems such as tank overflow or aeration of the pump. The ENS 3000 can be used for oil as well as water. The fluid type can be selected for specific applications via the menu.

Additional Information

N/A The main applications of the ENS 3000 are primarily in hydraulics, e.g. for fluid level monitoring of a tank.
The ENS 3000 is available in standard probe lengths of 9.80", 16.20", 20.50" and 28.70".
The instrument is also available with or without an integrated temperature sensor.

Special Features

N/A

  • 1, 2 or 4 independent PNP transistor switching outputs
  • Selectable for use with oil or water
  • User-selectable switch outputs based on the measured value
  • Switching and switch-back points can be adjusted independently
  • Selectable analog output (optional)
  • Simple to operate due to menu-based key operation

Setting Options

N/A All settings available on the ENS 3000 are combined in 2 easy-to-navigate menus.
To prevent unauthorized adjustment of the instrument, a programming lock can be set.

Additional Functions

N/A

  • Switching mode of the switching outputs adjustable (switching point function or window function)
  • Switching direction of the switching outputs adjustable (N/C or N/O function)
