Electronic Level Switch ENS 3000 - HYDAC

1 E SwitchENS 3000 Description:The ENS 3000 is an Electronic Level Switch with integral display. The unit has either 1, 2 or 4 switching outputs and an analogue output signal is available as an addition to the standard minimum and maximum switching signals, it is possible with the 4 output version to set additional warning signals to prevent SUREOHPV VXFK DV WDQN RYHU RZ RU aeration of the ENS 3000 can be used for oil DV ZHOO DV ZDWHU 7KH XLG W\SH FDQ EH VHOHFWHG YLD WKH PHQX IRU VSHFL F main applications of the ENS 3000 DUH SULPDULO\ LQ K\GUDXOLFV H J IRU XLG Level monitoring of a ENS 3000 is available in standard probe lengths of 250 mm, 410 mm, 520 mm and 730 unit is also available with or without an integrated temperature features.
