The HNS 3000 is an electronic level switch with integrated display. The float-based sensor for high-precision analogue monitoring of the fluid level has 1, 2 or 4 switching outputs and an analogue 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 main applications of the HNs 3000 are primarily in hydraulics, e.g. for fluid level monitoring of a tank.
