The HNS 3000 is an electronic level switch with integrated display. The float-based sensor for high precision analog monitoring of the fluid level has 1, 2 or 4 switching outputs and an analog output signal is available as an option.

In addition to the conventional minimum and maximum switching signal, with the 4 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 this HNS 3000 are primarily in hydraulics, e.g. for fluid level monitoring of a tank.

The sensor is available in probe lengths from 9.84 to 98.4 inches. The instrument is also available with or without temperature sensor.

Depending on the application, several different floats are available, e.g. stainless steel for aggressive media or plastic.
