Click2Contact

The Hydac HNS 3000 is an electronic level switch with an integrated display. The float-based sensor for high-precision analog monitoring of fluid level has one, two or four PNP switching outputs, with an analog output signal available as an option.

Switch outputs are user-selectable based on measured value, with independent adjustment of the switch and switchback points.

In addition to a conventional minimum and maximum switch signal, it is possible to set additional warning signals to prevent tank overflow or pump aeration with the 4-output version.

The sensor is available in probe lengths from 250 to 2500 mm. The instrument is also available with or without temperature sensor.

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