Optimised for use in hydraulic oils and coolants No maintenance necessary, free from mechanical parts
Easy adjustment and setting of the output function via inductive teach button

Improved performance thanks to IO-Link

2 configurable switching outputs defined by media or temperature
Adjustment to different media (e.g. water/oil)

Capacitive point level switch LI
The LI513 measures media such as oil and water without using any moving parts. Reliable and maintenance-free. Build-up which causes mechanical sensors to stick has no detrimental effect. The same applies to water temperatures of up to 85°C. Talking about temperature: Thanks to the second switching output this measurement value can easily be used for process control in addition to level measurement. Alternatively, it is possible to monitor the level of two different media. If you want to, you can drop the LI into cold (or hot) water. The factory setting makes it possible. Everything else the sensor is taught instantly using the inductive teach button or IO-Link parameter-setting.

As you can see the LI513 has a head start over any float. Even though – or rather because, it has no moving parts. Capacitive and maintenance-free level measurement.
