Level sensor for tricky cases

The diffuse reflection sensor FR900020 with focused radar signal has proven itself as a versatile problem solver for difficult applications since its market launch two years ago. The device, which can be used for ambient and media temperatures of up to 85°C, is parameterized via the standardized IO-Link interface, but can also be evaluated conventionally via the analog output and/or digital switching output, making it ideal for optimizing or retrofitting existing systems.

Application example 1:

The filling level of an aggressive liquid needs to be checked. As the radar signal easily penetrates straight plastic covers of several centimetres, it is possible to install and measure the fill level through container walls without coming into contact with the medium.

Application example 2:

The filling level of a liquid with heavy foaming is to be monitored. By screwing the sensor into a metal tube (1/2" process connection) via the entire detection range, the filling level of the liquid in a container can be detected despite the formation of foam on the surface.

Application example 3:

In a filling level application where containers or the medium is heated, optical sensors (fogging) or ultrasonic sensors (excessive measurement error) are ruled out.

With the radar sensor FR900020 radar sensor, however, reliable distance measurement at ambient temperatures of up to +85°C is possible without any problems.
