One level switch technology for any medium

Sensor requirements are just as diverse as the media sensors are supposed to detect. Applications vary from dry running protection at pumps to reliable overflow or leak monitoring on to selective media detection with suppression of foam or separating layers.  Baumer is first to meet all these requirements with one single sensor technology. No matter whether it comes to bulk goods, powders, liquids, foam, or sticky or viscous media. One or more switching points will reliably monitor point levels of fluids in tanks, containers or pipes.








Frequency sweep technology:
An electrode integrated in the tip of the sensor together with the environment forms a capacitor. Depending on its dielectric constant (DC value), the medium determines the capacity value. This, together with a coil in the sensor electronics, creates a resonance circuit. Depending on the measured resonance frequency and the programmable trigger thresholds, the switching signal is triggered.

Replacement of vibrating fork point level switches

The widely used vibration level switches have vibrating forks that are quite large and which protrude quite a ways into the material being measured.

Since pasty materials are prone to stick to these forks, it can often cause measuring errors. Coarse granular media such as grains can easily become lodged between the forks and also cause measuring errors. Moreover, not only are the forks difficult to clean, but liquid and powder substances even require different fork designs.

With the sensors of the CleverLevel switch, no media remnants or solids are able to accumulate on the sensors. A precise and reliable level detection is thus ensured even under difficult circumstances.
