Capacitive level switch for industrial applications

The CLS-1000 capacitive level switch uses a smart measuring principle to reliably detect levels. Inside the sensor there is an electrode which, together with the container or an additional opposing electrode, generates an electrical field. Normally, the capacitance of this electrical field is relatively low – so long as only air or another non-conductive medium is present.

However, as soon as a medium such as a liquid comes close to the sensor or touches it, the dielectric constant between the electrodes changes. This change leads to an increase in capacitance, which the CLS-1000 detects and evaluates. In this way, the sensor can precisely determine whether a certain level has been reached.

Thanks to the non-contact measuring principle, the CLS-1000 is particularly wear-resistant, with no mechanical parts needing to be moved. This makes it ideal for applications where a long service life and minimal maintenance are required. If required, the CLS-1000 can also be equipped with two switch points to detect different filling levels.

Another highlight of the sensor is that, on request, a temperature sensor can also be integrated. With this, in addition to the level, the temperature of the medium can also be monitored, which, in many industrial applications, enables additional process control.

This robust yet cost-effective design makes the CLS-1000 an ideal solution for level monitoring in a wide range of applications.
