| Application | ||
|---|---|---|
| Function principle | Limit detection maximum or minimum detection in tanks or pipelines containing liquids of any kind, even in hazardous areas |
|
| Function and system design | ||
| Measuring principle | The forks of the sensors vibrate at their intrinsic frequency. This frequency is reduced when covered with liquid. The change in frequency then activates the limit switch. |
