技术参数节选 LVL-A5-G1S-E5V1-CG-EMS
| 产品阐述 |
|---|
| Vibration Limit Switch |
| Application | ||
|---|---|---|
| Function principle | The tuning fork is brought to its resonance frequency by means of a piezoelectric drive. If the tuning fork is covered by liquid, this frequency changes. The electronics monitor the resonance frequency and indicate whether the tuning fork is freely vibrating or is covered by liquid. | |
| Input characteristics | ||
