Dirt detection system for greenhouse glass measures mechanical resonance |
| 摘要 |
<p>A dirt detection system has a piezo electric actuator (2) fixed to a glass (1) to excite a resonance at nodes with measurement by a piezoelectric sensor (3) for frequency analysis (6) and temperature measured by platinum resistance (4). Includes an INDEPENDENT CLAIM for a cleaning element actuated by the sensor.</p> |
