Compact and low cost. Ideal for integration into solid equipment.
Principle of Operation
The detector incorporates a piezoelectric crystal and an acceleration pickup.The system detects and amplifies the small phase shift of the pickup. It then applies the amplified signal to the piezoelectric crystal, causing the crystal to strain and make the detector vibrate. When the measured material covers the detector, vibration decreases or stops depending on the weight or pressure the material applies. The sensor detects the change in vibration, and gives an output to indicate level detection.
