詳情介紹
MODEL: VC12N, VC12F
Main application
Solid detection of small to medium size hoppers or pipe inside
Main feature
-
Compact with 175mm detector and robust
-
Ideal for small to medium size hoppers or pipe inside
-
Stable operation based on coil impedance detection.
-
Resists temperatures up to 150℃ as standard
-
Universal power supply (100 to 240V AC)
Principle of operation
Measurement is based on coil impedance detection. A magnet and an electromagnet inside the detector vibrate the plate. Current that flows on the electromagnet decreases when the detector is covered by the measured solid. The sensor detects this change to determine solid presence and gives an output.
When the detector is not covered by the materia
-
The electromagnet vibrates at its operating frequency when alternating current is applied.
-
Back electromotive force on the electromagnet becomes the largest due to change in magnetic field from the magnet
-
The sensor determines the detector is not covered by the material.
When the detector is covered by the material
-
Applying alternating current does not cause the electromagnet to vibrate at its operating frequency.
-
No back electromotive force occurs because the magnet is stationary.
-
The sensor determines the detector is covered by the material.
