General Description
Vibration Level Sensor VF is to detect presence of powder and granular material at a desired level to send signals utilized for alarm output or control of electromagnetic switches. The vibration plate at the tip of sensor is inserted in the tank to detect the presence of measuring object. Whit minimum inserted length and no mechanical moving parts, VF can achieve high durability.
Operational Description
The vibration plate has a magnet inside it, and when the pulse magnetic field produced by the electromagnet is applied, the magnet starts vibrating, causing the plate itself to vibrate. The vibration frequency changes when the plate is covered by medium or exposed, and causes the change in voltage at the electromagnet. The voltage change is detected and converted to electric signals to indicate the medium presence at the detection point.
