General Description
The vibration sensor, Model VC12 is used for level detection of solids, fine powder, granular, pellets and sediments under the liquids such as sludge and sand. The output signal from the sensor is used for the alarm and/or control of electromagnetic switch. When the detection pipe is covered.
Operational Description
The vibration rod of new VC series is constructed by using the electro magnet and the permanent magnet. When the electro magnet is energized, the electro magnet and permanent magnet are attracted and repulsed. This movement makes vibration
The construction of vibration probe is similar to the motor. When the motor is energized by the battery, the back electromotive current is generated by the influence of permanent magnet and coil. When the vibration rod is covered with solids or powdered material, the current flowing to the lead wire is increased by damping of the back electromotive current. The amplifier detects this shifting of current laval, and converts to output signal.
