Introduction of Kunshan tachometer manufacturers classification of tachometers

Centrifugal tachometer

Centrifugal tachometer is composed of transmission part, receiver and indicator. It is a traditional speed measuring tool, its main advantages are simple structure, convenient use, and the disadvantage is that the accuracy is relatively low. The working principle of the tachometer is the principle of centrifugal force and rotation angle or proportion of rotating mass. When the shaft of the tachometer is rotating, the weight hammer on the centrifugal device leaves the axis under the action of inertia centrifugal force, and drives the needle to rotate through the transmission device. The rotation speed of the shaft is determined according to the position of the pointer in the balance of inertia centrifugal force and spring force.

The magnetic tachometer uses the rotating magnetic field to produce the rotating force on the metal cap, and indicates the rotation speed by balancing the rotating force and the wire force. Magnetic tachometer is a model of successful use of magnetic force, and a mechanical tachometer which uses magnetic principle; Generally, it is installed locally, and it can be installed in short distance with soft shaft. Magnetic tachometer, because of its simple structure. When installing in different places, the flexible shaft is easy to be damaged.
