Handheld Tachometer
Linear Velocity Transducer - LVT
The LVT is based on the principle of magnetic induction and provide reliable velocity measurement in a linear motion. Passing a magnet through the coil form generates a voltage proportional to the magnets velocity and field strength. This output signal is used to carefully monitor component velocities in various applications.
Tachometer
The tachometer measures the angular velocity of a rotating shaft using one of two methods. The first type connects a DC generator (motor) to the shaft which produces a voltage proportional to the increase in shaft angular velocity. The second type utilizes a magnet with a pickup coil. As the magnet passes the coil a pulse is generated. The pulse magnitude and frequency are proportional to the angular speed.
