Wide-ranging applications such as rotating machinery: IMV manufactured electromechanical speed pickup.
VP-3133 series / VP-3134AEX / VP-3144 series / VP-3213 series / VP-3354A / VP-3364A, etc.
Due to its high sensitivity and wide linear range, it is suitable for diagnosing the deterioration of rotating machinery.
A dynamic electric pickup is a sensor that measures the voltage generated when a coil moves back and forth between magnets due to the vibrations of a machine. The linear pendulum type supports a coil shared with an inertial weight using a diaphragm spring or coil spring, allowing it to perform linear reciprocating motion between magnets to generate voltage output. It is suitable for detecting the deterioration of rotating machinery due to its high sensitivity and wide linear range. However, there are structural limitations on the installation direction and angle. 【Features】 - High detection sensitivity, stable operation, and wide linear range - Relatively large output - Low internal resistance allows for the use of long cables - No external power supply required (self-generating type) - Ideal for vibration measurement of sleeve bearings

Applications/Examples of results
The linear pendulum type supports a coil shared with an inertial weight using a diaphragm spring or coil spring, allowing it to perform linear reciprocating motion between magnets to generate voltage output. It is highly sensitive and has a wide linear range, making it suitable for detecting deterioration in rotating machinery equipment. Due to its structure, there are limitations on the installation direction and angle.

- Installation Method The pickup with a natural frequency of 14 Hz can be installed using both methods (a) and (b), but the pickup with a natural frequency of 4.5 Hz is limited to (a) or (b). In either case, it cannot be installed with the arrow pointing downward as shown in (c). A special fixture is required to ensure the arrow points upward.
