PVE - Variable Moment (VM) technology

When using a high-frequency vibratory hammer with variable moment (VM) with a adjustable moment of 0 to max 2300 rev. per minute, critical vibrations in start-up and stop are eliminated. After passing the critical frequency area, the eccenter weights are automatically adjusted and synchronised to the current eccentric moment.

Guide for Vibration Machine amplitude, frequency, G-Force ...

If frequency is how fast a machine vibrates per second, then amplitude is how strong the vibration is or how high the platform moves from its resting place. Some manufacturers boast a really wide frequency range but hide the fact that their machines have a low amplitude. In order for a machine to be effective, it must have a sufficient ...

High Frequency Amplitude Detector for GMI Magnetic Sensors

A new concept of a high-frequency amplitude detector and demodulator for Giant-Magneto-Impedance (GMI) sensors is presented. This concept combines a half wave rectifier, with outstanding capabilities and high speed, and a feedback approach that ensures the amplitude detection with easily adjustable gain.
