Contact Sensor Type Vibration Monitoring System

Features

■Mixed implementation with the conventional system “VM-9201” is possible
Mixed implementation with the conventional system “VM-9201” is possible
■A wide variety of pickups

Selectable from electrodynamic velocity pickup or piezoelectric accelerometer.

Electrodynamic velocity pickup

Specialized in medium frequency (up to 1,000 Hz) vibration detection. Correspond to velocity monitor.
