Contact Sensor Type Vibration Monitoring System (VM-9301 Series)

Permanent vibration monitoring for systems such as motor, pump and blower.
Monitoring system suitable for multi-channel measurement.
Frequency range, measurement range or output signal can be customized.

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.
