Vibration Monitor (VM40)

Contains all components for comprehensive vibration monitoring, fulfilling all requirements under “The Planning Guidelines for Vibration Limits and Control in the Environment”, Department of Environment, Malaysia. Such vibrations can be evaluated with regards to possible damage to the structure or disturbance to the people and surrounding structures.

Properties

• Measures vibration to DIN 4150-3, BS 7385, SN640312a, Curculaire du 23/07/86 and freely adjustable custom non-standard measurements
• Integral triaxial piezoelectric shear type accelerometer with high sensitivity, electronics for signal conditioning, monitoring, recording and battery
• Large LED for vibration values, main frequency and graphical charts (ppv spectrum)
• Fail safe user guidance
• Continuous Peak Particle Velocity (PPV) logging and Time and event triggered for 100 000 events
• Relay outputs for external devices (Horn, Light etc)
• USB interface for data transfer
• Built-in rechargeable battery for long operation time (up to 15 days)
• Robust and waterproof aluminum case
• Option: Built-in Quadband GSM modem for SMS transmission of measurement at alarm events
• Option: Tripod floor plate with exchangeable feet
