Sunny Instrument LVS-01 is an out-plane vibrometer which uses Laser Doppler Principle to measure object vibration along the laser direction.It uses non-contact measurement method, and has auto-focus/long-distance focus and focus points storage functions. Preferred work distance is from 0.35m to 20m. The equipment is insensitive to disturbance, and has very high resolution and very wide dynamic measurement range. It is the basis of any other kinds of vibrometers. It is also the non-contact measurement equipment with high mature technology from Sunny Instrument Singapore and already widely used in many universities, institutes and large factories.

Features

  • Non-contact measurement:Solve the problem that contact measurement method is affected by environment conditions (e.g. High Temperature, Strong Magnetic etc.) in reality applications
  • Upgrades available:External Scan Unit is available, and auto-scan function is achievable with it, so it could be upgraded to Scan Laser Doppler Vibrometer.
  • Multi-function:Configurable Optical Unit achieve auto-focus, long-distance focus and focus points storage functions.
  • Dual Mode:Be able to output analog/digital signals.
  • Complete solution:include optic circuit, signal processing, software analysis and data acquisition functions.
  • Personalization (Be able to install intelligent software with real-time estimation of measurement result, real-time display change trends and so on, according to specific requirements from customers.)
  • Portability(can be fixed on tripod, easy to carry)
