IVS-200 Industrial Vibrometer Sensor - Features

Introduction

Polytec’s IVS-200 Industrial Vibration Sensor is a ruggedized laser Doppler vibrometer for non-contact, on-line production vibration testing. An eye-safe visible laser is aimed and focused onto the part being measured.  IVS-200 is easily retrofitted into existing lines because the laser interferometer optics and electronics are all contained within a single, compact and robust industrial housing (IP 64).  The primary application of the IVS-200 is the monitoring of, with the goal of reducing, defects, noise and vibration in manufactured parts ranging from microelectronics to transmissions.  It enables faster, more accurate product quality monitoring and speeds up time-to-market.

    
The System

IVS-200 has a variable focus lens system for working distances ranging from about 70 mm to 2000 mm.  The focus can be locked for tamper–resistant permanent installations and there is a shutter for the laser.

IVS-200 will be factory configured with the velocity range best suited for the specific application.  If unwanted environmental low frequency vibrations are present, a high-pass filter can also be supplied.

The robust and tamper-proof industrial housing employs IP-64 protection. There are no operator controls on the housing that can be accidentally altered.  Despite the low laser power (sub 1 mW, eye safe), the high optical sensitivity of the IVS-200 enables measurements to be made from almost any surface without the need for special paints or tapes.

The IVS-200 vibration sensor has 2 connectors on its rear panel: The main connector supplies the power input (11 – 14.5 V DC), optical signal quality output and velocity signal output.  Velocity output is an analog voltage (± 4 V) proportional to the vibration velocity of the measurement object.   The second connector is intended for use with the optional IVS-310 optical signal-level display unit. The IVS-310 may be connected locally to the IVS-200, either for monitoring velocity signal quality or for service purposes.

The IVS-200 is supplied with a 5 meter long “open end” connection cable for integration into process control systems.  An optional IVS-320 rail mountable connection box is available with integrated AC/DC power supply, signal level bar-graph display and signal outputs.
