Laser-Based Tool Measures Vibration

July 17, 2014
SKF introduced the SKF Laser Vibrometer, a laser-based tool for measuring vibration from fans, electric motors and pumps.

The SKF Laser Vibrometer (MSL-7000 series) is a laser-based tool designed to measure vibration and structure-borne noise from fans, electric motors and pumps without making contact with their surfaces.  The non-contact vibration sensor offers a compact solution on every measurement surface, regardless of environmental conditions.  The technology benefits from a high-end contactless velocity proportional sensor and is suitable to perform process-integrated, “end of line” acoustic inspections of “noise critical” equipment for information on manufacturing quality and compliance with a product’s acoustic emission limits.

The direct integration of the SKF Laser Vibrometer into a production line can create a real-time quality control system for products enabling pass/fail decisions on the basis of structure-borne vibration.  The vibrometer supports flexible resetting of manufacturing batches and test set-ups.

This digital, single-unit laser tool does not require servo-mechanisms or noise protection gear during use.  The vibrometer can cover acoustic measurements from 0.2 Hz (for slow rotations) up to 22 kHz and can integrate easily into a manufacturing line and existing control systems.  The vibrometer can be used in the field with SKF Microlog portable vibration monitoring and data collection instruments, allowing users to perform advanced measurements and monitoring in areas otherwise difficult to reach, on hot or rotating parts, and through glass.

A special package (MSL-7000C) developed for laptop use with SKF FPM Software and a mobile data acquisition card also is available.
