Portable Four-Channel System for Measurement and Analysis in Sound and Vibration Sound Level Meter to IEC 61672 Real-time frequency analysis Modal analysis Analysis of operating vibration Resilent balancing Tracking analysis Quality inspection and testing Pass-by noise to ISO 362 Building acoustics Messtechnik GmbH

This powerful and versatile system features small dimen- • sions and minimum power consumption. Its integrated sensor interface allows commonly used sensors to be connected. It is prepared for the Smart-Sensor interface standard. • Apart from four input and output channels for highly dynamic signals, Harmonie has additional inputs for rotational speed and slowly-fluctuating operating data. This makes Harmonie especially suitable for measure- * ments in vehicles and on test stands. Harmonie was developed for use in the following fields: ■ Car manufacturer and their subcontractors • - Design...
