The VM 40A Vibration Analyser was designed for vibration and shock metering on buildings, bridges, towers, and other artificial structures. The Vibration Analyser measures vibrations in accordance to DIN 4150-3, BS 7385 and SN 640312A standards. With its internal memory for up to 100,000 readings, the VM 40A Vibration Analyser can determine the effects of construction sites, traffic, or industrial processing on buildings over a long period of time. You can choose between time-based and event-based recording, as well as between recording of short-time and long-time vibrations. It is also possible to set threshold levels which trigger an alarm signal when exceeded.
The Vibration Analyser is very easy to use and can be configured for different applications in no time. The measured data can easily be viewed on the integrated display of the device. Here you can see the vibration speed in all 3 directions. The Vibration Analyser has an integrated NiMH battery which makes it suited for mobile use on-site. A mains adaptor for stationary use is also included in delivery.
