InnoMeter® 4150-3

Measurement of vibrations on buildings

Application

The InnoMeter 4150-3 is designed for the measurement of vibrations on buildings acc. to DIN 4150-3 and SBR.

Vibrations from heavy building activities, traffic, machine operation or also detonations affect existing building stock. The InnoMeter 4150-3 measures these vibrations, evaluates acc. to the standard immediately and can inform about the occurred vibrations at any time.

For this purpose, a triaxial vibration sensor is assembled at the building. Its signals are transferred via InnoBeamer signal converters to the computer, where the InnoMeter 4150-3 is installed.

Properties

The InnoMeter 4150-3 combines vibration measurement, evaluation and display of results in one instrument. The most important characteristic: A report can be printed at any time since the evaluation takes place simultaneously with the measurement. Circuitous data transfer is not required here. You are ready for giving a statement immediately and at any time.

In the German standard DIN 4150-3 the main frequency is an important parameter as it determines the maximum allowable vibration level. The main frequency recognition is a problem for many instruments but not for InnoMeter 4150-3: It features permanently active, automatic frequency recognition and thus achieves exact results.

The measured data is available in differently detailed levels: You can see the overall status at once, but you are able to display more details concerning interesting events progressively. Detail depth reaches up to the recorded high-resolution vibration signal. This way, analysis with additional software can be carried out easily.

When it comes to printing a record, the detail depth can be selected as well. The most important data incl. the measurement curve fits on one A4 page. If required, the single events are printed as well. The period for the report to be printed can also be selected.

Automatic transmission of measurement results via email or notification of outsiders about alarms for instance via signal lamps is possible as well.
