The accelerometer has a measuring range of 0 ... 200 m/s² for acceleration. In addition to acceleration, the vibration meter can also measure speed, displacement, frequency and an ISO 18016-3 measurement. During the vibration measurement, an FFT view is simultaneously displayed on the vibration meter. By pressing a button, it is possible to switch from the FFT analysis to the actual wave view of the vibration. This makes it possible to analyse and evaluate a vibration even better with the vibration meter. The magnetic holder of the vibration sensor of the vibration meter is designed in such a way that it can be attached to curvatures with a minimum radius of 20 mm / 0.78".
In addition to the vibration measurement, the accelerometer also has an external infrared temperature sensor. With this temperature sensor, surface temperatures between -70 ... 380 °C / 158 ... 716 °F can be measured. Another measuring function of the vibration meter is the contactless speed measurement. This means that the number of revolutions of ventilation systems, for example, can be checked with the vibration meter.
The accelerometer has a 4 GB memory. The measurement data can then be transferred from the vibration meter to a PC. Free software is available to analyse the data.
Because of its many functions, the accelerometer is a universally applicable measuring tool. Thus, the vibration meter can be used, for example, for maintenance work on generators or engines. Optionally, the vibration meter can be equipped with an ISO certificate.
