Three-dimensional measurements within 0Hz to 1,5 kHz frequency range can be made with a built-in MEMS sensor. In combination with 3D high sensitive silicon gyroscope it allows for determination of mVIBE movement in 6D space.
Measurement capabilities are complemented by an ultrasound microphone, which registers sound in range up to 51 kHz. It’s a tremendous tool to detect shocks, which occur in damaged bearings and gearboxes. Together with the dedicated software they allow to detect leakage in compressed-air systems.

Piezoelectric accelerometers are a main source of signal, which measure vibrations in two directions. Their outstanding parameters combined with 24-bit signal conversion allow to achieve accurate measurement results without necessity to change measurement ranges. Wide frequency band (0,5 Hz to 20 kHz) satisfies requirements of the most applications connected with technical condition assessment or damage diagnostics of machines and building constructions.
The WiFi is used to transmit the measurement information from mVIBE sensor to a smartphone or a tablet. In permanent monitoring systems it can be sent directly to local or external diagnostic cloud via a local network. The mobile phone or tablet with mVIBE application serve as user interface. This provide flexibility and easy of use of mVIBE multi sensor unit.
In the basic version mVIBE operates with mVIBE App available in GooglePlay. It creates fundamental tool for machines technical state evaluation and fault diagnosis. The advanced options covering signal storage in database, localisation structure with NFC identification, fully configurable detailed signal analysis functions are offered by mVIDIA/mVIDIA cloud software.

mVIBE is powered by internal Li-Ion rechargeable battery. Its high capacity ensures operating time up to 8 hours (continuous measurement with data transmission). The sensor can be attached to the investigated object by magnetic holder or M6 screw thread. Optional magnetic holder for curved surfaces is available.
