It is used to control vibration state of the equipment and units operating in different industries (gas, oil, power generation, metallurgy, chemical industries etc.).

It consists of:

Three-axis vibration transducer DVA-I3. Normalizing transducer. Connecting harness.

Distinctive features

Multiplex data exchange channel (fieldbus);
Reading of instantaneous amplitude of signals with sampling frequency;
Availability of analogue (4 ± 20 mA) and discrete (relay) outputs;
Measuring with respect to three coordinates;
Explosion proofness – 1Ex[ib]dIIBT6.
