Three-dimensional absolute vibration sensor DVA-I3 ITsFR.402248.005

Not available


Measuring of root-mean-square values (RMS) of vibration velocity with respect to three coordinates/or their module of vector sum.

Area of Application

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.
