The EWA sensor has the computer resources close to where data originates – at the ”edge”.

Data processing and evaluation carried out locally in the sensor means both faster and real-time data and ensures more robust and reliable results.

As data remains in the private network, this increases data security.


The EWA sensor states high quality pre-processing data for integration, presentation and eventual further data analyses in an AI, Cloud or CTS system.

Increased Uptime & Efficiency

Increase system uptime

An unplanned production stop has large costs, in lost production and in customer loyalty. It is of big importance to reduce unplanned system downtime.

Extend asset lifetime

Machine monitoring secure that it is safe, reliable and efficient over the machine operating life. Wear and damage on machine parts is identified before machine breakdown, extending the machine lifetime

Optimize service, maintenance planning and costs

Monitoring and supervision of wear and damages on machine parts make it possible to optimize service planning and reducing maintenance expenditures.

Condition monitoring

Condition monitoring is monitoring of a set of conditions in machines. It is used to recognize significant change to indicate the fault. When monitoring is done continuously and in real-time, it is possible to have actual status of a condition, and also following the fault development over time.



The uneven distribution of mass around a rotating axis, during rotation. This unequal mass will create a centrifugal force, resulting in force on the bearings, especially at higher speeds.

Reverse rotation

A machine can run in forward or reverse rotation. This can be due to a forced control or an unintended situation.


Electrical RPM

The desired rotation speed in RPM applied to the stationary part of the motor, the stator (the driver).

Rotor RPM

The actual mechanical rotation speed of the rotating part of the motor (the driven part).

Slip Speed

The difference between synchronous and asynchronous speed. Slip increases with increasing load, as it provides a greater torque on the shaft.


Duty cycle

Explain the share of machine operation time and machine stopped, for the last 24 hours.

Number of start/stops

Number of start/stops States how often the machines is started and stopped, for the last 24 hours.

Operation time

States the total machine operation time, for the last 24 hours.


Cavitation is the rapid creation and subsequent collapse of air bubbles in a fluid.


Monitoring of the skin temperature. Change in temperature can be an indication of motor fault or pump blockage.


Monitoring of the actual vibration level.

Vibration Level RMS

An energy level for the vibration, calculated from the spectrum in the frequency range from 10 to 1,000 Hz.

False Brinelling

False brinelling occurs when there is background vibration while the motor is not running.

What we do differently

Fault detection

The EWA sensor is much more than abnormally detection, as it states the specific developed fault type, for targeted service measures.

Robust measurements

EWA is a hybrid sensor platform, combining the rotating centrifugal force in 3D and the rotating magnetic field in 3D with edge analytics, which benefit in robustness and contribution immunity from other operating machinery.

Early Warning Analytics

Sensor parameter have an added Early Warning Analytics (EWA) layer on the top. This support daily operation by stating a warning, is case a fault starts developing, and an alarm if the fault severity is at a state where fast service action is recommended.


The sensor is for both dry-installed and submerged machinery, rated to a depth of 10m.

Generic sensor

Easy and fast installation. The sensor calculates all needed information itself, and no additional information about bearing type etc. must be added.
