Key values
EWA Sensors develops condition monitoring sensors for machines with integrated Early Warning Analytics.
The sensors are autonomous real-time sensors with a fieldbus interface.
We provide assessed knowledge of the machine’s health and condition and issue warnings/alarms when action is required.
Condition monitoring
Machine condition monitoring is a range of techniques and technologies used to monitor the condition and performance of various machine components within a machine. The quality of condition monitoring parameters depends on two things: sensor signals and algorithm design.
Sensor parameters
- Slip and rotational speed (RPM)
- Rotational direction
- Magnetic RPM
- Magnetic field strength
- Duty cycle
- Number of starts/stops and operating time
- Vibration and Imbalance
- Surface temperature
- Cavitation detection
- Detection of bearing faults
- Bearing and gear wear
- Machine condition
EWA platform
The EWA sensor monitors the machine’s essential parameters, and its robustness comes from using a multi-sensor approach that combines two fundamental signal domains: vibration and the magnetic field.
The EWA sensor calculates a wide range of parameters with status updates every second. via modbus:
What do we do differently?
Fault detection
The EWA sensor is much more than vibration detection, as it indicates the specific developing fault type for targeted service measures.
Robust measurements
EWA is a hybrid sensor platform that combines 3D vibration analysis with the rotating magnetic field in 3D. The analysis provides insight and is robust enough to meet the demands of industrial applications.
Early Warning Analytics
The sensor has an Early Warning Analytics (EWA) layer on top. This supports daily operation by issuing a warning if a fault begins to develop, and an alarm if the severity of the fault reaches a stage where rapid service action is recommended.
Waterproof
The sensor is designed for both dry-installed and submerged machinery, rated to a depth of 10 metres.
Generic sensor
Easy and quick installation. The sensor calculates all necessary information itself, and no additional information about bearing type, etc. needs to be added.
