Measuring systems with eddy current transducers serve the measurement of mechanical quantities, such as shaft vibration and shaft displacement. Applications with such systems can be found in different industrial areas and laboratories.

Due to the contactless measuring principle, small dimensions, a rugged construction and the endurance against aggressive media, this type of sensor is optimally suitable for the use at all kind of turbo machines. epro offers a wide range of devices for measuring and monitoring.

Measuring quantities are e.g.:
Air-gaps between rotating and stationary parts
Vibrations of machine shafts and housing parts
Shaft-dynamic and eccentricity
Deformation and deflection of machine-parts
Axial and radial shaft displacement
Abrasion and position measurements at thrust bearings
Thickness of oil film in the bearing
Differential expansion
Housing expansion
Valve position

Construction and dimensions of measuring amplifier and relevant sensors apply to international standards, e.g. API 670, DIN 45670 and ISO 10817-1.

At connection via safety barriers, sensors and signal converters may also be operated in hazardous areas. The certificate of conformity according to the European standard EN 50014/50020 has been submitted.

To meet all requirements of measuring tasks and environmental conditions, epro offers eddy current sensors in several different versions and constructions.
The available sensor versions can be found in the order matrix.

The following standard versions are available ex stock:
PR 6423/000-000
PR 6423/010-000
PR 6423/100-000

Depending on the chosen version, the sensors have the following characteristics:
Housing with thread and axial cable outlet
Connections with self locking, waterproof plugs or open cable ends
Flexible cable protection
Adaptor plug at 1 m
