PR6426/010-140+CON021 power module

Description

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 films in bearings – 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
