EPRO CON021 Sensor Signal Converter

Description

The signal converters CON 011, CON 021, CON 031 and CON 041 in connection with eddy current sensors of type PR 6422/.. to PR 6426/ serve the measurement of static and dynamic displacements. Applications with such systems can be found in different industrial areas and laboratories. Due to the contactless measuring principle, the rugged construction and the resistance against aggressive media, the sensors can be operated with these converters which are optimally suitable for the use at all kinds of turbo machinery. Epro offers a wide range of products for measuring and monitoring. Measuring quantities are e.g.:

• Air-gaps between rotating and static parts

• Vibrations of machine shafts and housing parts

• Shaft-dynamic and eccentricity

• Deformation and deflection of machine parts

• Axial and radial shaft displacement

• Abrasion wear and position measurements at thrust bearings

• Thickness of oil films in bearings

• Differential expansion

• Housing expansion, valve position

Product specification: CON021
Rated output 125~800HP; 90~600kw
Number of poles (P) 2, 4, 6, 8
Voltage (v) 2300-6600
Frequency (Hz) 50, 60
Frame number (F #) 315A-450A

The converters are available in different constructions to meet various requirements. Since all converters contain the same electronic circuits, each converter may be operated with each transducer. For the use with standard measuring ranges, converters and / or transducers may be interchanged without new adjustment. Connection of supply voltage and signal output is made via cage clambrespectively screw terminals. The transducer connection is made either by means of a self locking Lemo plug or via cage clamb- respectively screw terminals for transducers with open cable ends. All transducers are provided for combination with the converters for use in explosive ranges (with the former barriers specified for this). The certificate of conformity according to the European standards EN 50014 and EN 50020 is available at epro.
