Product Description
System Overview
The Emerson PR6423/010-040 + CON021 combination integrates a high-precision eddy current displacement sensor with a signal converter for reliable vibration and shaft position monitoring in critical rotating machinery. This configuration ensures accurate measurement of radial vibration, axial shaft displacement, and rotational speed without physical contact. The system is widely used in turbines, compressors, pumps, and other high-speed equipment.
The sensor PR6424/010-120 features a rugged probe with a 10 mm tip diameter and a 12 m cable length (2 m integrated + 10 m extension). The CON021 converter provides stable excitation, signal amplification, and standardized voltage output compatible with Emerson machinery protection systems like AMS 6500 and A6000.

FAQ
Q: Can this sensor be used in high-temperature turbine environments?
A: Yes, the probe operates up to 180°C, suitable for turbine bearings and compressor housings.
Q: Is the sensor output compatible with other monitoring systems?
A: The CON021 converter outputs a standard voltage signal suitable for Emerson AMS 6500/A6000 systems. Third-party systems may require signal adaptation.
Q: What is the maximum cable length for accurate readings?
A: The integrated and extension cable total 12 m. Longer extensions may reduce signal fidelity and require compensation.
Q: How does this model compare to PR6423/010-120?
A: The PR6423/010-040 + CON021 offers similar linearity and frequency response but is optimized for shorter-range, high-precision measurements.
