Product Introduction
The Epro PR6426/010-000+CON021/916-160 is a high-performance eddy current displacement sensor developed for precise and reliable non-contact measurement of the distance, position, or vibration of rotating or reciprocating machinery. With a 32mm probe diameter, this sensor is designed for heavy industrial use, including harsh and demanding operating conditions such as those found in turbines, compressors, pumps, and motors.
Manufactured by Epro, now part of Bently Nevada / Baker Hughes, the PR6426 series is widely respected for its superior signal fidelity, mechanical robustness, and compatibility with industrial monitoring systems. The sensor works in conjunction with the CON021/916-160 converter, which processes the raw analog signal for integration into condition monitoring systems.
This eddy current sensor is part of a trusted and proven series used globally for machine protection and predictive maintenance in power generation, oil & gas, and heavy industry environments.
