Product Description

Description

The Emerson PR6423/010-010 with CON021 is a non-contact sensor and signal converter system engineered for critical turbomachinery applications, including steam, gas, and hydro turbines, compressors, gearboxes, pumps, and fans. The PR6423 eddy current sensor detects radial and axial shaft dynamic displacement, position, eccentricity, and speed. The CON021 sensor signal converter processes these proximity measurements into stable output signals suitable for monitoring industrial machinery health.

Features

Non-contact eddy current measurement principle for precise displacement tracking
High-frequency response suitable for dynamic machine diagnostics
Armored cable protection for enhanced mechanical durability in industrial environments
Flexible mounting options with included installation screws
Transducer connection utilizing a self-locking plug interface

Applications

Radial and axial shaft dynamic displacement monitoring
Shaft position and eccentricity measurement
Speed monitoring and key pulse detection
Turbomachinery protection systems (turbines, compressors, fans, pumps)

Installation Guidelines

Ensure the minimum bending radius for the standard cable is at least 25 mm, and at least 35 mm for the armored cable.
Maintain proper probe gap alignment using the target initial air gap specification of 0.5 mm for standard measurement ranges.
Mount the signal converter within an environment matching its IP20 rating, securing it firmly with the provided M5x20 screws.
Use a safety barrier or current limiting device when deploying the system into hazardous environments requiring intrinsic safety.
