Application-Oriented Scenarios
The PR6423/003-030-CN combined with the CON021 signal converter is purpose-built for precision shaft monitoring in critical rotating machinery. It is widely used in steam turbines, gas turbines, compressors, and large industrial pumps where continuous displacement and vibration measurement are essential for safe operation.
In power generation and petrochemical industries, this sensor system enables accurate tracking of shaft position, eccentricity, and dynamic vibration behavior. Its ability to operate under extreme temperatures and harsh environments makes it ideal for high-reliability installations where equipment failure is not acceptable.
Performance & Design Advantages
A key strength of this configuration is the integrated measurement chain. The PR6423 probe captures high-resolution displacement data, while the CON021 converter ensures precise signal conditioning and stable output for control systems.
The system delivers excellent linearity and sensitivity (typically 8 V/mm), enabling detection of micron-level shaft movement. This is critical for early fault diagnosis such as imbalance or misalignment.
Its non-contact measurement principle eliminates mechanical wear, significantly extending service life and ensuring consistent accuracy over time. Additionally, the IP66-rated sensor design provides strong resistance to oil, dust, and industrial contaminants.
Another major advantage is its high-frequency response (up to 20 kHz), allowing accurate capture of fast transient events in high-speed rotating equipment.
