The PR6423/003-130 CON021 is an eddy current transducer system used for non-contact vibration and displacement measurement in industrial rotating machinery. Often used for turbines and compressors, this system (sensor + converter) measures radial shaft vibration or axial position, typically providing high-frequency response and harsh environment resistance.
Utilizes hermetic sealing technology
Provides a wide frequency response of 0-20,000 Hz
Fully compliant with API 670 and DIN 45670 standards
Sensor Signal Converter designed for critical turbo machinery applications such as steam, gas and hydro turbines, compressors, pumps and fans to measure radial and axial shaft displacement, position, eccentricity and speed/key.

Thermal Power Generation
Monitoring shaft vibration and axial displacement of large steam turbine-generator sets to prevent rotor-stator friction.
Petroleum Refining
Monitoring the operation of critical centrifugal compressors and high-temperature oil pumps to ensure continuous production safety.
Natural Gas Pipeline
Installed on gas turbines at compressor stations along long-distance gas pipelines to measure shaft speed and phase.
Steel & Metallurgy
Monitoring bearing vibration of blast furnace blowers and large rolling mill drive motors to prevent unplanned downtime.
Chemical & Fertilizer
Monitoring axial displacement and eccentricity of ammonia synthesis units and reciprocating compressors.
Water & Wastewater
Protection for high-power submersible pumps and motor sets in urban flood control and drainage systems.
The core of using the PR6423/003-130 eddy current sensor lies in precise installation control and physical protection of the signal link. During installation, the initial gap between the probe tip and the shaft surface must be accurately set by monitoring the CON021 converter's output voltage to ensure it stays within the linear range (typically around -10V DC). Furthermore, it is strictly prohibited to cut or extend the integrated 8.0-meter cable, as the system impedance is precisely calibrated for this specific length; any alteration will result in significant measurement errors. Additionally, ensure the mounting bracket is rigid enough to eliminate self-vibration and use insulating sleeves to protect connectors from oil ingress or ground loop interference, thereby guaranteeing reliable monitoring data on critical machinery such as turbines and compressors.
This is an industrial-grade non-contact eddy current displacement sensor system.
What is the core function of PR6423/003-130 CON021?
Its core functions are shaft vibration, axial position, and speed monitoring.
How to properly install PR6423/003-130 CON021?
The key is setting the initial gap voltage. Adjust the thread depth until the CON021 output voltage reaches the linear midpoint (typically around -10V DC) to ensure full measurement range.
What is the linear range of PR6423/003-130 CON021?
This 8mm sensor system typically offers a linear range of 2.0 mm (80 mils), with a standard sensitivity usually at 8 V/mm.
What type of output signal does the CON021 converter provide?
It outputs a negative voltage signal (e.g., 0 to -20V DC) proportional to the gap, where the DC component represents static position and the AC component represents dynamic vibration.
