EPRO PR6423/002-030+CON021 Eddy Current Sensor

PR6423/002-030+CON021 is a non-contact vibration/displacement measurement system manufactured by the EPRO brand under Emerson. This combination is a key component of the industrial-grade mechanical monitoring system. It can achieve real-time and precise measurement of important dynamic mechanical parameters such as shaft vibration, displacement, eccentricity, and rotational speed. It is widely used in online monitoring and protection of turbines, compressors, generator sets, pumps, fans, gearboxes, and other critical rotating equipment. It is a typical sensing subsystem of a highly reliable equipment condition monitoring system.

PR6423/002-030+CON021 system consists of two main components:
** PR6423/002-030: Eddy Current sensor probe, used for high-precision measurement of displacement, vibration, and dynamic parameters in rotating machinery;
** CON021: The accompanying signal converter, used to process, filter, amplify,fy, and standardize the output signal from the sensor, making it suitable for industrial monitoring and control systems.

The eddy current sensor (Eddy Current Sensor) measures non-contact displacement/vibration using the principle of electromagnetic induction:
✔ When the induction coil approaches a conductive metal target (such as a rotating shaft or measuring ring), eddy currents are generated within the target;
✔ These eddy currents will alter the impedance of the coil;
✔ The sensor detects the impedance change and converts it into an electrical signal, which is proportional to the distance change between the probe and the target.

CON021

CON021 is a signal conversion amplifier/processor that is compatible with the PR6423 series sensors.

CON021 processes sensor signals in the following ways:
✔ Signal conditioning: including filtering, noise suppression, and amplitude amplification;
✔ Linearization and gain adjustment: ensuring that the output signal is proportional to the input displacement;
✔ Standard signal output: providing measurable measurement data in industrial standard voltage or current form (e.g., -4 V to -20 V, etc.).

✔ Location Selection:P R6423/002-030 Install near the shaft of the mechanical equipment where vibration is most pronounced;
✔ Installation Method: The sensor is typically fixed using M10×1 threads and the corresponding mounting bracket and measuring rig.g;
✔ Cable Wiring: High protection requirements; avoid parallel wiring with strong electrical interference sources;

Used in conjunction with the CON021 signal converter, it is convenient to realize the signal processing and output of the sensor. It supports a variety of configuration options and can be flexibly configured and adjusted according to different application scenarios.

When selecting a sensor, you need to consider factors such as range, resolution, frequency response, operating temperature, and protection level to ensure that the sensor can meet actual application requirements. We provide selection and technical support.
