K9000/9000XL series eddy current sensor——Eddy current displacement and vibration sensors

Eddy current sensors can statically and dynamically measure the distance between the measured metal conductor and the probe surface in a non-contact, high linearity, and high-resolution manner. It is a non-contact linearization measurement tool. Eddy current sensors can accurately measure the static and dynamic relative displacement changes between the measured object (which must be a metal conductor) and the probe end face. In the state analysis, vibration research, and analysis measurement of high-speed rotating machinery and reciprocating motion machinery, multiple parameters of rotor vibration state can be continuously and accurately collected for non-contact high-precision vibration and displacement signals. Such as radial vibration, amplitude, and axial position of the shaft.

Among all the fault symptoms related to the mechanical state, mechanical vibration measurement is powerful because it contains information on amplitude, phase, and frequency simultaneously.

Another advantage of mechanical vibration measurement is that it can reflect all mechanical damages and is easy to measure.

From the theoretical analysis of rotor dynamics and bearing science, the motion state of large rotating machinery mainly depends on its core - the shaft. Eddy current sensors can directly and non-contact measure the state of the shaft, providing key information for early determination of mechanical problems such as rotor imbalance, misalignment, bearing wear, shaft cracks, and friction.

Eddy current sensors have been widely used in online monitoring and fault diagnosis of large rotating machinery due to their long-term reliability, wide measurement range, high sensitivity, high resolution, fast response speed, strong anti-interference ability, resistance to oil and other media, and simple structure.

HNYC-32Q Intelligent Vibration Monitor

The HNYC-32Q intelligent vibration monitoring instrument is mainly suitable for fields such as power generation, steel, metallurgy, and chemical engineering. It continuously monitors and measures the bearing vibration (absolute vibration) and shaft vibration (relative vibration) of various rotating machinery. In this type of machine, the shaft vibration can be transmitted to the machine shell more frequently. Therefore, the monitoring instrument can be equipped with a magnetic electric speed sensor for continuous measurement and protection of rotating machinery. Special attention should be paid to the installation of the sensor to avoid reducing the amplitude of the sensor, changing the frequency effect, or generating signals that cannot represent the true vibration of the machine. For situations where a large number of vibration points need to be measured, such as motors, compressors, fans, etc., it is convenient for users to analyze and maintain the working conditions of the machine. Equipped with current output, it can be used for connecting external recorders and microcomputers.

This device is digitized, with good stability, high accuracy, simple operation, and convenient and reliable maintenance. The friendly human-machine dialogue interface makes this product at the domestic level.
