EPRO PR6423/000 Product introduction
The EPRO PR6423/000 is a high-precision non-contact eddy current sensor designed to measure vibration and displacement of rotating machinery. The following is a detailed description of the product:
Working principle
The EPRO PR6423/000 sensor operates on the eddy current effect. When the sensor is close to the metal conductor, the alternating magnetic field will produce eddy currents on the metal surface, which will produce a secondary magnetic field, which will react on the sensor coil, so that the inductance, impedance and quality factor of the coil will change. By measuring the change of these parameters, the displacement and vibration of the measured object can be measured indirectly.
Product characteristics
Non-contact measurement: the sensor is not in contact with the object to be measured, will not interfere with the object to be measured, and will not affect the measurement accuracy due to wear, suitable for a variety of high-speed rotation and high-precision measurement occasions.
High precision: The ability to accurately measure small displacement and vibration changes, measuring accuracy up to the micron level or even higher.
High reliability: With advanced electronic technology and manufacturing process, it has good stability and anti-interference ability, and can operate reliably in harsh industrial environment for a long time.
Various measuring functions: In addition to measuring vibration and displacement, it can also be used to measure the gap between the rotating part and the fixed part, the eccentricity of the shaft, the bending of the shaft, the wear of the bearing, the thickness of the oil film, the relative thermal expansion of the shaft and the bearing and many other physical quantities.
Wide range of application: suitable for monitoring and protection of various industrial equipment such as turbo machinery, fans, compressors, gear boxes, water pumps, coal lapping machines and so on.
Technical parameter
Measurement range: Generally 1mm to 20mm, the measurement range of different models of sensors may be different.
Thread size: Available in metric or imperial threads such as Φ6mm, Φ10mm and Φ18mm.
Cable options: Different lengths of cables can be selected according to the model, waterproof connectors at the end of the cable or bare wire mode, cables can also be armored or unarmored, 1m cables can be selected with or without connectors.
Applicable temperature: usually -35℃ to +380℃.
Output signal: Generally the AC voltage signal superimposed on the DC voltage is proportional to the shaft vibration, the internal resistance is 100kΩ, and the response time is 15μs.
Accuracy: Linear error varies depending on the type of sensor.
Application field
Rotating machinery monitoring: used to measure the bearing clearance, shaft eccentricity, rotor unbalance, shaft vibration, shaft displacement, key phase, speed, expansion, eccentricity and other parameters of rotating machinery.
Thermal expansion monitoring: In high temperature environments, the coefficient of thermal expansion of parts can be measured, such as monitoring the thermal expansion of rolls during the hot rolling process in a steel mill.
Thickness measurement: It can measure and control the thickness of metal sheet and film, etc., which is widely used in metal processing and film production industry.
Position detection: It is often used for precision positioning on robot and automated assembly lines to ensure the accuracy and consistency of the production process.
Non-destructive testing: can detect defects in metal materials, such as cracks, holes, etc., in aerospace, automotive manufacturing and other industries with high material quality requirements is crucial.
From the above introduction, it can be seen that the EPRO PR6423/000 sensor has significant advantages in high-precision measurement, non-contact measurement and a wide range of applications, and is the ideal choice for industrial equipment monitoring and protection.
