The entire machine is produced in strict accordance with industrial mechanical equipment protection standards, undergoes full-scale calibration during factory production, and has simple installation, gap adjustment, maintenance, and replacement procedures, suitable for various industrial on-site monitoring environments.

Function and Position

This sensor serves as the system signal acquisition terminal, mainly achieving non-contact dynamic measurement. During operation, it maintains a standard installation gap with the measured metal rotating shaft, using the eddy current effect to real-time sense the position deviation and vibration amplitude of the shaft body, converting the physical displacement signal linearly into an analog electrical signal, and transmitting it through a dedicated cable to the preamplifier and subsequent monitoring modules. The equipment has no physical contact throughout the process, will not cause scratches or wear on the measured shaft surface, and is suitable for various operating conditions such as normal operation, start-stop, and load changes of the unit. In addition to basic parameter collection, it can be combined with the backend system to achieve functions such as vibration anomaly recognition, shaft movement monitoring, and rotor condition diagnosis. The product is mainly used for data collection at monitoring points such as large rotating machinery bearings and shaft ends, performing condition perception and raw signal transmission, providing continuous and real basic signals for fault warning, parameter interlock, and equipment operation analysis.

Core Performance Parameters

The product has an adequate measurement linear range, excellent full-scale output linearity, low measurement error, and high repeatability of detection. Temperature drift and time drift are strictly controlled, and the measurement accuracy will not show significant deviation under long-term continuous operation. The multi-layer shield structure can effectively resist electromagnetic interference from large-power motors, frequency converters, and high-voltage lines, eliminating signal noise, jumps, and distortion. The dynamic response is fast, capable of accurately capturing high-frequency vibrations and instantaneous displacement changes of the rotating shaft, with extremely low signal transmission delay. The mechanical performance is stable, with the probe resistant to wear, high and low temperatures, and medium corrosion, and the cable resistant to bending and stretching. The service life is long. The electrical insulation performance meets standards, the circuit insulation is reliable, and it has good anti-electric leakage and anti-short-circuit capabilities. The working temperature and humidity range covers typical environments such as industrial equipment cavities, bearing seats, and on-site cabinets, with strong environmental adaptability. The overall load and signal output characteristics match the standards of the rear-end monitoring equipment, meeting the requirements for long-distance stable signal transmission.

General Adaptable Accessories

Mechanical accessories such as locking nuts, anti-loosening washers, fixed brackets, and positioning sleeves can be used for installation and adjustment, completing the fixation, gap adjustment, and anti-loosening positioning of the sensor. The signal link can be equipped with extension cables, adapter connectors, and sealing connectors to achieve line extension and interface sealing protection. System integration must be used with the 32000 series preamplifier, and can be connected to vibration monitoring modules, shaft displacement monitoring modules, racks, power modules, etc. to form a complete monitoring system. Wiring can use cable protectors, fixing clips, waterproof connectors, etc., to organize and protect the lines. The product interfaces, connection components, and general wear parts are of 32000 series standard specifications, making spare parts procurement and replacement convenient. Daily gap calibration, appearance inspection, and line testing can be completed using conventional measuring tools and industrial electrician tools.

Applicable Equipment Domains The product is widely applied in industries such as thermal power generation, petrochemicals, coal chemical industry, metallurgy, oil and gas extraction, heavy equipment manufacturing, etc. It is mainly installed on large and medium-sized rotating mechanical equipment such as steam turbine generators, gas turbines, centrifugal compressors, flue gas turbines, large draft fans, high-pressure industrial pump sets, heavy-duty gearboxes, etc. It is typically installed at monitoring points such as equipment bearing seats, shaft ends, and casing. It collects vibration and displacement parameters online, and cooperates with the backend monitoring system to achieve condition monitoring, fault early warning, and safety interlock protection, ensuring the long-term safe, stable, and continuous operation of core production equipment.
