It can accurately capture the micro displacement fluctuations, slow shifts, and abnormal runout hazards of the unit's shaft system, providing continuous and precise on-site monitoring data for daily operation monitoring, load variation analysis, fault prediction, preventive maintenance, and basic safety warning. It is widely used in continuous industrial production fields such as power, chemical, oil and gas, and metallurgy.

II. Product Basic Characteristics

This product is a standard 3300 series axial displacement monitoring module with no special customized functions. It has extremely strong universality. The equipment adopts a standard industrial control cabinet rail-mounted installation structure, with a compact overall volume, small occupation of the cabinet space, simple installation, wiring, maintenance, and module replacement operations, and is compatible with various standard industrial instrument cabinets and unit control cabinets. The entire machine strictly follows industrial electrical safety standards and electromagnetic compatibility design specifications, can adapt to the complex electromagnetic environment of industrial sites, regular temperature and humidity changes, and equipment operation vibration conditions, with excellent environmental adaptability.

The equipment has undergone full-scale accuracy calibration, linearity detection, signal stability testing, and long-term aging tests before leaving the factory. The measurement linearity, data repeatability, and long-term operation stability all meet the standards of industrial precision monitoring instruments. After on-site installation, no complex parameter setting is required. Just matching the unit's basic parameters to set thresholds is enough to put it into normal operation. The mechanical size, electrical interface, and signal protocol of the module are fully compatible with all products of the 3300 series, and can be freely combined and assembled with power module, vibration monitoring module, and communication module. It supports system expansion, renovation of old equipment, module interchange and replacement, with universal spare parts and convenient operation, and can long-term stably adapt to the continuous operation requirements of industrial units.

III. Core Function Characteristics

This module adopts a dual-channel independent monitoring architecture. The two monitoring channels are independent and do not interfere with each other. It can simultaneously connect two 3300 series electro-vortex displacement sensors to simultaneously collect the original signals of the rotor's axial displacement, achieving dual-channel independent monitoring, effectively enhancing the integrity and reliability of shaft system monitoring. The module is equipped with a dedicated signal processing circuit, which can automatically complete signal amplification, power frequency filtering, noise reduction, linear correction, and analog-to-digital conversion processing. It can effectively filter out electromagnetic interference generated by frequency converters, high-voltage motors, and power equipment in the field, eliminate invalid interference signals, accurately restore the true axial displacement state of the unit's rotor, and ensure stable, true, and undistorted monitoring data. The equipment has standard hierarchical alarm and loop self-check functions. It supports customizing warning and danger alarm thresholds according to the unit's design operating conditions. It can accurately distinguish three operating states: normal operation, slight abnormality, and over-limit fault. When there is an abnormal shift or over-limit operation of the axial displacement of the unit, the local status indicator light of the equipment updates the status in real time, and simultaneously outputs standard analog signals and switch quantity alarm signals. It can directly connect to DCS, PLC, and unit monitoring systems to achieve local status indication, remote data upload, and abnormal alarm functions. The module is equipped with a built-in sensor fault self-check mechanism, which can actively identify circuit abnormalities such as probe disconnection, line faults, and signal loss, and promptly report monitoring system failures to prevent monitoring failure and data distortion, ensuring the stable and reliable operation of the entire monitoring circuit.

IV. Equipment Performance Parameters and Advantages

This module is compatible with industrial standard DC power supply specifications and the power supply environment of mainstream industrial instruments. The overall power consumption is low, and the temperature rise during long-term continuous operation is stable. There are no problems such as overheating shutdown, performance attenuation, or zero-point drift. The operational stability is excellent. The signal input circuit is specially designed to match the 3300 series eddy current displacement sensors, with high signal adaptability, sensitive response, and good measurement linearity. It can accurately capture micro-micron-level displacement changes of the shaft system, meeting the process requirements of precise monitoring of large-scale units. The standard range of the equipment is compatible with the axial displacement monitoring conditions of domestic mainstream steam turbine units and compressor units, covering all working conditions such as steady-state operation, start-stop switching, and load fluctuations.

The equipment data refreshes quickly, can synchronously and in real time reflect the dynamic changes of the shaft system, with no delay or lag in data update, and accurately reproduces the instantaneous operating state of the unit. The entire machine has been optimized with strict electromagnetic compatibility design, possessing excellent anti-electromagnetic interference, anti-vibration, and environmental fluctuation resistance capabilities, and can work continuously and stably in complex industrial environments. The equipment has good dust-proof, moisture-proof, and aging resistance performance, with a long average trouble-free operation time, fully meeting the strict industrial conditions requirements of continuous operation without interruption for key units throughout the year.

V. Compatible Adaptation System

This module needs to be combined with the specific dedicated components of the 3300 series to form a complete monitoring circuit. Standard compatible components include the same series eddy current axial displacement probes and dedicated extension cables. The impedance matching of the entire sensing circuit is precise, and the signal transmission loss is low, which can maximize the overall measurement accuracy and signal stability of the equipment. On-site, industrial shielded signal cables can be used to complete the long-distance transmission of analog data and alarm signals, and compatible standard cabinet rails, terminal blocks, and other general installation accessories can be used. The installation is standardized and highly compatible.

The module can be freely integrated and assembled with the 3300 series full-range power units, various vibration monitoring units, and communication expansion units. It can be flexibly built into a centralized unit monitoring system based on the number of monitoring points at the site, supporting later point expansion, system modification, and function upgrade. The market availability of all compatible accessories is large, procurement is convenient, and the universality and interchangeability are extremely high, effectively reducing equipment spare parts reserves, daily operation and system modification costs.
