3300/12-01-22-03 Product Description

Product Overview

3300/12-01-22-03 is a part of the Bently 3300 series axial displacement monitoring module, which is the core module of the industrial rotating machinery condition monitoring system. This product is built based on high-precision signal processing technology and is specially designed for complex industrial working conditions. It focuses on monitoring parameters such as axial displacement and shaft runout of rotating shafts. The equipment has a high integration degree and strong operational stability. It has excellent electromagnetic protection and environmental adaptability and can work continuously online for a long time. It can accurately capture abnormal changes in the position of the shaft system and give early warnings of faults such as shaft friction, collision and wear, and displacement exceeding the standard, effectively protecting the safety of the main equipment. It is an indispensable monitoring device in the operation and maintenance system of large power units. Basic Information

This product belongs to the 3300 modular monitoring system. The complete model corresponds to specific channel configuration, hardware parameters and functional specifications. The entire machine adopts an industry-standard rack-mounted plug-in structure, and its size is fully compatible with the universal installation rack of the 3300 series. The installation, disassembly, on-site debugging and later maintenance processes are simple and efficient, with a neat wiring layout. The product is produced in strict accordance with industrial electrical safety and electromagnetic compatibility standards. The enclosure has the ability to prevent dust and minor mechanical collisions, and can operate stably in conventional industrial environments such as industrial cabinets, device rooms, and on-site control rooms. The module adopts an industrial standard power supply mode and can be used in conjunction with power supply modules of the same series. The electrical interfaces are unified and standardized, and it can be quickly connected to the entire monitoring control loop.

Functions and Positioning

This module is a dedicated shaft displacement monitoring unit, responsible for connecting the front-end sensing equipment, receiving, amplifying, filtering, shaping and numerical conversion of the original signals, and accurately collecting key operating parameters such as the axial displacement and instantaneous wobble of the rotating mechanical shaft. The module can upload the processed standard signals to the upper-level control system, data recorder, on-site display instrument, and realize real-time display, historical storage and operation status traceability of the monitoring data. The device is equipped with multiple levels of customizable alarm thresholds and fault diagnosis logic, which can identify various working conditions such as displacement over-limit, signal loss, sensor failure, and line abnormalities. When the monitoring parameters deviate from the safe range, it immediately outputs an alarm signal to alert the maintenance personnel to promptly identify and eliminate potential hazards. It is mainly applied in daily condition inspection of units, early fault warning, and control of shaft system conditions, avoiding equipment wear, shutdown and even safety accidents caused by abnormal shaft displacement.

Core Performance Parameters

The module is compatible with the signals input of the same series eddy current sensors, has high signal recognition sensitivity, and can effectively filter out on-site noise and electromagnetic interference signals. The measurement range is optimized for large and medium-sized rotating mechanical shaft displacement monitoring conditions, and the linearity and repeatability measurement accuracy both reach the industrial high-end standards, with minimal data drift under long-term continuous operation. The equipment has excellent electromagnetic anti-interference performance, can resist the electromagnetic influence generated by large-power motors, frequency converters, and high-voltage power supply lines, and ensures the authenticity and reliability of the monitoring data. It supports 7×24-hour uninterrupted continuous operation, and the average fault-free operation time meets the requirements of industrial continuous production. The signal output is in a universal industrial standard format, has strong compatibility, and can be connected to various mainstream industrial control equipment, alarm units and data acquisition terminals. The working temperature and humidity range is adapted to the conventional indoor cabinet environment, and the environmental tolerance performance is good.

General Adaptable Accessories

The front end can be equipped with 3300 series eddy current probes, signal extension cables, preamplifiers and other dedicated sensing components to ensure the quality of signal collection and transmission stability. The on-site installation can be combined with shielded signal cables, standard terminal blocks, module fixing clips and other basic auxiliary materials to meet wiring, connection and equipment fixation requirements. At the system level, it can be combined with 3300 series system racks, power supply modules, vibration monitoring modules, speed monitoring modules, relay output modules, communication modules, etc. to build a complete monitoring system, and can be flexibly expanded and combined according to the on-site monitoring points and functional requirements. The device interfaces and vulnerable parts all adopt the universal specifications of this series, and spare parts procurement and replacement are convenient. Daily maintenance can be completed using conventional industrial electrician tools.

Applicable Equipment Fields

The product is widely used in thermal power generation, petrochemicals, metallurgy, coal chemical industry, heavy equipment manufacturing and other industries, and is compatible with various large and medium-sized rotating mechanical equipment such as steam turbine generators, gas turbines, centrifugal compressors, large fans, flue gas turbines, high-pressure pump sets, large gear sets, etc. It is mainly installed and used in places such as the main plant buildings of power plants, chemical production areas, metallurgical power workshops, and power machine rooms of industrial and mining enterprises, providing 24-hour axial displacement monitoring and safety protection for continuous operation heavy power equipment.
