3300/14-01-20-01 Product Description Product Introduction

3300/14-01-20-01 is a Bechtel 3300 series dual-channel vibration monitoring module. As the core hardware of the industrial rotating machinery condition monitoring system, it is specially designed for harsh industrial environments. The product integrates a high-precision signal processing circuit, mainly responsible for collecting and analyzing the vibration parameters of the equipment. It features strong stability, outstanding anti-interference ability, and high integration. It can operate continuously for a long time, monitor the vibration status of the equipment in real time, promptly capture abnormal vibration signals, and is an important monitoring unit for ensuring the safe and stable operation of large-scale units and predicting equipment failures in advance. Basic Information

This product belongs to the 3300 modular monitoring system. The complete model clearly specifies the hardware configuration, channel specifications and functional parameters. The equipment adopts a standard rack-mounted modular structure, with dimensions compatible with the universal installation rack of the 3300 series. The plug-in design makes installation, disassembly, debugging and later maintenance work more convenient. The on-site wiring is neat and the operation difficulty is low. The entire machine strictly follows the relevant norms of industrial electrical safety and electromagnetic compatibility. The enclosure has the ability to prevent dust and slight impact, and can adapt to the regular working conditions of industrial computer rooms, production device areas, etc. It adopts industrial standard power supply mode and can be combined with the same series power module to work collaboratively. The electrical interface is standardized and can be quickly connected to the entire monitoring control loop.

Function and Positioning

This module is positioned as a dual-channel vibration-specific monitoring unit, capable of simultaneously connecting two independent vibration sensor signals. The equipment can receive, amplify, filter, shape and process the original sensing signals, accurately collecting key parameters such as radial vibration and shell vibration of the equipment. The processed standard signals can be transmitted to the upper-level control system, data recorder, on-site display instrument, etc., to realize real-time display, historical storage and operation traceability of vibration data. The module is equipped with multiple-level alarm thresholds and intelligent judgment logic, supporting the identification of various working conditions such as vibration exceeding limits, abnormal signals, and sensor failures. When the monitoring data deviates from the safe range, an alarm signal is immediately output to remind the maintenance personnel to conduct hazard checks, effectively avoiding problems such as component wear, unit shutdown, and equipment damage caused by abnormal vibration, and is widely used in equipment daily condition inspection, early fault warning, unit operation control and other scenarios.

Core Performance Parameters

The module's signal input is compatible with the same series eddy current sensors and speed sensors, with high signal pickup sensitivity, and can effectively filter out on-site interference. The dual-channel measurement is independent and does not affect each other, and the measurement range is adapted to the mainstream large and medium-sized industrial equipment application requirements. The linear accuracy and repeatability accuracy both reach the industrial high-end standards, and the data drift under long-term continuous operation is extremely small. The equipment has excellent electromagnetic compatibility performance, capable of resisting electromagnetic interference generated by large-power motors, frequency converters, high-voltage cables, etc., ensuring the authenticity and reliability of the monitoring data. It supports 7×24-hour continuous operation, and the average fault-free operation time meets the requirements of industrial continuous production. The output signal is a universal industrial standard signal, with strong compatibility, and can be connected to various mainstream industrial control equipment, alarm devices and data acquisition terminals. The working temperature and humidity range is adapted to industrial cabinets, indoor device areas and other regular environments, with good environmental adaptability.

General Compatible Accessories

The front end can be equipped with 3300 series vibration probes, extension cables, preamplifiers and other sensing components to ensure the integrity and accuracy of signal collection. On-site installation can be combined with standard terminal blocks, dedicated shielded signal cables, module fixing clips, etc., to meet wiring and fixation requirements. At the system level, it can be combined with 3300 series system racks, power modules, speed monitoring modules, shaft displacement monitoring modules, relay output modules, communication modules, etc., to build a complete monitoring system. It can be flexibly expanded and configured according to the on-site monitoring points, functional requirements. The equipment interfaces and vulnerable parts all adopt series general specifications, 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, large heavy industry, etc., and is compatible with steam turbine generators, gas turbines, centrifugal compressors, large blowers, industrial large pump sets, smoke gas turbines, gearboxes, and other various large and medium-sized rotating mechanical equipment. It is mainly installed in places such as the main plant buildings of power plants, chemical production areas, metallurgical power workshops, and power machine rooms of industrial enterprises, providing dual-channel vibration monitoring and comprehensive safety protection for heavy-duty power equipment used in continuous operations.
