The overall structure of the equipment is compact, with high operational reliability, and possesses excellent anti-electromagnetic interference ability and environmental adaptability. It can operate continuously in complex industrial sites for a long time. It can accurately capture the amplitude of vibration and the subtle changes in the state, and predict various mechanical faults such as rotor imbalance, bearing wear, base loosening, and component collision and wear in advance, effectively avoiding equipment damage and sudden shutdowns. It is an important monitoring unit for ensuring the stable operation of various heavy-duty power units. Basic Information

This product belongs to the 3300 modular monitoring system series. The complete model clearly indicates the number of channels, hardware configuration and functional specifications. The equipment adopts an industry-standard plug-in rack structure, and its size is fully compatible with the common rack of the 3300 series. Installation, disassembly, on-site calibration and later maintenance operations are simple and convenient. The wiring is neat on-site, and the wiring process is simple. The product is strictly developed and produced in accordance with industrial electrical safety and electromagnetic compatibility standards. The body shell has the protective effect of dust prevention and slight mechanical shock resistance, and can operate normally in conventional working environments such as industrial cabinets, control rooms, and production equipment areas. The module adopts a unified standard power supply method for the series, and can be coordinated with the same series power module to work together. The electrical interfaces are all standardized, and it can be quickly connected to the entire monitoring, alarm and control circuit. The system has excellent compatibility and expansion capabilities.

Function and Positioning

This module is a dual-channel independent monitoring unit. The two channels are electrically isolated from each other, and their working states do not affect each other. It can simultaneously connect two sets of external sensing signals. The equipment can complete a series of processing tasks such as receiving, amplifying, filtering, shaping and data conversion of the original vibration signals, and continuously collect the vibration operation parameters of mechanical equipment. The standard industrial signals processed can be synchronously transmitted to the upper control system, data recorder, on-site display instrument, etc., to achieve real-time display, long-term storage and historical operation data traceability of the monitoring data. The module is equipped with multiple levels of customizable alarm thresholds and intelligent fault judgment logic, which can effectively identify various fault states such as vibration over-limit, sensor abnormalities, circuit breakers, signal distortion, etc. Once the monitoring value exceeds the preset safety range, the module will immediately output an alarm signal to alert the maintenance personnel to promptly identify and eliminate potential hazards. The product is mainly applied in daily condition inspection of units, early fault warning, and equipment health management scenarios, providing all-weather vibration safety protection for continuously operating rotating mechanical equipment.

Core Performance Parameters

The module is compatible with the vibration sensors provided by Benelco, with high signal acquisition sensitivity, capable of effectively filtering out on-site noise, harmonics, and electromagnetic interference generated by large power motors, frequency converters, and high-voltage cables, ensuring pure and stable signal transmission. The measurement range of the dual channels is designed for the mainstream vibration monitoring needs of large and medium-sized industrial equipment, with excellent measurement linearity and high repeatability measurement accuracy. The data drift during the long-term uninterrupted operation of the equipment is extremely low, and the monitoring results are accurate and stable. The electromagnetic compatibility indicators of the entire system meet the requirements of harsh industrial environments and can adapt to strong electromagnetic interference sites. The equipment supports 7×24-hour continuous operation and has an average fault-free working time reaching the standards of high-end industrial equipment. The signal output is a common industrial standard signal, which can seamlessly connect with various mainstream industrial control equipment, alarm units and data acquisition terminals. The working temperature and humidity range of the equipment covers the conventional industrial indoor and cabinet environments, and the environmental tolerance is strong.

General Adaptable Accessories

The front signal acquisition end can be used with 3300 series vibration sensors, extension cables, signal transfer components, etc., to ensure the integrity of signal acquisition and transmission. On-site installation can be combined with shielded signal cables, standard wiring terminals, module fixing clips, etc., to meet the wiring, wiring and equipment fixation requirements. In terms of system integration, it can be flexibly combined with 3300 series system racks, power supply modules, shaft displacement monitoring modules, speed monitoring modules, relay output modules, communication modules, etc., to build an integrated comprehensive monitoring system according to the on-site monitoring points and functional requirements. The module interfaces, wiring accessories and vulnerable components all adopt the 3300 series general specifications, and spare parts procurement and replacement are convenient. Daily maintenance, parameter calibration can be completed using conventional industrial electrical tools.
