II. Basic Information

This product is manufactured by Bentley Nevada and belongs to the 3300 industrial condition monitoring series. The model is 3300/16-02-01-03-00-00-00. The equipment type is a dual-channel radial vibration and shaft clearance integrated monitor. The core functions include two-channel vibration amplitude measurement, gap voltage collection, calculation of the average position of the shaft, multi-level alarm output, customized signal transmission, fault self-diagnosis, and remote parameter management. The equipment is compatible with 3300 XL, 7200 series eddy current probes and their accompanying preamplifiers. The standard probe sensitivity is 200mV/mil, and it can be matched with mainstream sensing accessories in industrial sites. The entire machine is installed in a 19-inch standard frame, which can seamlessly fit into the same series monitoring cabinets. The product complies with CE electromagnetic compatibility standards and can operate continuously in industrial sites with high dust content, complex electromagnetic environments, and large temperature and humidity fluctuations.

III. Functions and Positioning

The module is equipped with two completely isolated independent measurement channels. The signals between the channels do not interfere with each other. It can simultaneously monitor the radial vibration in the X and Y directions of a single equipment or conduct parameter monitoring for two different rotating equipment separately. The two sets of data are independently calculated, and the alarm and output logic are independent. While detecting the vibration amplitude, the equipment continuously collects the gap voltage between the shaft and the bearing and converts it into the average operating position of the shaft, achieving dual monitoring of vibration and shaft system position, and providing a comprehensive feedback of the overall operating condition of the rotor and bearing.

The equipment is equipped with a warning and danger two-level alarm mechanism. The alarm threshold and alarm delay of each channel can be flexibly configured through the local panel or the upper-level monitoring software. When the monitoring parameters exceed the preset limit, the corresponding status indicator light on the panel lights up, and it drives the relay to output a switch signal, which can be connected to the on-site sound and light alarm device and the unit interlock system to achieve hierarchical safety protection. The module supports single-channel or dual-channel bypass functions. During sensor calibration, line maintenance, and equipment maintenance, it can temporarily shield the alarm output without affecting the normal operation of other functions of the system, ensuring the uninterrupted operation of the entire monitoring system.

An advanced fault self-diagnosis circuit is built-in, which can detect sensor breakage, line short circuit, abnormal input signals, and hardware faults of the module itself. When an abnormal state occurs, the operation indicator light goes out, promptly alerting the maintenance personnel to carry out fault troubleshooting. This model is equipped with a customized multi-channel signal output interface of 03 specification, which can simultaneously connect multiple automated control systems to meet the data collection requirements of complex sites. The equipment is equipped with a sensor signal buffer output interface, which can be externally connected to oscilloscopes, data acquisition instruments, etc. for on-site signal verification, equipment debugging, and in-depth fault analysis. This model has no industry-specific certification and no built-in safety barrier. It is a standard customized output basic version.

IV. Core Performance Parameters

The input signal of the equipment is the gap voltage output by the eddy current preamplifier. The reference voltage is -24V DC. The two input channels adopt high input impedance design to effectively avoid signal attenuation during transmission. The frequency response is divided into two working modes. The high-frequency mode has a frequency range of 4Hz to 4000Hz, suitable for various high-speed rotating mechanical equipment; the low-frequency mode has a frequency range of 1Hz to 600Hz, suitable for low-speed units. The low-frequency mode is not recommended for equipment with an acceleration rate exceeding 1000rpm/s, to prevent monitoring data distortion.

The full-scale range of vibration measurement for this model is 0 to 125 micrometers peak-to-peak, with a measurement accuracy of ±1% of the full scale. The small-scale design has higher monitoring accuracy. The measurement range of gap voltage is -2V to -22V DC, with a voltage measurement accuracy of ±0.1V. The display resolution of the equipment panel is 0.1 micrometers and 0.1V DC, with clear and precise readings. The power supply can be selected as -18V DC or -24V DC. The module has an independent current-limiting protection circuit, and the maximum power consumption of the entire machine does not exceed 5W. The power supply voltage fluctuates within the range of ±10% of the rated value, and the equipment can maintain stable operation.

The alarm system is divided into two levels: warning and danger. Each channel is independently configured. The rated parameters of the relay contacts are 24V DC and 1A. It supports the switching between normally open and normally closed modes. The alarm delay time can be programmed within the range of 0 to 10 seconds, effectively filtering instantaneous interference signals and reducing the probability of false alarms. The customized output circuit signal transmission is stable, and it is compatible with various industrial acquisition devices.

In terms of environmental adaptability, the normal operating temperature range of the equipment is -40℃ to +70℃, the storage temperature range is -52℃ to +105℃, the applicable relative humidity is 5% to 95%, and the operating environment requires no condensation. The front of the equipment is equipped with an LED digital display screen, which can freely switch to view the vibration values and gap voltages of the two channels. It is also equipped with independent status indicator lights such as running, bypass, warning, and danger. The integrated RS-485 communication interface can be connected to the system host to complete remote parameter configuration, real-time data reading, and alarm status monitoring.

VII. Installation and Maintenance Key Points

The equipment is installed in a 19-inch standard rack. During assembly, sufficient spacing is reserved between modules to ensure ventilation and heat dissipation, and to prevent accumulated temperature from affecting the operating performance of the equipment. This model is a small-range high-precision monitoring module. During wiring operations, strictly distinguish between A and B signal channels, positive and negative power poles, various output terminals and communication terminals, and connect according to the marking specifications to avoid incorrect connections, reverse connections, which may cause measurement deviations or equipment damage. It is recommended to complete the channel accuracy calibration using the original factory standard probes and calibration tools every six months, strictly follow the original factory calibration process, and lock the parameters after calibration to prevent unauthorized personnel from modifying the settings.

During daily operation and maintenance， keep the equipment panel and internal cabinet clean， prevent dust and oil from invading the module interior， regularly check all wiring terminals， promptly tighten loose lines to avoid poor contact causing signal jumps or data distortion. When the equipment triggers fault prompts or abnormal alarms， follow the sequence of first checking the sensors and connection lines， then detecting the monitoring module itself to gradually locate the problem. When using the low-frequency working mode， do not apply it to fast-start and stop units to prevent measurement data from deviating. All signal lines and communication lines should be as far away as possible from strong power cables to reduce the impact of electromagnetic interference on high-precision measurement. This model is equipped with a custom output circuit. During use， it is strictly prohibited to disassemble or modify the hardware structure privately to ensure measurement accuracy and operational stability.
