It adopts a 19-inch standard modular frame structure and can be installed in the dedicated cabinet of the 3300 series. The product is designed with a small measurement range and high precision, and is equipped with industry-specific certifications and safety configurations, featuring strong anti-interference ability and stable operation. It is suitable for high-demanding industrial units in power, petrochemical, and metallurgy industries, providing reliable protection for equipment fault early warning, operation control, and safety interlock.

II. Basic Information

This product is manufactured by Bentley Nevada and belongs to the 3300 industrial condition monitoring series. Its model is 3300/16-02-01-00-01-01-01. The equipment type is a dual-channel radial vibration and shaft clearance integrated monitor. Its core functions include dual-channel vibration amplitude measurement, gap voltage collection, calculation of the average position of the shaft, relay alarm output, hardware self-diagnosis, remote parameter configuration, and data monitoring. The product is compatible with 3300 XL, 7200 series eddy current probes and their accompanying preamplifiers. The standard probe sensitivity is 200mV/mil, and it is suitable for mainstream sensing equipment in the field. The entire machine is installed in a standard frame structure and can be directly embedded in the monitoring cabinet of the same series. The product has passed CE electromagnetic compatibility certification and has industry-specific usage certifications and built-in safety barriers, enabling long-term continuous operation in industrial sites with high dust content, complex electromagnetic environments, and harsh working conditions.

III. Functions and Positioning

The module is equipped with two completely isolated independent measurement channels, and 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 device, or separately monitor two different rotating devices. The two sets of data are independently calculated, and the alarm logic is independent. The equipment continuously collects the gap voltage between the shaft and the bearing and converts it to the average operating position of the shaft, achieving dual monitoring of vibration and shaft system position. The small measurement range design has higher monitoring sensitivity and can capture small changes in equipment conditions, meeting the monitoring requirements of precision units.

The equipment is equipped with a warning and danger two-level alarm mechanism. The alarm threshold and alarm delay for each channel can be flexibly set through the local panel or the upper-level monitoring software. When the monitoring parameters exceed the preset limit, the corresponding indicator light on the panel lights up, and the relay outputs 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 and dual-channel bypass functions. During sensor calibration, line maintenance, and equipment maintenance, the alarm output can be temporarily shielded without affecting the normal operation of other system functions, ensuring the continuous operation of the monitoring system.

The module is equipped with a complete fault self-diagnosis circuit, which can detect sensor breakage, line short circuit, abnormal input signals, and hardware faults of the module itself. When an abnormality occurs, the operation indicator light goes out, facilitating the rapid troubleshooting by maintenance personnel. The module is equipped with a sensor signal buffer output interface, which can be externally connected to oscilloscopes, data acquisition instruments, etc., for on-site signal calibration, equipment debugging, and in-depth analysis of faults. This model does not have analog output. It has industry-specific certification, an internal safety barrier, and is paired with an exclusive hardware version, suitable for high-risk and compliant industrial scenarios.

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 transmission attenuation. 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 data distortion.

The full-scale range of this model for vibration measurement is 0 to 125 micrometers peak-to-peak, with a measurement accuracy of ±1% of the full scale. The gap voltage measurement range 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 built-in, and the maximum power consumption of the entire machine does not exceed 5W. The power supply voltage can fluctuate within ±10% of the rated value and still operate stably.

The alarms are divided into two levels: warning and danger. Each channel is independently configured. The rated parameters of the relay contacts are 24V DC and 1A, supporting on-off mode switching. The alarm delay can be programmed within 0 to 10 seconds, effectively filtering instantaneous interference signals and reducing the probability of false alarms.

In terms of environmental parameters, the working temperature range is -40℃ to +70℃, the storage temperature range is -52℃ to +105℃, and the applicable relative humidity is 5% to 95%. The operating environment requires no condensation. The front of the equipment is equipped with an LED digital display, which can switch to view the vibration values and gap voltages of the two channels, and also has independent status indicator lights for operation, bypass, warning, and danger. The module integrates an RS-485 communication interface, which can be connected to the upper system to achieve remote parameter configuration, data reading, and alarm monitoring. The module has an internal safety barrier, which can meet the usage conditions of high-risk situations.

VII. Installation and Maintenance Key Points

The equipment is installed in a 19-inch standard rack. During assembly, sufficient space should be reserved between the modules to ensure ventilation and heat dissipation, avoiding temperature accumulation that affects measurement accuracy and operational stability. This module integrates a safety barrier and is a high-precision model. During wiring, strictly distinguish between A and B signal channels, the positive and negative poles of the power supply, relay terminals, and communication lines. Follow the marking specifications for wiring and strictly prohibit incorrect or reverse connections. It is recommended to perform channel accuracy calibration using original factory tools every six months. After calibration, lock the parameters to prevent unauthorized personnel from随意 modifying them.

During daily maintenance， keep the cabinet and module panel clean. Avoid allowing dust and oil to enter the equipment interior. Regularly inspect all wiring terminals and promptly tighten loose lines to prevent poor contact and abnormal signals. When the equipment malfunctions or has abnormal alarms， conduct maintenance in the following order： first check the sensors and lines， then test the module body. When using the low-frequency working mode， do not use it for rapid start-stop of the unit to avoid data distortion. Keep the communication lines away from strong power cables to reduce electromagnetic interference. This model comes with special certification and safety barriers. It is strictly prohibited to disassemble， modify the hardware or internal circuits privately to ensure the equipment operates in compliance and safely.
