Bently Nevada, a benchmark brand in the field of global industrial asset protection and condition monitoring, launched the core product of the 3500/42M series — the 128229-01 four-channel near/earthquake IO monitoring module. With its multi-parameter integrated monitoring, extreme environment adaptability, and modular compatibility advantages, it provides a full-cycle safety protection solution for rotating machinery in such as petrochemicals, power, and manufacturing, redefining the accuracy and reliability of industrial equipment condition monitoring.

The 128229-01, as the flagship-level monitoring module of the 3500 series achieves multi-dimensional parameter synchronous monitoring with its four-channel integrated design, which can receive input signals from eddy current displacement sensors, velocity/acceleration sensors, covering core functions such as radial vibration, axial displacement, differential expansion, shaft eccentricity, and rolling bearing vibration. The product is equipped with a high-sensitivity signal processing chip with a measurement of ±0.5% FS, which can be improved to ±0.1% under certain operating conditions, and a frequency response range of 10Hz-10, which can accurately capture the micron-level vibration changes and position deviations of the equipment, providing data support for fault prediction.

In terms of signal processing and output, the supports 4-20mA analog output, RS-485 digital communication, and Ethernet interface, with a maximum sampling rate of up to 256kHz, can transmit processed signals to the DCS system or 3500 frame configuration software in real time. Users can independently program each channel through software, flexibly configure alarm thresholds dangerous set values, and achieve a closed-loop response of "monitoring - analysis - alarm". Its unique channel paired configuration function allows channels 1-2 and 34 to perform different monitoring tasks respectively, adapting to the multi-parameter monitoring needs of complex equipment.

To meet the harsh requirements of industrial scenarios, the 128229-01 is made of aluminum alloy and has an IP65/IP6 protection level (depending on the configuration), covering a working temperature range of -40℃ to  85℃ and a storage temperature that can withstand -40℃ to85℃, and it can operate stably in harsh industrial environments with high temperature, high humidity, and heavy dust. The product fully complies with the API 670 standard of the American Petroleum Institute and has passed the ATEX, CSA explosion-proof certification, and has strong electromagnetic interference protection capabilities, which can be applied to explosionproof areas in petrochemical industries and high-voltage scenarios in the power industry without special modification.
