        Features:

        • Serves as the Two-Wire Loop-Powered Interface Between 3300 NSv Proximity Probes and Plant Control Systems
        • Merges Integrated Proximitor Sensing Capability with Continuous 4–20 mA Vibration Signal Output
        • Functions Alongside 3300 NSv Probes and 5 m or 7 m Extension Cable Systems
        The 990-10-XX-01-00 MOD:283278-01 operates as a two-wire loop-powered vibration transmitter, providing a continuous 4–20 mA proportional current signal to machinery control systems monitoring rotating equipment. It continuously accepts input from 3300 NSv eddy current proximity probes and extension cables (available in 5 m or 7 m system lengths), converting vibration peak-to-peak amplitude into a regulated 4–20 mA output for direct integration into PLC, DCS, or other industrial control loops. Standard signal compatibility is maintained across the 4–20 mA loop, and the integrated Proximitor sensor eliminates the requirement for an external proximitor unit in space-constrained OEM installations.

        The 990-10-XX-01-00 MOD:283278-01 provides essential vibration measurement functions for individual machine protection points, and is a critical component of the machinery monitoring path, directly affecting the proper, normal operation of the overall protection system. One 990-10-XX-01-00 transmitter is required per measurement point depending on the desired monitoring coverage.

        For enhanced signal integrity applications, the 990-10-XX-01-00 MOD:165353-01 incorporates an integrated Not OK/Signal Defeat circuit and power-up inhibit circuitry in addition to standard vibration measurement operation. The Not OK configuration performs automatic signal validation, while the power-up inhibit prevents signal errors caused by line voltage transients during startup. The 990-10-XX-01-00 executes signal defeat using the internal circuitry specified in the transmitter design.

        The 990-10-XX-01-00 MOD:283278-01 Bently Nevada Vibration Transmitter may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

        General

        • Manufacturer Bently Nevada
        • Model 990-10-XX-01-00 MOD:283278-01
        • Condition New Original ready stock
        • Product Family 990-50-XX-01-00,990-70-XX-01-00
        Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
        • Centrifugal Air Compressors: Due to its compact architecture and compatibility with 3300 NSv (Narrow Side View) proximity probes, it is the industry benchmark for monitoring tight-clearance compressor shafts.
        • Industrial Rotating Machinery: It provides continuous radial vibration monitoring for everyday plant assets, including industrial fans, blowers, electric motors, and small process pumps.
        • Field-Level Asset Protection: It serves as an ideal solution for skid-mounted machinery where installation space is restricted and dedicated, full-scale rack monitoring systems are cost-prohibitive.
        • Machinery Diagnostics: The device features a dedicated "PROX OUT" dynamic signal terminal. This allows maintenance teams to temporarily attach portable vibration analyzers and capture raw waveform data for troubleshooting without disturbing the active loop.
        • Transmitter Operating Temperature: -35 °C to +85 °C (-31 °F to +185 °F).
        • Transmitter Storage Temperature: -51 °C to +100 °C (-60 °F to +212 °F).
        • Associated Probe Operating Temperature: -35 °C to +177 °C (-31 °F to +350 °F).
        • Relative Humidity Compatibility: Up to 100% condensing. While the potted housing completely isolates internal electronics from ambient moisture, external coaxial connections must be appropriately sleeved or protected to prevent signal degradation. The unit is not rated for fluid submersion.
        • Signal Conversion: The transmitter receives raw eddy-current gap signals from a 3300 NSv proximity probe, processes the peak-to-peak vibration amplitude, and converts it into a proportional 4 to 20 mA DC analog loop current.
        • Automation Integration: This 4-20 mA loop wires directly into standard Programmable Logic Controllers (PLCs), Distributed Control Systems (DCS), or SCADA platforms. All high-vibration alarms, trip logic, and emergency shutdowns are executed at the controller level.
        • "Not OK" Signal Defeat: To protect against false plant trips, the transmitter features an onboard safety circuit. If a probe cable breaks or detaches, the loop current drops below 3.6 mA within 100 microseconds, immediately letting the DCS know the sensor is faulty rather than triggering an emergency machinery shutdown.
        • Loop Validation: The device includes an external Test Input pin under its front label. Maintenance technicians can inject an artificial signal from a portable wave generator into this pin to quickly verify that the entire loop, along with its DCS trip thresholds, is reading accurately.
        Description
        As a benchmark product in the field of industrial asset protection and condition monitoring, the Bently Nevada 990-10-XX-01-00 MOD:283278-01 vibration transmitter, with its accurate signal acquisition and stable performance, has become a core monitoring component for rotating equipment such as centrifugal air compressors, small water pumps, motors, and fans. This transmitter adopts a two-wire loop-powered design, eliminating the need for an additional power module, effectively simplifying on-site installation and wiring, reducing system deployment costs, and also featuring a typical 23mA current-limiting protection function to ensure equipment and personnel safety. 

        In terms of core performance and adaptability, this Bently Nevada 990-10-XX-01-00 MOD:283278-01 is precisely matched with the Bently Nevada 3300 NSv proximity probe and its dedicated extension cable, supporting both 5-meter and 7-meter system length options to flexibly adapt to different field installation distance requirements. For measurement range, it features a full-range configuration of 0-10 mils pp (i.e., 0-250μm pp), coupled with non-interactive external zeroing and range adjustment functions, facilitating quick calibration and debugging by field personnel to ensure measurement accuracy. The 35mm DIN rail clamp design ensures convenient and efficient installation, allowing easy integration into various industrial control cabinets and adaptability to the harsh industrial environments of industries such as metallurgy, petroleum, chemical, and power.

        The Bently Nevada 990-10-XX-01-00 MOD:283278-01 possesses excellent fault response and protection capabilities. Its NOT OK/signal failure function can reduce the signal to below 3.6mA within 100μs in abnormal operating conditions such as probe failure or loose connection. After fault resolution, normal output is quickly restored within 2-3 seconds, effectively preventing control system misjudgments or equipment damage caused by signal abnormalities.
