The 990-10-XX-01-00 (Internal SKU/Part Number: 283278-01) is an industrial, loop-powered 990 Vibration Transmitter engineered by Bently Nevada (a Baker Hughes business). This specialized device provides continuous machinery condition monitoring and asset protection by interfacing field transducers directly with plant automation systems. It integrates the high-frequency signal conditioning electronics of a proximity sensor and an analog transmitter into a single, compact polycarbonate housing. The unit accepts inputs from a non-contacting 3300 XL 8mm eddy-current proximity probe and extension cable system, converting raw shaft micro-gap variations into a linear, proportional 4 to 20 mA analog current loop output. This configuration enables plant operators to route critical radial vibration data straight to Distributed Control Systems (DCS) or Programmable Logic Controllers (PLC) without the added infrastructure of a separate, rack-based monitor chassis.
This exact hardware configuration features an expanded factory-calibrated full-scale measurement scale of 0-10 mils pp (0-250 um pp), designed for machines with larger expected rotor vibration amplitudes. The unit is equipped with integrated 35 mm DIN rail clips for rapid, toolless snap-on installation into local marshalling junction boxes. The agency option is designated as -00, which represents the standard, non-hazardous area base model for general-purpose plant zones. The internal tracking number 283278-01 represents the modern OEM manufacturing assembly designation, incorporating high-stability surface-mount components and enhanced RFI/EMI noise suppression filters over legacy iterations while maintaining identical physical and electrical drop-in backward compatibility.
