The 990-05-XX-03-CN (Internal Part Number: 104M1359-01) is an industrial, loop-powered 990 Vibration Transmitter engineered by Bently Nevada (a Baker Hughes business) to deliver continuous machinery condition tracking directly to plant control systems. This integrated field unit combines the signal-conditioning electronics of a proximity sensor and a transmitter into a single, space-saving package. It accepts inputs from a non-contacting 3300 XL 8mm eddy-current proximity probe and extension cable system, converting dynamic shaft micro-gap variations into a linear 4 to 20 mA analog current loop. This direct interface allows plant operators to route critical vibration data straight into Programmable Logic Controllers (PLC) or Distributed Control Systems (DCS) without the need for a separate rack-based monitoring monitor.
The exact hardware configuration 990-05-XX-03-CN features a factory-calibrated full-scale measurement scale of 0-5 mils pp (0-125 um pp), optimized for monitoring radial shaft vibration amplitudes. It is equipped with a Bulkhead Coaxial Connector Mounting Option, ensuring a high-integrity mechanical and electrical anchor through junction box enclosures or field bulkheads. Certified with the CN agency approval designation, this module complies with global safety frameworks, including ATEX/IECEx and local Chinese NEPSI hazardous area regulations. The part number 104M1359-01 represents the modern OEM manufacturing assembly designation, incorporating upgraded high-stability surface-mount components and improved RFI/EMI shielding over older product iterations while maintaining identical physical and electrical drop-in backward compatibility.
