The 990-10-XX-01-00 163930-01 is a non-contact vibration transmitter that directly converts mechanical shaft vibration acquired by eddy current proximity probes into an industry-standard 4-20mA analog current signal. It transmits data directly to PLC or DCS systems, completely eliminating the need for an additional proximity sensor (Proximitor) or monitor module.
Non-interacting zero and span potentiometers under the Transmitter label supports loop adjustment
Test Input pin for quick verification of loop signal output, using a function generator as the input
Choice of DIN-rail clips or bulkhead mounting screws as standard options simplifies mounting
The 990 Vibration Transmitter is intended primarily for the original equipment manufacturers (OEMs) of centrifugal air compressors or small pumps, motors, or fans who prefer to provide a simple 4 to 20 mA proportional vibration signal as the input to their machinery control system. The transmitter is a two-wire, loop-powered device that accepts input from our 3300 NSv proximity probe and its matching extension cable (available in 5 m and 7 m system length options).
The transmitter conditions the signal into appropriate peak to-peak vibration amplitude engineering units, and provides this value as a proportional 4 to 20 mA industry-standard signal as the input to the control system where machinery protection alarming and logic occurs.
The 990-10-XX-01-00 transmitter housing is enclosed in a durable, compact package suitable for standard 35 mm DIN rail mounting within local field enclosures. It integrates the 163930-01 internal main circuit board, which establishes high electrical isolation barriers to shield the connected control automation loop from environmental field noise. The hardware layout features dedicated coaxial PROX terminals on the front panel, providing unconditioned dynamic voltage outputs for direct link-up with portable machinery diagnostic analyzers.

When operating the 990-10-XX-01-00 (including the 163930-01 main board), strictly match it with 3300 NSv probes and appropriate cables, and ensure the static gap voltage is verified via front terminals within the -9 Vdc to -10 Vdc linear range. As a loop-powered device, it requires a positive +12 Vdc to +36 Vdc supply, not a negative voltage. Always ensure reliable enclosure grounding through the DIN rail clip, and strictly follow "-01" Intrinsic Safety compliance regulations in hazardous areas.
990-10-XX-01-00 supports standard 35 mm DIN rail mounting and features a dedicated coaxial PROX terminal on the front panel to provide unconditioned dynamic voltage signals for external failure analysis. The "-01" suffix indicates official intrinsic safety hazardous area certifications from ATEX, IECEx, and CSA. Operating as a factory line-replaceable unit (LRU), this hardware allows for calibration-free, rapid swap-outs in heavy industrial field environments with high electromagnetic noise, serving as a highly isolated machinery protection solution for OEM equipment manufacturers.
