Features:
- Interface Between the 3300 NSv Proximity Probe and Machinery Control System
- Combines Signal Conditioning with Proportional 4 to 20 mA Vibration Output
- Operates in Conjunction with Centrifugal Air Compressors, Small Pumps, Motors, and Fans
The Bently Nevada 990-08-50-01-05 Vibration Transmitter operates as a two-wire, loop-powered device designed primarily for original equipment manufacturers (OEMs) of centrifugal air compressors or small pumps, motors, or fans. It continuously accepts input from the 3300 NSv proximity probe and its matching extension cable (available in 5 m and 7 m system length options), 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. Seamless integration with existing control systems is standard with the 990-08-50-01-05, however using the Test Input pin allows quick verification of loop signal output using a function generator as the input.
The 990-08-50-01-05 provides essential vibration monitoring functions common to rotating machinery, and is a critical component of the protection path, directly affecting the proper, normal operation of the overall machinery control system. One 990-08-50-01-05 transmitter is required per monitoring point depending on the desired coverage level. The 990-08-50-01-05 offers a choice of DIN-rail clips or bulkhead mounting screws as standard options and is always suitable for installation in small areas with minimal clearance, typical of centrifugal air compressors.
For high humidity environments, the 990-08-50-01-05 Vibration Transmitter requires no additional enclosure as it features potted construction for environments up to 100% condensing. In addition to standard signal output operation, the diagnostic configuration also performs dynamic vibration and gap voltage signal output. The 990-08-50-01-05 diagnostic system executes output using the Non-isolated PROX OUT and COM terminals plus a coaxial connector specified in the transmitter options.
The 990-08-50-01-05 Bently Nevada Vibration Transmitter may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).
