The Bently Nevada 990-10-XX-01-00 MOD:163930-01 Vibration Transmitter serves as a two-wire, loop-powered device in industrial machinery monitoring applications, delivering a proportional 4 to 20 mA vibration signal directly to machinery control systems. 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), converting the raw signal into appropriate peak-to-peak vibration amplitude engineering units, and transmits this value as an industry-standard 4 to 20 mA output to enable machinery protection alarming and logic within the control system. The 990-10-XX-01-00 MOD:163930-01 features an integrated Proximitor Sensor that requires no external unit, streamlining installation and reducing system complexity.
The 990-10-XX-01-00 MOD:163930-01 provides essential vibration monitoring functions for rotating equipment, and is a critical component of the machinery protection path, directly affecting the proper detection of abnormal operating conditions. One 990-10-XX-01-00 MOD:163930-01 transmitter is required per monitoring point depending on the desired coverage level. The 990-10-XX-01-00 MOD:163930-01 occupies minimal installation space and is compatible with the 3300 NSv proximity probe, allowing transducer installation in small areas with minimal clearance typical of centrifugal air compressors.
For diagnostic applications, the 990-10-XX-01-00 MOD:163930-01 Vibration Transmitter provides non-isolated PROX OUT and COM terminals plus a coaxial connector to deliver a dynamic vibration and gap voltage signal output for condition assessment. In addition to standard 4 to 20 mA signal transmission, the diagnostic capability also supports preventive maintenance. The 990-10-XX-01-00 MOD:163930-01 executes signal verification using the test input pin specified in the transmitter design. Using this method, the Not OK/Signal Defeat circuit continually monitors the health of the proximity probe connection. If the system detects that the probe is no longer providing a valid signal due to a faulty proximity probe or loose connection, it will automatically prevent high outputs or false alarms and maintain system reliability.
The 990-10-XX-01-00 MOD:163930-01 Bently Nevada Vibration Transmitter may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).
