The Bently Nevada 990-04-50-01-00 is a loop-powered 990 series vibration transmitter. It provides a 4-20 mA output for centrifugal machinery protection and works with 3300 XL 8mm proximity probes.
The Bently Nevada 990-04-50-01-00 serves as a self-contained vibration transmitter for industrial machinery. This device integrates the functions of a Proximitor sensor into a compact unit. It outputs a standard 4 to 20 mA signal proportional to vibration levels. Consequently, operators can connect it directly to PLCs or DCS systems. This eliminates the need for specialized monitoring racks in many applications.
The 990-04-50-01-00 converts eddy current probe signals into a linear current loop. It monitors shaft vibration with high precision and excellent frequency response. Because the unit is loop-powered, it simplifies field wiring significantly. The transmitter also provides a separate buffered output signal. This allows technicians to perform detailed diagnostics using portable vibration analyzers.
Engineers typically deploy this transmitter on essential but less critical balance-of-plant equipment. It excels at monitoring centrifugal pumps, fans, and small cooling tower motors. Since the device is ruggedly built, it withstands high humidity and temperature fluctuations. It represents an ideal solution for facilities moving toward decentralized condition monitoring.
The 990-04-50-01-00 supports easier system integration than traditional rack-based monitors. Its DIN rail compatibility ensures fast installation within existing control cabinets. Moreover, the unit provides a “Not OK” signal via the current loop. This feature immediately alerts the control system if a probe failure occurs. This proactive diagnostic capability ensures the integrity of your machinery protection system.
This transmitter features a specific configuration tailored for standard industrial interfaces.
