-- 2-wire, loop-powered vibration transmitter compatible with 3300 NSv proximity probes
-- Combines proximity sensing and signal transmission in a single module
-- Provides 4-20 mA output proportional to radial vibration for PLC or DCS input
-- Includes Prox Out BNC connector for portable diagnostic equipment
-- "Not OK" circuit drives output low if sensor or cable faults occur
-- Direct link to control systems without a separate monitor rack
-- Compact DIN rail mounting and standard industrial design
The Bently Nevada 990-04-50-01-00 is a loop-powered 2-wire vibration transmitter designed for the 3300 NSv proximity probe system. It integrates a proximity sensor and transmitter into a single compact module, providing a 4-20 mA DC signal proportional to radial vibration. This allows direct connection to PLCs or DCS analog input channels for real-time monitoring, diagnostics, and machinery protection. The module includes a Prox Out port for portable diagnostic measurements, a "Not OK" circuit that prevents false readings during probe or cable faults, and easy DIN rail mounting. With a frequency response of 5 Hz to 6,000 Hz, ±1.5% loop accuracy, and robust industrial operating conditions, this module is ideal for turbines, compressors, pumps, and other critical rotating equipment. It ensures reliable vibration measurement, supporting predictive maintenance and machinery protection programs across power generation, petrochemical, and industrial facilities.
