The Bently Nevada Bently Nevada 990-04-70-01-00 vibration transmitter is engineered for OEM centrifugal compressors, industrial pumps, motors, and rotating machinery requiring dependable 4–20 mA vibration monitoring. Designed with integrated signal conditioning technology, the transmitter converts dynamic shaft vibration data into a stable industrial output signal for PLC and machinery protection systems.
Built for compatibility with 3300 NSv proximity probes, 990-04-70-01-00 supports compact installations where mounting space is limited. Its rugged encapsulated construction offers reliable performance in humid industrial environments, including compressor skids, power units, and process automation systems.
Unlike conventional monitoring devices, the 990 Series combines simplified installation, DIN-rail mounting flexibility, and diagnostic signal access through PROX OUT connections. The transmitter also features NOT OK protection logic, external zero/span adjustment, and high-frequency response for accurate vibration trending in critical machinery applications.
