Bently Nevada 990-04-50-01-CN — Precision Sensing You Can Trust
When you maintain rotating machinery, every vibration sensor is a single point of failure for data quality. If a sensor drifts, the monitor still displays numbers — but those numbers are wrong, and wrong data leads to wrong decisions.
The Bently Nevada 990-04-50-01-CN 2-Wire Vibration Transmitter is a genuine Bently Nevada sensor. Model: 990-04-50-01-CN; Type: 2-Wire Vibration Transmitter; Measurement Range: 0 to 100 µm (peak-to-peak); System Length: 5.0 meters (16.4 feet). We verify every unit on a calibrated test bench: scale factor, linearity, and gap voltage measured against the manufacturer calibration sheet. Units that deviate are not shipped. A printed test report with serial number, test date, and measured values accompanies every order.
Installation matters. For eddy-current probes, the target surface must be clean, smooth, and at least twice the probe tip diameter. Set gap voltage with a meter before tightening. Verify output after installation. If replacing a failed sensor, order a spare — the cost is trivial compared to one unplanned outage. 12-month warranty. Ships within 24 hours from Shenzhen.
