Bently Nevada 140734-03 — Why Calibration and Installation Both Matter
If you maintain rotating machinery, you already know that vibration sensors are the foundation of your condition monitoring program. Every alarm trip, every maintenance work order, every shutdown decision starts with the signal from this device. When a sensor drifts out of calibration — which happens gradually over years of thermal cycling and vibration — the monitor rack still displays numbers. The operators still make decisions. But those decisions are based on wrong data.
The Bently Nevada 3500/44M 140734-03 Aeroderivitive Gt Vibration Monitor is a genuine Bently Nevada sensor. Input Signals:: Accepts signals from four Velocity Transducers; Dimensions:: 241.3 mm x 24.4 mm x 241.8 mm; Weight:: 0.91 kg (2.0 lbs); Power Consumption:: 7.7 watts, typical. Not an aftermarket equivalent manufactured to looser tolerances — a genuine Bently Nevada unit with the manufacturer calibration certificate and holographic label intact. We verify every unit on a calibrated test bench before shipping: scale factor, linearity, and gap voltage measured against the manufacturer specification. Units that deviate from specification are not shipped. A printed test report accompanies every order.
Installation best practices: For eddy-current probes, the target surface must be clean, smooth, conductive, and at least twice the probe tip diameter. Use a calibrated gap meter to set the correct gap voltage before tightening the lock nut. Verify the output voltage at the proximitor after installation — before returning the machine to service. A probe installed with incorrect gap reports vibration amplitudes that are either dangerously low (missed faults) or falsely high (unnecessary trips). If you are replacing a failed sensor, order a spare at the same time. The cost of one spare sensor is negligible compared to one unplanned outage on a critical machine.
