Product Overview
The Bently Nevada P3403893-0416 is a high-precision 990-series vibration transmitter for continuous machinery protection on smaller or less critical rotating equipment.
It integrates a Proximitor sensor and signal conditioner into a compact unit, providing a 4-20 mA output compatible with PLC or DCS systems. The rugged housing and simplified mounting make it ideal for localized monitoring where a full 3500 rack is not cost-effective.

FAQ
Q1: What probe is compatible with this transmitter?
A1: Calibrated for Bently Nevada 3300 NSv proximity probes. Ensure probe and extension cable lengths match the calibration (typically 5 m or 7 m).
Q2: Can I adjust the 4-20 mA range in the field?
A2: Minor adjustments are possible, but the transmitter is factory-calibrated. For best accuracy, order the part number matching the desired engineering units.
Q3: Is this transmitter a replacement for a full 3500/42M monitor?
A3: No. It provides continuous data but lacks logic voting and high-speed relay capabilities of a 3500 rack. Use for monitoring/trending, but rely on 3500 series for critical trips.
Q4: How do I verify the health of the loop?
A4: Check the 4-20 mA loop voltage or the OK LED. A steady LED indicates linear range operation and functional internal circuitry.
