Product Description

The Bently Nevada 1034549-21 is a precision Proximitor® sensor from the 3300 XL 8mm series, engineered for accurate measurement of vibration and shaft position in industrial rotating equipment. It converts the gap between the probe and a target shaft into a linear voltage signal, providing critical input for machinery protection, condition monitoring, and predictive maintenance systems.

Key Features

High-Precision Sensing
The sensor’s exceptional linearity ensures that voltage output directly corresponds to shaft displacement or vibration. With a typical linear range of 2.0 mm (80 mils) and standard incremental scale factor of 7.87 V/mm (200 mV/mil), it delivers reliable readings across its entire operating range.

Robust Environmental Performance
Designed for harsh industrial conditions, the 1034549-21 performs consistently across temperatures from -51°C to +100°C (-60°F to +212°F). Its rugged design tolerates vibration, shock, and EMI typical in power plants, refineries, and manufacturing facilities.

Versatile Integration
Compatible with the 3300 XL 8mm Proximitor system, it supports standard probes, extension cables, and mounting hardware. Tight tolerances allow replacement or swap of components without requiring recalibration. DIN rail or panel mounting options simplify installation.

Reliable Electrical Performance
Operates on a negative voltage supply (e.g., -24 Vdc) with low output impedance to maintain signal integrity over long cable runs. It provides real-time processing for condition monitoring, seismic detection, and alarm generation.

FAQ

Q: What is the purpose of the -21 suffix?
A: The "-21" typically indicates specific approvals or mounting configurations. Verify agency requirements before installation.

Q: Can the sensor be replaced without recalibration?
A: Yes. Tight mechanical tolerances allow probe, cable, and sensor swaps without adjustment.

Q: What is the maximum frequency it can measure?
A: Up to 10 kHz, suitable for high-speed machinery vibrations.

Q: How is the sensor mounted?
A: Supports DIN rail or panel mounting, depending on installation preferences.

Q: What industrial conditions can it withstand?
A: It operates reliably in extreme temperatures (-51°C to +100°C) and is resistant to EMI and vibration typical in heavy industry.
