🔬 Measurement Precision

This proximitor delivers laboratory-grade accuracy in industrial environments. Its low-noise front-end circuitry resolves shaft movements down to 0.1 mil (2.5 μm), enabling early detection of bearing wear, rotor unbalance, and alignment issues before they escalate into failures.

The wide frequency response captures both slow-roll data at startup (sub-1 Hz) and high-frequency bearing defects (up to 10 kHz) in a single measurement channel—eliminating the need for multiple sensor types and simplifying system architecture.

🛡️ Industrial Hardening

✓ EMI/RFI Immunity: Operates reliably near VFDs, welders, and high-voltage equipment
✓ Transient Protection: Survives voltage spikes and ground faults without damage
✓ Thermal Stability: Maintains calibration across full temperature range
✓ Conformal Coating: Protects circuitry from moisture, dust, and chemicals
✓ Vibration Resistant: Tested to 5g continuous, 10g shock

🎯 Target Applications

Steam Turbine Monitoring: Track journal bearing vibration and thrust position in power generation units where reliability directly impacts grid stability and revenue generation.

Gas Compressor Protection: Monitor shaft dynamics in pipeline compressors handling natural gas—where unplanned shutdowns disrupt supply contracts and incur substantial penalties.

Centrifugal Pump Surveillance: Detect cavitation, impeller damage, and seal wear in critical process pumps before catastrophic failure floods facilities or releases hazardous materials.

💼 Installation Flexibility

The 3300/20-03-01-02-01-00 mounts via DIN rail or panel brackets, adapting to diverse cabinet configurations. Its compact form factor conserves valuable panel space in crowded control rooms. Terminal blocks accept 14-22 AWG wire for robust field connections that withstand vibration and thermal cycling.

Buffered outputs drive multiple loads simultaneously—feed one output to a protection relay and another to a DCS trending system without signal degradation or impedance matching concerns. This eliminates the need for external signal splitters and their associated failure modes.

🔧 System Ecosystem

Pairs with any Bently Nevada 8mm proximity probe and standard extension cables. Integrates seamlessly with 3500 rack monitoring systems, standalone trip modules, and third-party PLCs/DCS platforms via industry-standard voltage interfaces. Configuration is straightforward—no proprietary software required for basic installations.
