Quick Detail

Description

The 330902-00-10-10-01-00 3300 NSv Proximity Probe is a precision eddy-current transducer designed for high-performance vibration and position measurement in compact and constrained industrial machinery environments. Specifically engineered for centrifugal air compressors, refrigeration compressors, and process gas compressors, the 3300 NSv provides reliable radial and axial monitoring even in tight installation spaces where standard 3300 XL 5 and 8 mm probes cannot fit. With a linear range of 1.5 mm (60 mils), recommended gap of 1.0 mm, output resistance of 50 Ω, and supply sensitivity below 2 mV per input volt, the probe delivers accurate non-contacting measurements under extreme operating conditions from −52°C to +177°C. Its AISI 304 stainless steel case and PPS probe tip provide chemical and thermal resistance suitable for aggressive process environments. Mechanically compatible with previous 3300 RAM systems, the 3300 NSv probe supports upgrades without requiring new cabling, while patented TipLoc and CableLoc technologies provide robust probe-cable bonding with 220 N pull strength. Optional connector protectors prevent ingress of liquids, ensuring stable electrical performance in harsh automation systems. This probe is ideal for fluid-film bearing machinery, small shaft diameters (<51 mm), and axial position monitoring of flat targets smaller than 15 mm, making it a key component in predictive maintenance, condition monitoring, and machine protection systems.

Applications

Application 1
Radial Vibration Measurement
Ideal for shafts smaller than 51 mm, the probe accurately captures radial vibration data on centrifugal compressors with rotational speeds up to 50,000 RPM, allowing precise imbalance detection and machinery diagnostics.

Application 2
Axial (Thrust) Position Monitoring
Used for thrust collar displacement measurement on fluid-film bearings; the 1.5 mm linear range ensures accurate axial position tracking to detect misalignment or mechanical wear in high-speed machinery.

Application 3
Tachometer and Zero-Speed Measurement
Provides reliable speed reference and zero-speed detection for compressors and turbines, supporting safety interlocks and speed-based control logic with high temporal resolution.

Application 4
Keyphasor Phase Reference Signal
Delivers high-fidelity Keyphasor signals for phase angle monitoring and synchronous vibration analysis in rotating equipment, enhancing condition monitoring and predictive maintenance efficiency.

Application 5
Process Gas Compressor Monitoring
With enhanced chemical resistance and sideview probe characteristics, the NSv probe measures both axial and radial positions in tight compressor casings, enabling accurate operational monitoring in harsh process environments.
