Quick Detail

Description

The 330902-05-30-10-02-05 3300 NSv Proximity Probe is a compact, high-precision transducer designed for industrial automation and condition monitoring in machines with tight installation requirements. Engineered for use with centrifugal air compressors, refrigeration compressors, and process gas compressors, this probe enables reliable radial vibration and axial position measurements even in restricted or side-view-limited spaces. The probe features a 1/4-28 UNF threaded stainless steel case and a durable PPS tip, providing excellent chemical and mechanical resistance while operating across a wide temperature range of -52°C to +177°C (-62°F to +351°F). Its standard 1.0-meter (39 in) cable with miniature ClickLoc coaxial connector ensures secure, high-fidelity signal transmission, compatible with NSv extension cables and Proximitor sensors. The 3300 NSv Proximity Probe supports a linear measurement range of 1.5 mm (60 mils) with a recommended gap of 1.0 mm (40 mils) and output resistance of 50 Ω, maintaining supply sensitivity under 2 mV per volt. Patented TipLoc and CableLoc designs provide robust probe-tip bonding and secure cable attachment up to 220 N (50 lb) pull strength. Mechanically and electrically compatible with legacy 3300 RAM and 3000/7000-series systems, the probe allows seamless system upgrades while meeting API 670 standards for precision and reliability in industrial automation.

Applications

Radial Vibration Monitoring

Measures shaft vibrations on small-diameter shafts (<51 mm / 2 in) with high precision, providing real-time data for predictive maintenance and reducing unplanned downtime.

Axial (Thrust) Position Measurement

Monitors axial displacement in fluid-film bearing machines, ensuring accurate alignment and preventing over-travel or mechanical interference.

Tachometer and Zero-Speed Detection

Provides precise rotational speed and zero-speed signals for machinery control, supporting automation and safety systems with stable output under ±2 mV per volt supply variation.

Small Target Monitoring in Restricted Spaces

Designed for side-view, rear-view, and counterbore-restricted installations, enabling measurements on flat targets smaller than 15 mm (0.6 in) without compromising accuracy.

Process Compressor and Harsh Environment Applications

Chemical-resistant PPS tip and stainless steel housing ensure reliable performance in oil-lubricated or chemically aggressive environments, enhancing long-term reliability.

Specifications
