Quick Detail

Description

The 330902-05-20-10-02-05 3300 NSv Proximity Probe is a compact, high-precision transducer engineered for industrial automation and condition monitoring systems in tight or restricted installation environments. Designed for centrifugal air compressors, refrigeration compressors, process gas compressors, and other fluid-film bearing machines, this NSv probe provides accurate measurement of radial vibration, axial displacement, and phase reference (Keyphasor) signals. Its 1/4-28 UNF threaded AISI 304 stainless steel case and durable PPS probe tip provide excellent chemical and mechanical resistance, operating reliably across -52°C to +177°C (-62°F to +351°F). The probe includes a standard 1.0-meter (39 in) cable with a miniature ClickLoc coaxial connector, ensuring secure, high-fidelity signal transmission compatible with NSv extension cables and Proximitor sensors. The linear measurement range of 1.5 mm (60 mils) with a recommended gap of 1.0 mm (40 mils) delivers precise readings, while the 50 Ω output resistance and supply sensitivity under 2 mV per volt provide consistent data for industrial automation and condition monitoring. Patented TipLoc and CableLoc designs ensure robust probe-tip bonding and secure cable attachment with 220 N (50 lb) pull strength, preventing disconnection in vibration-prone environments. Compatible with legacy 3300 RAM and 3000/7000-series systems, this probe supports seamless upgrades while meeting API 670 standards for accuracy and reliability.

Applications

Radial Vibration Monitoring

Captures high-precision radial vibration signals from shafts smaller than 51 mm (2 in), enabling early fault detection in fluid-film bearing machinery.

Axial (Thrust) Position Measurement

Monitors axial movement in confined spaces, providing ±0.05 mm measurement accuracy to prevent mechanical interference or misalignment.

Tachometer and Zero-Speed Detection

Generates accurate rotational speed and zero-speed signals, supporting automation and safety systems with stable output under high-frequency operating conditions.

Small Target and Restricted Space Measurement

Designed for side-view, rear-view, or counterbore-restricted installations, allowing measurements on flat targets smaller than 15 mm (0.6 in) without loss of accuracy.

Process Gas Compressor Applications

High chemical resistance and durable stainless steel housing ensure reliable performance in aggressive process environments, including oil or chemical exposure.

Specifications

Competitive Advantage

Compact Reverse-Mount Design

Enables installation in tight or side-view-limited spaces without major modifications, improving automation system flexibility.

Wide Operating Temperature Range

Reliable performance from -52°C to +177°C ensures consistent measurements in extreme industrial environments.

Robust Mechanical Reliability

TipLoc and CableLoc designs deliver strong probe-tip bonding and 220 N (50 lb) pull strength for secure cable attachment, reducing maintenance downtime.

Legacy System Compatibility

Mechanically and electrically interchangeable with 3300 RAM and 3000/7000-series probes and extension cables, simplifying system upgrades and reducing costs.

High-Fidelity Signal Output

Linear range of 1.5 mm with 50 Ω output resistance and <2 mV per volt sensitivity ensures precise radial, axial, and Keyphasor measurements for predictive maintenance and automation control.
