Quick Detail

Description

The 330905-00-25-05-12-CN 3300 NSv Proximity Probe is engineered for automated monitoring of centrifugal air compressors, refrigeration compressors, and process gas compressors with tight installation spaces. Featuring a 250 mm overall case, 0.5 m FluidLoc cable, and M10×1 thread, the 330905-00-25-05-12-CN 3300 NSv Proximity Probe supports precise radial vibration measurement on shafts <51 mm and axial position monitoring on targets <15 mm. Its PPS probe tip and AISI 304 stainless steel case operate between −52°C and +177°C, while the 1.5 mm linear range and 1.0 mm recommended gap enable high-resolution readings. Output resistance 50 Ω and supply sensitivity <2 mV/V ensure accurate signal transmission to DCS and PLC systems. ClickLoc connectors with CableLoc design maintain secure connections, and connector protectors reduce liquid ingress. The 330905-00-25-05-12-CN 3300 NSv Proximity Probe integrates into existing 3300 RAM systems, providing upgrades with minimal wiring changes while enhancing automation signal quality.

Applications

Radial Vibration Measurement on Small Shafts
The 330905-00-25-05-12-CN 3300 NSv Proximity Probe accurately measures radial vibration on shafts smaller than 51 mm (2 in) using its 1.5 mm linear range and 7.87 V/mm average scale factor. The recommended gap of 1.0 mm ensures precise signal detection even in compact centrifugal air compressors or process gas compressors. Its output resistance of 50 Ω and supply sensitivity of <2 mV per volt maintain signal integrity in varying electrical environments.

Axial (Thrust) Position Measurement
With a probe tip material of PPS and AISI 304 stainless steel case, the 330905-00-25-05-12-CN 3300 NSv Proximity Probe resists chemical corrosion while providing high-resolution axial position readings on flat targets smaller than 15 mm (0.6 in). The maximum thread engagement of 15 mm allows secure mounting for reverse-mount applications, and the Miniature coaxial ClickLoc connector with FluidLoc cable ensures minimal signal loss over its 0.5 m (20 in) cable length.

Tachometer and Zero-Speed Detection
For speed measurement, the 330905-00-25-05-12-CN 3300 NSv Proximity Probe converts eddy-current signals into reliable voltage output with low sensitivity to supply variations. The combination of linear range 1.5 mm and output resistance 50 Ω ensures accurate zero-speed detection on small diameter shafts, making it suitable for tight installations in refrigeration compressors or side-view limited machinery.

Phase Reference (Keyphasor) Signal Generation
The 330905-00-25-05-12-CN 3300 NSv Proximity Probe delivers precise Keyphasor signals due to its robust TipLoc molded tip and ClickLoc connector system, which minimizes electrical noise. Its field wiring range of 0.2–1.5 mm² ensures compatibility with standard instrumentation, allowing phase synchronization for rotordynamic monitoring in complex industrial systems.

Specifications

Competitive Advantage

Compact Design for Restricted Installations
The 330905-00-25-05-12-CN 3300 NSv Proximity Probe has a case length of 250 mm with unthreaded length option 0 mm, making it ideal for side-view, counter bore, or rear-view limited applications. Its M10X1 probe thread and maximum engagement of 15 mm allow versatile mounting while maintaining linear measurement performance.

Enhanced Chemical and Temperature Resistance
Featuring PPS probe tip and AISI 304 SST case, the 330905-00-25-05-12-CN 3300 NSv Proximity Probe operates reliably in temperature ranges from -52°C to +177°C (-62°F to +351°F), suitable for process compressors exposed to high heat or corrosive media. This chemical resistance surpasses previous 3300 RAM probes, extending operational life in harsh environments.

Seamless Upgrade Path with Legacy Compatibility
The 330905-00-25-05-12-CN 3300 NSv Proximity Probe is mechanically and electrically compatible with 3300 RAM probes, supporting upgrades without replacing extension cables or monitoring systems. Its linear range 1.5 mm and average scale factor 7.87 V/mm maintain consistent performance with older systems, reducing installation time and engineering costs.

Robust Connector and Cable Engineering
The 330905-00-25-05-12-CN 3300 NSv Proximity Probe features Miniature coaxial ClickLoc connectors and CableLoc design providing 220 N (50 lb) pull strength, preventing disconnection during operation. Gold-plated contacts reduce electrical resistance, while the 0.5 m FluidLoc cable ensures secure signal transmission even under vibration or high-temperature conditions.

Optimized Side-View and Small Target Measurement
The 330905-00-25-05-12-CN 3300 NSv Proximity Probe’s 1.5 mm linear range and 7.87 V/mm scale factor provide superior measurement accuracy on small shafts and targets. Compared to 3000-series 190 probes, it maintains reliable gapping at 1.0 mm recommended distance, enabling precise radial and axial vibration detection in tight machine assemblies.
