Quick Detail

Description

330905-00-09-05-02-CN 3300 NSv Proximity Probe is an eddy-current displacement sensor used in automated machine protection and condition monitoring. The 330905-00-09-05-02-CN features a 90 mm case with M10×1 thread and 0.5 m miniature coaxial ClickLoc cable for direct connection to monitoring modules. Linear range is 1.5 mm with a recommended 1.0 mm gap and 50 Ω output, enabling accurate shaft displacement input to PLC and DCS systems.

With an operating temperature of −52 °C to +177 °C, 330905-00-09-05-02-CN can be installed on centrifugal compressors and process gas equipment. The PPS tip and AISI 304 stainless housing of 330905-00-09-05-02-CN detect radial vibration, axial thrust position, Keyphasor phase pulses, and zero-speed signals on shafts below 51 mm diameter. The 330905-00-09-05-02-CN delivers voltage signals with supply sensitivity below 2 mV/V, allowing automated shutdown logic and predictive maintenance software to receive real-time rotor movement data in compact installation spaces.

Applications

Measure radial vibration on centrifugal compressors
With a 1.5 mm linear range and 1.0 mm gap setting, 330905-00-09-05-02-CN tracks shaft displacement on small rotors below 51 mm diameter. The 50 Ω output feeds vibration values directly into monitoring racks and plant DCS for continuous machine supervision.

Monitor thrust position in bearing housings
The 90 mm case and M10×1 mounting thread allow 330905-00-09-05-02-CN to be installed through compressor or turbine thrust bearing covers. Axial movement is converted into voltage for trip logic when rotor movement exceeds configured limits.

Generate phase reference for speed channels
The PPS probe tip of 330905-00-09-05-02-CN reads a keyway or notch to produce Keyphasor pulses. With supply sensitivity below 2 mV per volt, PLC speed cards and overspeed protection modules receive clear timing signals.

Install in narrow side view mounting areas
The 0.5 m miniature coaxial ClickLoc cable and compact sensing head enable 330905-00-09-05-02-CN placement in packaged compressor skids and process gas equipment where larger probes cannot be inserted.

Specifications

Competitive Advantage

Mount close to hot process casing
The −52 °C to +177 °C operating range allows 330905-00-09-05-02-CN installation directly on compressor housings and turbine bearing brackets without remote brackets.

Connect directly to monitoring cards
Because 330905-00-09-05-02-CN provides a standard 50 Ω signal, condition monitoring modules and machine protection systems accept the output without signal converters.

Prevent cable loosening during operation
The miniature coaxial ClickLoc connector of 330905-00-09-05-02-CN locks the probe cable, keeping electrical contact while equipment vibrates.

Measure small targets in compact machines
The sensing tip design and 1.5 mm measuring span allow 330905-00-09-05-02-CN to detect flat targets below 15 mm width, enabling vibration monitoring on compact rotating equipment.

Support field wiring connection
330905-00-09-05-02-CN accepts 0.2 to 1.5 mm² field wiring, allowing direct termination into junction boxes and control panels in automated plants.
