Quick Detail

Description

330905-08-13-10-12-CN 3300 NSv Proximity Probe is an eddy-current displacement sensor for automated rotating equipment monitoring. The 330905-08-13-10-12-CN uses an 80 mm unthreaded section and 130 mm overall case with M10×1 mounting and a 1.0 m FluidLoc miniature coaxial ClickLoc cable. The 330905-08-13-10-12-CN provides a 1.5 mm linear range with a 1.0 mm recommended gap and 50 Ω output for direct connection to machine protection modules and DCS input cards.

Operating from −52 °C to +177 °C, 330905-08-13-10-12-CN measures shaft radial vibration, axial thrust displacement, phase reference pulses, and low-speed rotation. The PPS sensing tip and AISI 304 stainless housing of 330905-08-13-10-12-CN allow installation in compressor casings and turbine bearing brackets. With supply sensitivity below 2 mV/V, 330905-08-13-10-12-CN transmits displacement voltage to shutdown interlocks and predictive maintenance software in compact mounting locations.

Applications

Measure radial shaft movement in compressors
330905-08-13-10-12-CN uses a 1.0 mm gap and 1.5 mm linear range to detect vibration on rotors smaller than 51 mm. The 50 Ω signal transmits directly to vibration monitors and DCS channels for continuous process tracking.

Monitor axial thrust in turbine bearings
The 130 mm case and M10×1 thread allow 330905-08-13-10-12-CN to record axial movement through bearing covers, providing voltage output to trip logic when thrust displacement exceeds limits.

Generate Keyphasor pulses for speed control
The PPS tip of 330905-08-13-10-12-CN reads a shaft keyway or notch, delivering phase reference pulses to PLC speed modules for rotation angle and overspeed calculations.

Confirm zero speed during shutdown
330905-08-13-10-12-CN can sense slow shaft rotation, allowing control systems to verify rotor stop and activate turning gear and lubrication sequences.

Install in tight counterbore locations
The 80 mm unthreaded section and 1.0 m FluidLoc cable allow 330905-08-13-10-12-CN to reach recessed compressor or turbine housings where standard probes cannot fit.

Specifications

Competitive Advantage

Mount directly on heated housings
The −52 °C to +177 °C rating enables 330905-08-13-10-12-CN to be installed near compressor or turbine casings without extensions.

Direct signal feed to monitoring systems
The 50 Ω output of 330905-08-13-10-12-CN connects directly to machine protection racks, removing the need for signal converters.

Secure cable connection under vibration
The miniature coaxial ClickLoc FluidLoc connector locks the probe cable, keeping the signal intact during machine operation.

Measure compact targets
The 1.5 mm linear span of 330905-08-13-10-12-CN detects flat targets under 15 mm and small rotor surfaces in confined spaces.

Simplify wiring into control panels
330905-08-13-10-12-CN accepts 0.2 to 1.5 mm² field wiring, allowing direct termination in plant junction boxes and automation cabinets.
