Quick Detail

Description

330905-00-12-10-02-00 3300 NSv Proximity Probe is an eddy-current displacement sensor used in automated rotating equipment monitoring. The 330905-00-12-10-02-00 has a 120 mm AISI 304 stainless housing with M10×1 thread and 1.0 m miniature coaxial ClickLoc cable for direct installation in machine bearing casings. The 330905-00-12-10-02-00 provides a 1.5 mm linear measuring range with a 1.0 mm recommended gap and 50 Ω output for connection to vibration monitors and DCS input cards.

Operating from −52 °C to +177 °C, 330905-00-12-10-02-00 measures shaft radial displacement, thrust position, and rotation reference signals. The PPS sensing tip of 330905-00-12-10-02-00 detects shafts under 51 mm diameter and flat targets below 15 mm width. With supply sensitivity under 2 mV/V, 330905-00-12-10-02-00 sends displacement voltage to machine protection logic, shutdown interlocks, and predictive maintenance software in automated compressor and turbine systems.

Applications

Measure shaft vibration on refrigeration compressors
Using a 1.0 mm gap and 1.5 mm linear range, 330905-00-12-10-02-00 detects rotor displacement on compact compressor shafts below 51 mm diameter. The 50 Ω signal connects to vibration monitoring modules and DCS input channels for continuous machine running supervision.

Monitor thrust position in turbine bearings
The 120 mm probe body and M10×1 thread allow 330905-00-12-10-02-00 installation through bearing covers. Axial movement is converted into voltage and used by trip logic to stop the turbine when thrust travel exceeds the configured value.

Provide phase reference pulse for speed control
The PPS probe tip of 330905-00-12-10-02-00 senses a keyway or notch on the shaft and produces Keyphasor pulses. PLC speed cards receive timing information for rotation angle and speed calculation.

Install in deep mounting holes of equipment casings
The long 120 mm case and 1.0 m ClickLoc cable allow 330905-00-12-10-02-00 to reach recessed counterbore mounting points inside compressor and process gas equipment housings.

Specifications

Competitive Advantage

Operate near heated machine housings
The −52 °C to +177 °C temperature rating enables 330905-00-12-10-02-00 mounting directly on bearing brackets and compressor casings without remote brackets.

Connect directly to protection monitoring racks
With a 50 Ω output, 330905-00-12-10-02-00 feeds displacement voltage straight into machine protection cards without additional interface devices.

Keep cable attached during machine vibration
The miniature coaxial ClickLoc connector on 330905-00-12-10-02-00 locks the cable and prevents loosening while rotating equipment runs.

Measure small shaft targets
The 1.5 mm measurement span allows 330905-00-12-10-02-00 to detect flat targets below 15 mm width and small rotor surfaces inside compact machinery.

Wire directly into field junction boxes
330905-00-12-10-02-00 supports 0.2 to 1.5 mm² field wiring, allowing quick termination into plant control cabinets and automation panels.
