Quick Detail

Description

The 330101-00-56-10-02-00 3300 XL 8 mm Proximity Probe from Bently Nevada is designed for precise position and vibration measurement in rotating machinery within industrial automation systems. The 330101-00-56-10-02-00 features a 3/8-24 UNF threaded case with a maximum thread engagement of 0.563 in and a minimum case length of 5.6 in. With a 1.0 meter standard cable and miniature coaxial ClickLoc connector, the 330101-00-56-10-02-00 supports efficient installation in confined equipment layouts.

Operating from –52°C to +177°C, the 330101-00-56-10-02-00 delivers a 2 mm linear range and 50 Ω output resistance, suitable for fluid-film bearing machines, Keyphasor reference, and speed measurement. Extension cable capacitance is typically 69.9 pF/m, ensuring accurate signal transmission in automation monitoring systems. The 330101-00-56-10-02-00 is widely applied in turbine, compressor, and motor protection solutions requiring eddy current proximity sensing.

Applications

Measure Radial Shaft Vibration Within 2 mm Linear Range

The 330101-00-56-10-02-00 provides a 2 mm (80 mils) linear measurement range, allowing precise monitoring of radial shaft vibration on fluid-film bearing machines. With a typical extension cable capacitance of 69.9 pF/m and a 1.0 meter total length configuration, the probe delivers accurate signal transmission over short routing distances, minimizing signal distortion. The 50 Ω output resistance ensures proper signal matching with vibration monitoring systems, making it suitable for turbines and compressors operating at high rotational speeds.

Monitor Axial Shaft Displacement Using Direct Proportional Voltage Output

Installed facing a thrust collar, the 330101-00-56-10-02-00 converts axial movement into a voltage proportional to displacement. With supply sensitivity of less than 2 mV change per volt variation in input voltage, the probe maintains consistent output even when power supply fluctuations occur. The 0.563 in maximum thread engagement supports secure mechanical mounting in thrust bearing assemblies.

Generate Keyphasor Reference Pulses for Phase Analysis

The 330101-00-56-10-02-00 can detect a keyway or once-per-turn shaft mark and generate a rotational reference signal. Operating across –52°C to +177°C, the probe maintains reliable pulse detection in high-temperature turbine casings. The miniature coaxial ClickLoc connector ensures tight electrical connection during high-frequency pulse transmission required for orbit and phase measurements.

Measure Rotational Speed in High-Temperature Industrial Zones

Using its wide operating temperature range of –52°C to +177°C, the 330101-00-56-10-02-00 performs speed measurement in steam turbines and gas compressors. The stable voltage output combined with 50 Ω impedance allows direct integration with monitoring modules without additional signal conditioning hardware.

Capture Transient Shaft Movement During Startup and Shutdown

During machine startup and coast-down, the 330101-00-56-10-02-00 records dynamic shaft motion within its 2 mm linear span. The probe’s 8 mm sensing diameter provides sufficient electromagnetic field coverage to track rapid displacement changes as the rotor passes through critical speeds.

Specifications

Competitive Advantage

Deliver Consistent Output With Less Than 2 mV/V Supply Sensitivity

The 330101-00-56-10-02-00 limits output variation to less than 2 mV for every 1 V change in supply voltage. For example, with a 24 V supply fluctuation of ±1 V, output drift remains under 2 mV, reducing false vibration alarms and minimizing recalibration requirements.

Operate Across –52°C to +177°C Without Signal Degradation

The 330101-00-56-10-02-00 supports installation in both sub-zero outdoor environments and high-temperature turbine housings. This 229°C total temperature span enables a single probe model to cover multiple equipment categories, reducing spare part inventory.

Maintain Secure Mechanical Engagement With 3/8-24 UNF Thread

Equipped with a 3/8-24 UNF thread and 0.563 in maximum thread engagement, the 330101-00-56-10-02-00 allows direct installation into standard American threaded mounting ports. The 5.6 in overall case length supports correct positioning while maintaining mechanical rigidity.

Ensure Reliable Signal Transmission With 50 Ω Output Resistance

The 330101-00-56-10-02-00 provides a controlled 50 Ω output resistance, matching standard coaxial transmission requirements. With 69.9 pF/m cable capacitance at 1 meter length, signal attenuation remains low, supporting accurate high-frequency vibration waveform acquisition.

Support Direct Field Wiring From 0.2 to 1.5 mm² Conductors

The 330101-00-56-10-02-00 accommodates field wiring sizes from 0.2 mm² to 1.5 mm² (16–24 AWG), enabling installation in both compact control panels and heavy-duty industrial cabinets without special terminal adapters.

Enable Installation in Restricted Equipment Spaces

With a 0.0 in minimum unthreaded length and 5.6 in case length, the 330101-00-56-10-02-00 fits into confined bearing housings where longer probe bodies cannot be used. The compact mechanical profile supports retrofit projects in legacy rotating equipment.
