Quick Detail

Description

The 330101-00-45-10-12-CN 3300 XL 8 mm Proximity Probe is used in industrial automation systems for shaft displacement and vibration measurement. The 330101-00-45-10-12-CN converts the distance between the probe tip and a conductive surface into a proportional output voltage for real-time monitoring of rotating equipment.

The 330101-00-45-10-12-CN provides a 2 mm linear range and a total length of 1.0 meter, suitable for turbines, compressors, and fluid-film bearing machines. A 3/8-24 UNF threaded probe case with 0.563 in maximum thread engagement supports direct mechanical installation in automated machinery.

Designed for harsh environments, the 330101-00-45-10-12-CN operates from -52°C to +177°C. The miniature ClickLoc connector with FluidLoc cable reduces oil leakage along the cable path. With 50 Ω output resistance and supply sensitivity below 2 mV/V, the 330101-00-45-10-12-CN delivers accurate signal transmission to automation control and condition monitoring systems. CSA, ATEX, and IECEx approvals allow the 330101-00-45-10-12-CN to be used in hazardous-area automation applications.

Applications

Shaft Vibration Measurement in High-Speed Turbines

The 330101-00-45-10-12-CN is applied to measure radial shaft vibration in steam and gas turbines operating at high rotational speeds. With a defined 2 mm linear range, the 330101-00-45-10-12-CN converts micro-level shaft displacement into proportional voltage output, allowing automation systems to detect vibration changes caused by imbalance or misalignment. The operating temperature range of -52°C to +177°C enables the 330101-00-45-10-12-CN to be installed close to turbine bearings.

Axial Shaft Position Monitoring in Compressors

Mounted near thrust bearings, the 330101-00-45-10-12-CN tracks axial shaft movement in centrifugal and axial compressors. The 3/8-24 UNF threaded case and 0.563 in maximum thread engagement allow the 330101-00-45-10-12-CN to be securely installed in compressor housings, providing continuous axial position signals for automated protection logic.

Rotational Speed Reference for Control Systems

When used with a Keyphasor target, the 330101-00-45-10-12-CN supplies speed reference signals for control and monitoring systems. The 50 Ω output resistance and supply sensitivity below 2 mV/V allow the 330101-00-45-10-12-CN to deliver repeatable pulse signals to automation controllers for accurate speed calculation.

Bearing Clearance Monitoring in Rotating Equipment

The 330101-00-45-10-12-CN monitors bearing clearance changes in fluid-film bearing machines. With controlled extension cable capacitance of 69.9 pF/m, the 330101-00-45-10-12-CN maintains predictable signal behavior over its 1.0 meter length, supporting long-term automated condition monitoring.

Specifications

Competitive Advantage

Direct Mechanical Mounting Without Adapters

The 330101-00-45-10-12-CN features a 3/8-24 UNF threaded probe case with zero unthreaded length, allowing direct installation into machinery without additional mounting hardware. This reduces installation time and ensures fixed probe positioning within automated systems.

Operation Near High-Temperature Process Zones

With an operating range up to +177°C, the 330101-00-45-10-12-CN can be deployed near hot bearings and process equipment where standard probes cannot be installed, supporting continuous automated measurement.

Controlled Signal Output Under Power Variation

Low supply sensitivity of less than 2 mV/V allows the 330101-00-45-10-12-CN to limit output change caused by supply voltage fluctuation, ensuring consistent signal input to automation control and protection systems.

Reduced Fluid Migration Through Cable Structure

The FluidLoc cable design used in the 330101-00-45-10-12-CN restricts oil movement inside the cable, preventing fluid leakage from machinery and supporting long-term automated operation.

Use in Hazardous Industrial Automation Areas

CSA, ATEX, and IECEx approvals allow the 330101-00-45-10-12-CN to be installed in explosion-risk environments, enabling vibration and position monitoring within hazardous automation zones.
