Quick Detail

Description

The 330104-00-08-50-12-00 3300 XL 8 mm Proximity Probe is an eddy current sensor engineered for displacement and vibration measurement in industrial automation and rotating equipment monitoring. The 330104-00-08-50-12-00 converts the distance between the probe tip and a conductive surface into a proportional voltage signal, allowing control systems to process real-time shaft movement data.

Designed with an M10×1 probe case thread and a maximum thread engagement of 15 mm, the 330104-00-08-50-12-00 supports accurate probe positioning during installation. An overall case length of 80 mm and a 5.0-meter FluidLoc cable enable routing through turbine skids and compressor frames while preventing oil migration along the cable path. The 330104-00-08-50-12-00 operates from –52°C to +177°C, making it suitable for high-temperature bearing housings in automated machinery.

With a 2 mm linear range, 50 Ω output resistance, and supply sensitivity below 2 mV/V, the 330104-00-08-50-12-00 delivers predictable signal behavior to proximity monitoring modules. Typical extension cable capacitance of 69.9 pF/m allows consistent signal transmission over the full cable length. The 330104-00-08-50-12-00 is commonly used for shaft position tracking, vibration monitoring, and speed reference input in automation-driven protection and control systems.

Applications

Measure Axial Shaft Position in Turbine Control Systems

The 330104-00-08-50-12-00 is installed near thrust bearings to measure axial shaft movement in steam and gas turbines. The 2 mm linear range of the 330104-00-08-50-12-00 allows control systems to track shaft displacement and trigger alarms when movement exceeds preset limits.

Monitor Radial Vibration on Fluid Film Bearings

Mounted adjacent to journal bearings, the 330104-00-08-50-12-00 detects radial shaft vibration caused by imbalance or mechanical wear. The 50 Ω output resistance and defined cable capacitance of the 330104-00-08-50-12-00 allow vibration signals to be transmitted accurately to monitoring processors.

Provide Speed Reference Signals for Rotating Equipment

When used with a suitable reference target, the 330104-00-08-50-12-00 supplies speed-related signals for compressors and generators. The low supply sensitivity below 2 mV/V ensures the 330104-00-08-50-12-00 maintains accurate signal output despite power supply variation.

Specifications

Competitive Advantage

Prevent Oil Migration Through Sensor Cabling

The FluidLoc cable design of the 330104-00-08-50-12-00 blocks oil and liquid movement inside the cable. This allows the 330104-00-08-50-12-00 to be installed in lubricated bearing housings without fluid leakage reaching control cabinets.

Support High-Temperature Machine Zones

With an operating range from –52°C to +177°C, the 330104-00-08-50-12-00 can be mounted directly in hot bearing environments. This temperature capability allows the 330104-00-08-50-12-00 to collect continuous measurement data without external cooling.

Enable Precise Mechanical Adjustment During Installation

The M10×1 threaded body, 15 mm maximum thread engagement, and 80 mm case length allow precise probe positioning. This mechanical structure enables the 330104-00-08-50-12-00 to maintain a controlled sensing gap in compact automated machinery layouts.
