Quick Detail

Description

The 330104-03-12-05-02-05 3300 XL 8 mm Proximity Probe is a precision eddy current transducer designed for advanced industrial automation and condition monitoring. It provides an output voltage proportional to the distance between the probe tip and the conductive surface, enabling accurate measurement of both static shaft positions and dynamic vibrations. With a linear range of 2 mm (80 mils), 50 Ω output resistance, and supply sensitivity under 2 mV per volt, this probe delivers stable, high-fidelity readings even under extreme conditions. The M10x1 threaded probe case, 120 mm overall case length, and maximum 15 mm thread engagement provide robust installation options, while the patented TipLoc molding and CableLoc cable attachment ensure mechanical strength and 330 N (75 lbf) pull resistance. Optional FluidLoc cables prevent oil or fluid leakage from machinery. Operating reliably between -52°C and +177°C (-62°F to +350°F), the probe meets CSA, ATEX, and IECEx approvals, complies with API 670 standards, and is fully compatible with 3300 series transducers for simplified maintenance, interchangeability, and long-term system reliability.

Applications

Turbine and Compressor Vibration Detection below 2 μm
330104-03-12-05-02-05 is applied to turbines and compressors to measure vibration levels below 2 μm on high-speed rotating shafts. Using an 8 mm probe tip and a 50 Ω signal output, 330104-03-12-05-02-05 captures early vibration changes, allowing automation systems to trigger maintenance actions before mechanical damage develops.

Shaft Displacement Measurement within 2 mm Linear Range
For pumps and compressors, 330104-03-12-05-02-05 measures shaft position within a 2 mm linear operating range. The proportional output of 330104-03-12-05-02-05 supports precise shaft alignment during operation, reducing contact between rotating and stationary parts in continuous-process equipment.

Rotational Speed and Phase Signal up to 10 kHz
330104-03-12-05-02-05 provides Keyphasor and rotational speed signals up to 10 kHz for automated control systems. By tracking shaft phase and speed, 330104-03-12-05-02-05 enables accurate timing reference for protection and monitoring systems used in large motors and turbine trains.

Journal Bearing Shaft Motion Tracking
Installed near fluid-film bearings, 330104-03-12-05-02-05 monitors shaft movement patterns in real time. Variations detected by 330104-03-12-05-02-05 indicate imbalance, shaft offset, or lubrication loss, allowing maintenance teams to intervene before bearing surface wear increases.

Operation from -52°C to +177°C with Fluid Blocking Cables
330104-03-12-05-02-05 operates across temperatures from -52°C to +177°C, supporting use in petrochemical plants, power generation units, and offshore platforms. When paired with FluidLoc cable options, 330104-03-12-05-02-05 blocks fluid travel along the cable path, maintaining continuous signal output in demanding automation environments.

Specifications

Competitive Advantage

Probe-to-Cable Locking with 330 N Pull Force
330104-03-12-05-02-05 applies TipLoc and CableLoc structures to lock the probe tip and cable together with a 330 N pull force. This mechanical locking method allows 330104-03-12-05-02-05 to remain fixed during continuous vibration from turbines, compressors, and large motors, reducing signal interruption in automated monitoring systems.

50 Ω Output with Low Supply Sensitivity Control
The 330104-03-12-05-02-05 delivers a 50 Ω output signal with low supply sensitivity, supporting linear displacement measurement across the full 8 mm probe range. By maintaining proportional signal output under voltage variation, 330104-03-12-05-02-05 meets API 670 requirements for automated vibration and shaft position measurement.

Direct Replacement of 3300 Series Probes without Recalibration
330104-03-12-05-02-05 can be installed using existing 3300 series extension cables, allowing equipment to return to operation without bench calibration. This replacement method enables 330104-03-12-05-02-05 to reduce maintenance time during system upgrades in power generation and process automation facilities.

Operation from -52°C to +177°C with Fluid Blocking Cables
Designed for harsh operating conditions, 330104-03-12-05-02-05 supports continuous operation from -52°C to +177°C. When combined with FluidLoc cable options, 330104-03-12-05-02-05 blocks fluid travel along the cable path, supporting installation near oil, gas, and chemical process equipment.

Installation in Explosive Areas with CSA ATEX IECEx Approval
330104-03-12-05-02-05 holds CSA, ATEX, and IECEx approvals for use in explosive or high-risk locations. These approvals allow 330104-03-12-05-02-05 to be installed in automated protection and shutdown systems within refineries, offshore platforms, and critical industrial plants.
