Quick Detail

Description

The 330103-02-10-05-02-05 3300 XL 8 mm Proximity Probe is a high-performance eddy current transducer specifically engineered for precision industrial automation applications. Designed to measure both static (position) and dynamic (vibration) displacements, this probe produces an output voltage directly proportional to the distance between the probe tip and the monitored conductive surface. With a 2 mm (80 mils) linear range, 50 Ω output resistance, and supply sensitivity below 2 mV per volt, it ensures accurate and stable measurements across extreme conditions. The probe features a 100 mm overall case length with 20 mm minimum unthreaded length and M10x1 threaded case, providing robust installation flexibility. Enhanced mechanical strength is achieved through patented TipLoc molding and CableLoc design, delivering 330 N (75 lbf) pull strength for secure probe-cable attachment. Optional FluidLoc cables prevent fluid ingress, ensuring reliable operation in harsh environments. This probe supports CSA, ATEX, and IECEx approvals, complies with API 670 standards, and is fully backward-compatible with 3300 series components for simplified maintenance and seamless system upgrades. Ideal for vibration monitoring, shaft position detection, and Keyphasor reference in turbines, compressors, and other rotating machinery.

Applications

Turbine and Generator Vibration Detection down to 2 μm
330103-02-10-05-02-05 is used to detect vibration on high-speed turbines and generators, measuring vibration amplitudes as low as 2 μm. With an 8 mm probe diameter and 50 Ω output, 330103-02-10-05-02-05 captures small mechanical changes early, allowing automated systems to schedule maintenance before bearing or rotor damage increases.

Shaft Displacement Measurement within 2 mm Range
Designed for pumps and compressors, 330103-02-10-05-02-05 measures shaft displacement accurately within a 2 mm working range. The linear output of 330103-02-10-05-02-05 supports precise alignment control, reducing shaft contact risk and avoiding unplanned shutdowns in continuous-process automation.

Rotational Speed and Phase Reference up to 10 kHz
330103-02-10-05-02-05 delivers clear output signals for Keyphasor and rotational speed measurement up to 10 kHz. This allows 330103-02-10-05-02-05 to track shaft phase and speed in automated control systems for compressors, steam turbines, and large motors.

Journal Bearing Condition Tracking during Operation
Installed near fluid-film bearings, 330103-02-10-05-02-05 monitors shaft motion patterns in real time. Changes in displacement captured by 330103-02-10-05-02-05 indicate lubrication loss or shaft offset, enabling early intervention before bearing surface damage occurs.

Operation from -52°C to +177°C with Fluid Blocking Cables
330103-02-10-05-02-05 operates across a temperature range of -52°C to +177°C, supporting use in petrochemical units, offshore platforms, and power plants. When combined with FluidLoc cable options, 330103-02-10-05-02-05 prevents fluid entry along the cable path, maintaining continuous signal transmission in automated monitoring systems.

Specifications

Competitive Advantage

Mechanical Probe-to-Cable Retention with 330 N Pull Force
330103-02-10-05-02-05 uses TipLoc and CableLoc mechanical locking to achieve a probe-to-cable pull strength of 330 N. This design keeps 330103-02-10-05-02-05 firmly connected under continuous vibration from rotating machinery, reducing signal interruption in automated monitoring systems such as turbines and compressors.

50 Ω Output Signal for Linear Shaft Measurement
The 330103-02-10-05-02-05 provides a 50 Ω output that supports linear displacement measurement across the full 8 mm probe range. With low supply sensitivity, 330103-02-10-05-02-05 maintains consistent signal scaling, meeting API 670 requirements for automated vibration and position control systems.

Direct Replacement for 3300 Series Probes without Recalibration
330103-02-10-05-02-05 can replace other 3300 XL 8 mm probes using existing extension cables. This allows automated protection systems to restore operation without bench calibration, reducing downtime during maintenance in power generation and process automation environments.

Operation from -52°C to +177°C with Fluid Blocking Option
Designed for harsh industrial conditions, 330103-02-10-05-02-05 operates reliably from -52°C to +177°C. When paired with FluidLoc cable options, 330103-02-10-05-02-05 prevents fluid migration through the cable jacket, supporting long-term use near oil, gas, or chemical process equipment.

Use in Hazardous Automation Areas with Global Certifications
330103-02-10-05-02-05 carries CSA, ATEX, and IECEx approvals, enabling installation in explosive or high-risk zones. These certifications allow 330103-02-10-05-02-05 to be integrated into automated safety and shutdown systems in refineries, offshore platforms, and petrochemical plants.
