Quick Detail

Description

The 330103-10-12-05-11-05 3300 XL 8 mm Proximity Probe is a high-precision eddy current proximity probe engineered for advanced industrial automation and rotating machinery condition monitoring. As part of the 3300 XL proximity probe family, this 8 mm proximity probe delivers stable, repeatable displacement and vibration measurements by converting changes in distance between the probe tip and a conductive target into a proportional output voltage signal.

Designed for harsh automation environments, the 3300 XL 8 mm proximity probe supports both static position monitoring and dynamic vibration analysis on fluid-film bearing machines such as compressors, turbines, motors, and pumps. With a linear measurement range of 2 mm (80 mils) and output resistance of 50 Ω, the probe ensures accurate signal transmission over long distances, even in high-noise industrial installations.

The 5.0-meter FluidLoc cable with a miniature coaxial ClickLoc connector enhances reliability by preventing oil or liquid ingress through the cable core, a critical requirement in oil & gas, petrochemical, and power generation automation systems. The M10x1 threaded probe case with a maximum thread engagement of 15 mm allows secure mechanical mounting while maintaining compliance with API 670 guidelines for machinery protection systems.

Operating reliably across a wide temperature range of -52°C to +177°C, the 3300 XL 8 mm proximity probe maintains signal stability with less than 2 mV/V supply sensitivity, ensuring consistent measurement accuracy under fluctuating power conditions. Full CSA, ATEX, and IECEx approvals make this proximity probe suitable for hazardous-area automation applications where safety, precision, and long-term stability are essential.

Applications

Application 1: Turbine Shaft Vibration Monitoring

In steam and gas turbine automation systems, the 3300 XL 8 mm proximity probe measures radial shaft vibration with a 2 mm linear range, enabling early detection of imbalance, misalignment, or oil whirl. The 69.9 pF/m cable capacitance ensures stable signal integrity over the full 5-meter cable length.

Application 2: Compressor Thrust Position Control

For centrifugal and axial compressors, this proximity probe monitors axial shaft position to prevent thrust bearing overload. The high-temperature tolerance up to 177°C supports continuous operation in high-pressure compressor environments.

Application 3: Motor Shaft Displacement Monitoring

In critical electric motor automation systems, the probe provides real-time shaft displacement data with 50 Ω output resistance, allowing precise integration with vibration monitoring racks and PLC-based protection systems.

Application 4: Hazardous Area Machinery Protection

With CSA, ATEX, and IECEx approvals, the 3300 XL 8 mm proximity probe is ideal for explosion-risk zones in oil refineries and chemical plants, ensuring compliant vibration and position monitoring without additional signal conditioning.

Application 5: Speed and Keyphasor Reference Measurement

When paired with appropriate signal processing modules, the probe supports speed and phase reference measurements. The <2 mV/V supply sensitivity guarantees accurate timing signals even under power supply fluctuations.

Specifications

Competitive Advantage

Competitive Advantage 1: Superior Measurement Stability

The probe’s low supply sensitivity (<2 mV/V) minimizes output drift caused by voltage variations, improving long-term reliability in automation control systems compared to conventional proximity probes.

Competitive Advantage 2: Enhanced Mechanical Reliability

Patented TipLoc and CableLoc designs provide a 330 N (75 lbf) pull strength, significantly reducing failure risk due to cable stress or vibration in high-speed rotating machinery.

Competitive Advantage 3: Wide Environmental Operating Range

Operating from -52°C to +177°C, this 3300 XL 8 mm proximity probe outperforms standard sensors limited to narrower temperature ranges, making it suitable for extreme industrial automation conditions.

Competitive Advantage 4: Hazardous Area Certification

Full CSA, ATEX, and IECEx approvals eliminate the need for additional protective enclosures, reducing installation cost and complexity in hazardous industrial zones.

Competitive Advantage 5: System Interchangeability and Compliance

Complete interchangeability with other 3300 XL probes, extension cables, and Proximitor sensors ensures fast replacement and reduced downtime, while full API 670 compliance guarantees acceptance in critical machinery protection systems.
