Quick Detail

Description

The 330704-000-040-10-02-05 3300 XL 11 mm Proximity Probe is a high-precision non-contact displacement sensor designed for demanding industrial automation and machinery protection systems. As part of the 3300 XL proximity probe family, this 11 mm proximity probe delivers a calibrated sensitivity of 3.94 V/mm (100 mV/mil), enabling accurate vibration and position monitoring in rotating equipment operating under severe mechanical and environmental conditions.

With an overall case length of 40 mm, M14 x 1.5 threaded probe body, and 1.0 meter standard cable, the 330704-000-040-10-02-05 probe integrates easily into turbine housings, compressor frames, and automation control panels. The larger 11 mm probe tip provides an extended linear measurement range compared to 8 mm probes, making it ideal for axial position, thrust monitoring, and differential expansion measurements in fluid film bearing machines.

This 3300 XL 11 mm proximity probe is engineered for long-term reliability in automation systems. It features 99.9% braided copper shielding for excellent electromagnetic interference rejection, IP67 environmental protection, and stable performance across a wide -40°C to +85°C operating temperature range. The Miniature coaxial ClickLoc connector ensures secure signal transmission, reduces installation errors, and improves system uptime in continuous operation environments.

Designed as a modern replacement for legacy 7200-series transducer systems, the 3300 XL 11 mm proximity probe supports upgraded condition monitoring architectures when used with compatible monitoring platforms. Its robust mechanical construction, precision output characteristics, and automation-ready design make it a critical sensing component for advanced vibration monitoring, predictive maintenance, and machinery automation solutions.

Applications

Axial Thrust Position Monitoring in Steam Turbines

The 3300 XL 11 mm proximity probe is widely used for axial thrust measurements in steam turbines, where accurate shaft position control is critical. With its 3.94 V/mm sensitivity and extended linear range, the probe detects minute axial movement changes, enabling early detection of thrust bearing wear and preventing costly turbine shutdowns.

Differential Expansion Measurement in Large Rotors

In thermal power plants, the probe supports ramp and differential expansion monitoring by measuring relative shaft movement during startup and load changes. The 40 mm probe body and M14 thread allow stable mounting close to high-temperature zones while maintaining measurement accuracy under thermal stress.

Reciprocating Compressor Rod Position Detection

The 330704-000-040-10-02-05 proximity probe is applied to rod position and rod drop monitoring in reciprocating compressors. Its non-contact measurement principle ensures precise detection of rod movement without mechanical wear, improving compressor reliability and safety in automated process plants.

Tachometer and Zero Speed Measurement Systems

In automation control systems, the probe is used for speed reference and zero-speed detection. The stable output signal and high shielding effectiveness allow accurate rotational speed feedback, even in electrically noisy industrial environments.

Phase Reference and Keyphasor Signal Generation

The 3300 XL 11 mm proximity probe provides reliable phase reference signals for vibration analysis. Its consistent signal integrity supports advanced diagnostic functions such as orbit analysis and phase comparison in automated machinery monitoring platforms.

Specifications

Competitive Advantage

Extended Linear Measurement Range

Compared to standard 8 mm probes, the 11 mm sensing tip offers a longer linear range, allowing accurate measurement of larger shaft movements without signal saturation. This reduces sensor replacement frequency in high-displacement automation applications.

High Environmental and Temperature Resistance

With an IP67 rating and operation from -40°C to +85°C, the probe maintains performance in dusty, humid, and high-temperature environments. This significantly lowers failure rates in outdoor installations and harsh industrial automation systems.

Superior Signal Stability and EMI Protection

The 99.9% braided copper shielding minimizes electromagnetic interference, ensuring clean signal transmission to monitoring systems. This enhances data accuracy for condition monitoring and predictive maintenance algorithms.

Secure Mechanical and Electrical Connection Design

The ClickLoc connector system and controlled 21 mm maximum thread engagement improve installation reliability and prevent loosening due to vibration. This mechanical stability translates directly into improved measurement consistency over long operating cycles.

Seamless Integration with Modern Automation Platforms

Designed to replace legacy 7200-series probes, the 3300 XL 11 mm proximity probe supports modern monitoring architectures. Its standardized output and mechanical compatibility simplify system upgrades while improving overall automation efficiency and diagnostic capability.
