Quick Detail

Description

The 330703-000-070-10-02-00 3300 XL 11 mm Proximity Probe is a high-precision non-contact displacement and vibration sensor designed for critical industrial automation and machinery protection systems. As part of the 3300 XL proximity probe family, this 11 mm proximity probe is engineered to deliver stable, repeatable measurements in demanding rotating equipment environments such as turbines, compressors, pumps, and generators. With a sensitivity of 3.94 V/mm (100 mV/mil), the probe supports accurate shaft displacement and vibration monitoring over an extended linear range, exceeding the capabilities of standard 8 mm proximity probes.

The 330703-000-070-10-02-00 proximity probe features an M14 x 1.5 threaded probe case, a 70 mm overall case length, and a 1.0 meter standard cable, making it suitable for compact installations while maintaining mechanical robustness. The probe utilizes a Miniature coaxial ClickLoc connector, ensuring secure electrical connections and minimizing signal loss in automated monitoring systems. Its 99.9% braided copper shielding effectively suppresses electromagnetic interference, which is essential for reliable data acquisition in industrial automation environments.

Designed for harsh operating conditions, the 3300 XL 11 mm proximity probe offers an operating temperature range of -40°C to +85°C and IP67-rated environmental resistance, providing dependable performance in dusty, humid, or oil-contaminated machinery enclosures. The probe is commonly integrated with condition monitoring and protection platforms to support predictive maintenance strategies, reduce unplanned downtime, and enhance asset lifecycle management. By combining mechanical durability, extended linear measurement range, and automation-ready signal stability, the 330703-000-070-10-02-00 3300 XL 11 mm Proximity Probe is an ideal solution for advanced industrial automation and rotating machinery health monitoring applications.

Applications

Application 1: Axial Thrust Position Monitoring in Steam Turbines

In steam turbine automation systems, the 3300 XL 11 mm proximity probe is used to measure axial shaft position with high accuracy. The extended linear range enabled by the 11 mm tip allows precise monitoring of thrust movement, even during load changes. With 3.94 V/mm output, control systems can detect micrometer-level axial shifts, helping prevent thrust bearing damage and improving turbine operational safety.

Application 2: Differential Expansion Measurement

For large steam turbines, differential expansion between rotor and casing is a critical parameter. The 330703-000-070-10-02-00 proximity probe provides continuous, non-contact measurement of ramp differential expansion. The stable signal performance and IP67 environmental resistance ensure reliable data under high temperature gradients, enabling automation systems to trigger alarms before mechanical interference occurs.

Application 3: Reciprocating Compressor Rod Position Monitoring

In reciprocating compressors, the probe is applied to rod position and rod drop measurements. The 1.0 meter cable length and M14 x 1.5 mounting thread simplify installation in confined compressor frames. Accurate displacement feedback supports automated shutdown logic, reducing the risk of cylinder or crosshead damage.

Application 4: Tachometer and Zero Speed Detection

The 3300 XL 11 mm proximity probe is widely used as a tachometer input in rotating machinery automation systems. Its fast response and high signal stability allow precise speed measurement and reliable zero speed detection, which is essential for safe startup and shutdown sequences in turbines and compressors.

Application 5: Phase Reference and Keyphasor Signals

As a phase reference sensor, the probe provides consistent Keyphasor signals for vibration analysis systems. The high shielding effectiveness (99.9% braided copper) minimizes electrical noise, ensuring accurate phase angle calculation and supporting advanced diagnostic algorithms in condition monitoring software.

Specifications
