2. Brand

This product belongs to a globally recognized industrial condition monitoring and machinery protection technology brand widely used in vibration monitoring, shaft displacement measurement, and predictive maintenance systems across power generation, oil & gas, petrochemical, metallurgy, and heavy industry sectors.

3. Product Series

3300 XL 8 mm Proximity Transducer System (Reverse Mount Type)

This series is designed for high-precision non-contact measurement of shaft vibration and position in critical rotating machinery such as turbines, compressors, pumps, and generators.

4. Product Introduction

The 330105-XX-XX-10-02-00 MOD 157310-07 is a modified version of the 3300 XL 8 mm reverse mount proximity probe system.

It uses eddy current sensing technology, enabling precise measurement of the distance between the probe tip and a conductive metallic shaft without physical contact.

The “10” configuration typically represents a 1.0 m system length class, suitable for compact to medium industrial installations.

The suffix MOD 157310-07 indicates a factory-modified or project-specific configuration variant, often used for OEM integration, retrofit replacement, or customized engineering requirements.

This probe is part of a complete system consisting of:

• Proximity probe
• Extension cable
• Proximitor signal conditioner

Together they form a continuous vibration monitoring chain for rotating machinery protection and predictive maintenance.
