3300 XL 11 mm Proximity Probe
Model: 330801-28-00-070-03-02
Brand Information
Brand: Bently Nevada
Series: 3300 XL 11 mm Proximity Transducer System
Product Category: Non-Contact Eddy Current Proximity Probe
Product Type: Shaft Vibration, Position and Displacement Monitoring Sensor
The 330801-28-00-070-03-02 is a high-performance industrial proximity probe designed for continuous monitoring of critical rotating machinery. As part of the 3300 XL 11 mm series, this probe is engineered to provide highly accurate non-contact measurements of shaft vibration, shaft displacement, axial position, eccentricity, and rotor dynamic behavior.
This model is widely used in machinery protection and condition monitoring systems where operational reliability, equipment safety, and predictive maintenance are essential. The probe combines robust mechanical construction with advanced sensing technology, allowing it to operate reliably in harsh industrial environments.
Product Introduction
The 330801-28-00-070-03-02 proximity probe utilizes eddy current sensing technology to detect the distance between the probe tip and a conductive target surface. During operation, the probe generates a high-frequency electromagnetic field. Variations in the distance between the probe and the monitored shaft alter the electromagnetic field, producing an output signal proportional to shaft movement.
The probe performs measurements without physical contact, eliminating friction and wear while maintaining long-term measurement accuracy. This non-contact operating principle makes the sensor particularly suitable for monitoring high-speed rotating equipment where traditional contact-based measurement methods are impractical.
The larger 11 mm probe design offers increased sensing capability and improved measurement stability in demanding applications. The probe is commonly installed in turbines, compressors, generators, pumps, motors, gearboxes, and other critical machinery where continuous monitoring is required to prevent unexpected failures and costly downtime.
Its durable construction enables reliable operation in environments exposed to vibration, temperature fluctuations, oil contamination, humidity, and electromagnetic interference.
