Model: 330800-28-00-035-01-02
Brand Information
Brand: Bently Nevada
Product Series: 3300 XL 8 mm Proximity Transducer System
Product Type: Eddy Current Proximity Probe
Industry Classification: Rotating Machinery Monitoring and Protection Equipment
The 330800-28-00-035-01-02 is a high-precision proximity probe designed for continuous measurement of shaft vibration, shaft position, eccentricity, differential expansion, and other critical mechanical parameters in industrial rotating equipment. As an integral component of the 3300 XL monitoring platform, this probe delivers accurate and reliable non-contact measurements for machinery protection and predictive maintenance applications.
Product Introduction
The 330800-28-00-035-01-02 proximity probe is engineered for industrial environments where machinery reliability and operational safety are critical. Utilizing advanced eddy current sensing technology, the probe detects the distance between the probe tip and a conductive target surface without making physical contact.
