Excellent PLC
Description
The Bently Nevada 330101-20-39-10-02-05 is part of the 3300 XL 8 mm proximity transducer system. It provides a voltage output proportional to the distance between the probe tip and the target surface, enabling accurate static position and dynamic vibration measurements on rotating machinery. The system meets API 670 standards and is fully interchangeable with other XL and non-XL 5 mm and 8 mm components.
