System Compatibility, Alternative Models, and Differences
- System Compatibility:
Fully compatible with the Bently Nevada 3300 XL Proximitor Sensor (such as 330180) and 3300 XL Extension Cables. It is both electrically and physically interchangeable with non-XL 3300 series 5mm and 8mm transducer systems, providing backward compatibility compliant with API 670 standards. - Alternative Model (Metric Thread Equivalent):
330106-05-30-05-02-05 (3300 XL 8mm Reverse Mount Probe, Metric Series) - Key Differences between 330105 (English) and 330106 (Metric):
Thread Style and Size: The English 330105 utilizes standard 3/8-24 UNF-2A mounting threads, whereas the metric 330106 features M10X1 threads.
Installation Hardware: The 330105 model is supplied with a 7/16-inch hexagonal lock nut, whereas the metric 330106 version utilizes an M10 metric hexagonal nut.
Mechanical Configuration Coding: The English series uses fixed option codes (02=0.2 in unthreaded length approximation and 12=1.2 in overall case length approximation), while the metric series uses metric option codes (05=5.0 mm unthreaded length and 30=30 mm overall case length).
