Bently Nevada 330500 Series Technical Notes

The Evolution of 330500 Architecture

Early variants (330500-00-00 through 330500-03-XX) used a single-ended BNC output and were designed for direct connection to the 7200 Series monitors. As the 3500 Series platform became the industry standard in the late 1990s, Bently Nevada introduced connector variants with 2-pin MIL-C-5015 style connectors and extended cable options to accommodate panel-mount and remote-mount installations. The -07-04 variant (330500-07-04) represents the mature, field-proven configuration with a 4-pin connector, 5-meter integral cable, and stainless steel housing rated for IP67 ingress protection.

With the 3500 Series now in its extended lifecycle phase and the introduction of the System 1 software platform, the 330500 series remains fully supported as a primary input transducer. No direct next-generation replacement has been announced; the series is expected to remain in production through at least 2030 per Bently Nevada lifecycle documentation.
