Product Description
The 330930-040-01-00 is a 3300 XL 8mm Proximity Transducer System component from Bently Nevada, a Baker Hughes business. This specific part is an Extension Cable Assembly. It serves as a critical link between an 8mm eddy current proximity probe (sensor) and the monitoring system's proximitor (preamplifier). This cable is designed to carry high-frequency electrical signals with minimal loss and interference, ensuring accurate measurement of shaft vibration and position in critical rotating machinery. It features the proprietary ClickLoc connector system, which allows for tool-less, secure, and reliable connections.
Key Parameters and Specifications
The following table summarizes the key technical parameters for the 330930-040-01-00.
| Parameter | Specification / Value | Notes |
|---|---|---|
| Compatible System | Bently Nevada 3300 XL 8mm Proximity Transducer System | |
| Product Type | Extension Cable Assembly | Connects probe to proximitor. |
