Tutto sui PLC: la CPU
A practical engineering guide to PLC CPU operation, from deterministic scan cycles and I/O image tables to memory, communications, diagnostics, redundancy, processor sizing, and reliable system...
The 21747-045-01 (21747-045-01) serves as a critical link within the Bently Nevada 3300 and 3300 XL Proximitor Sensor systems. This specific extension cable is engineered to maintain high-fidelity signal transmission between the proximity probe and the Proximitor sensor, ensuring precise vibration and position monitoring in demanding rotating machinery environments. The inclusion of stainless steel armor provides superior mechanical protection against physical abrasion and fluid exposure common in industrial settings.
| Feature | Technical Data |
| Manufacturer | Bently Nevada (Baker Hughes) |
| Model Number | 21747-045-01 |
| Cable Length | 4.5 Meters (Approximately 14.8 Feet / 177 Inches) |
| Armor Configuration | Flexible Stainless Steel Armor (Option 01) |
| System Compatibility | 3300 and 3300 XL 5mm & 8mm Proximity Transducer Systems |
| Connector Type | Miniature coaxial Gold-plated ClickLoc connectors |
| Capacitance | 69.9 pF/m (21.3 pF/ft) typical |
| Operating Temperature | -51 °C to +177 °C (-60 °F to +350 °F) |
| Minimum Bend Radius | 25.4 mm (1.0 in) |
Proper implementation of the 21747-045-01 requires ensuring that the combined length of the proximity probe and the extension cable matches the required system length of the Proximitor Sensor (typically 5.0 or 9.0 meters). This armored version is ideal for internal machine housing or exposed conduit runs where moisture, oil, or mechanical impact risks are present.
Can this cable be used with non-XL 3300 sensors?
Yes, the 21747-045-01 is backward compatible with standard 3300 series 5mm and 8mm systems, provided the total electrical length is calibrated correctly.
What is the benefit of the '01' Armor option?
The stainless steel braiding prevents the coaxial core from being crushed or kinked, which would otherwise alter the electrical capacitance and degrade the accuracy of vibration data.
