Product Introduction
The Bently Nevada 16710-50 is an armored interconnect cable designed for use with 3300 XL and 3500 series proximity monitoring systems. It connects a 3300 XL 8 mm proximity probe (or similar) to the Proximitor sensor, serving as the extension element in a three-component system (probe – extension cable – Proximitor). This model has a length of 50 feet (15.24 meters) and features a coaxial, stainless steel armored construction. The cable is fully interchangeable with other Bently Nevada extension cables of the same length and maintains the system’s calibrated scale factor when used within total system length specifications.
The 16710-50 is particularly suited for long-distance signal routing from field-mounted probes to rack-mounted Proximitor units located in control rooms or instrument cabinets. It includes standard 3300 XL connectors on both ends and is supplied pre-tested for insulation resistance, capacitance, and continuity.

Application Scenarios
The 16710-50 is used where significant physical distance exists between the proximity probe mounting point and the Proximitor/driver location. Typical applications include:
Large steam turbines (power generation) – Routing signals from probes in the turbine casing and bearing housings to Proximitor units installed in a remote cabinet outside the turbine deck area.
Gas turbine compressor trains (oil & gas) – Connecting probes on gas compressors located outdoors to monitoring equipment inside a central control room, often across distances exceeding 10 meters.
Hydroelectric turbines – Extending signals from probes embedded in thrust bearings and guide bearings to monitoring racks positioned above the turbine pit or in adjacent galleries.
Large centrifugal blowers (steel, cement, mining) – Allowing Proximitor installation in clean, temperature-controlled enclosures while probes remain near high-temperature or dusty rotating shafts.
Paper mill rollers and calendars – Providing long cable runs from probes mounted on large drying rolls or press sections to vibration monitors located in a centralized machine condition monitoring system.
Retrofit and system expansion – Replacing shorter existing extension cables (e.g., 16710-10, 16710-25) to relocate Proximitor sensors without changing field-installed probes.
