Product Introduction
The Bently Nevada 16710-08 is an extension cable designed for use with 3300 Series proximity probe systems. It connects a 3300 Series 8 mm proximity probe to a 3300 Series proximitor (driver/demodulator), extending the reach between the probe (mounted near the machine shaft) and the proximitor (located in a junction box or control panel). The cable features a rugged, flexible design with Bently Nevada’s standard coaxial construction, ensuring high signal integrity and noise immunity over the extended length. The -08 suffix typically indicates a cable length of 8 feet (2.44 meters). This extension cable is fully compatible with 3300 Series probes and proximitors, and is commonly used in industrial machinery protection systems.

Application Scenarios
Extending Probe Reach in Large Machinery – Used on steam turbines, gas turbines, compressors, and pumps where the distance between the probe mounting point and the proximitor junction box exceeds the standard probe’s integral cable length (e.g., 0.5 m or 1.0 m). The 8 ft (2.44 m) extension allows flexible placement of the proximitor in a safer, more accessible location.
Retrofit and Maintenance – Replaces worn or damaged extension cables in existing 3300 Series installations, restoring signal quality without replacing the entire probe or proximitor.
Simplifying Wiring in Junction Boxes – Enables multiple probes to connect to a centrally located junction box, where proximitors can be mounted and powered, reducing field wiring complexity and improving organization.
Industrial Environments with Moderate Temperatures – Suitable for use in refineries, chemical plants, power stations, and steel mills where the cable is routed through conduit or cable trays away from extreme heat sources.
Temporary or Test Setups – Provides a convenient length for connecting probes to portable diagnostic instruments during machine troubleshooting, balancing, or startup validation.
