The 16925-70 is a Bently Nevada 16925 Interconnecting Cable, defined by a 70-foot non-armored configuration within a series ranging customizable from 1.0 foot to 99 feet. The cable architecture utilizes a 3-conductor shielded 22 AWG tinned copper signal path protected by high-grade fluorinated ethylene propylene insulation and jacket layers. Its high-density continuous metal braided shield structure effectively blocks electromagnetic interference and radio frequency interference across the signal path, preventing data distortion and background noise injection in high-voltage industrial environments while maintaining an operating voltage threshold of 300 V to 600 V AC. This heavy-duty assembly operates reliably across an extended temperature scale from minus 55 degrees Celsius to plus 177 degrees Celsius.
The cable contains a high-density continuous metal braided shield
The configuration utilizes three-conductor 22 AWG tinned copper wires
The insulation and jacket materials consist of fluorinated ethylene propylene or flexible polyvinyl chloride
The 16925-70 cable establishes point-to-point electrical connectivity with Bently Nevada 330400 and 330425 accelerometer acceleration transducers, interfacing directly with 3500 series machinery protection frameworks or standard junction boxes. Field application deployment covers power generation, oil and gas, petrochemical processing, pulp and paper, and heavy manufacturing sectors for permanent vibration monitoring networks and periodic machinery diagnostics. It maps onto critical rotating equipment assets including steam and gas turbines, centrifugal compressors, high-pressure pumps, induction motors, and industrial generators. Mechanical integration requires routing separate from high-voltage power conduits and strong magnetic fields, incorporating single-point shield grounding at the monitoring instrument terminal block to complete the noise suppression circuit.

Thermal Power Generation Industry
Connects to accelerometers mounted on steam turbine generator casings, transmitting high-frequency vibration signals to 3500 monitoring cabinets without distortion inside power plant machine rooms rich in electromagnetic interference.
Oil and Gas Extraction Industry
Used for heavy-duty water injection pumps at offshore drilling platforms and onshore stations, utilizing the fluorinated ethylene propylene jacket to block penetration of mineral oils and crude oils containing chemical additives, securing signal transmission.
Petrochemical Industry
Deployed on casing vibration monitoring locations of charge gas compressors and high-pressure olefin monomer trains, utilizing the high-density braided shield to block radio frequency interference generated by nearby high-power variable frequency drives.
Nuclear Power Industry
Connects to accelerometers on reactor coolant pumps in nuclear islands or turbine trains in conventional islands, utilizing the mechanically locked 3-socket plug to withstand continuous high-frequency mechanical shocks and prevent connector loosening.
Hydroelectric Power Generation Industry
Used for casing vibration monitoring of upper and lower guide bearing housings on hydro-generator units, with jacket materials blocking chemical erosion from high-humidity moisture and synthetic lubricants inside bearing chambers.
Steel and Metallurgy Industry
Installed on external bearing pedestals of Blast Furnace Top Gas Recovery Turbine (TRT) units and large centrifugal blowers, maintaining electrical insulation of the 3-conductor signal path in environments rich in high temperatures and conductive iron powder.
Mechanical routing of the 16925-70 cable requires continuous physical separation from high-voltage power conduits and strong magnetic sources to maintain shield effectiveness. Proper configuration mandates single-point grounding of the braided shield strictly at the monitoring instrument terminal block, leaving the transducer end isolated to prevent ground loops. During field termination, the cable must maintain its minimum bend radius to prevent internal conductor damage, and the 3-socket plug must lock tightly onto the accelerometer interface to ensure a sealed connection against fluid ingress and signal loss.

Technical notes
Acting as a vital nervous system for machinery protection, the Bently Nevada 16925-70 cable connects 330400 and 330425 vibration sensors directly to monitoring systems to guarantee the flawless delivery of acceleration data. This heavy-duty cable is a staple in power, oil and gas, and chemical plants, serving as a frontline defense for critical rotating equipment like steam turbines, gas turbines, and massive industrial compressors.
What is the Bently Nevada 16925-70 interconnecting cable?
It is a high-quality 3-conductor shielded interconnect cable manufactured by Bently Nevada, specifically designed for vibration and condition monitoring systems of industrial rotating machinery to transmit critical data signals between sensors and monitoring modules.
What is the internal construction of the Bently Nevada 16925-70?
The cable features a 3-conductor shielded construction with a wire gauge typically of 22 AWG (0.5 mm²) copper conductors, complete with a braided shield to protect against industrial electromagnetic interference (EMI).
How do you correctly use the Bently Nevada 16925-70 cable?
Connect the 3-socket plug end of the cable to the vibration sensor (such as an accelerometer or Proximitor output), and connect the terminal lugs on the other end to the field junction box or monitoring system (such as the 3500 system) input.
What are the connector types at both ends of the Bently Nevada 16925-70?
One end is a 3-socket plug, and the other is terminal lugs.
Why does the 16925-70 require shielding?
The shielding blocks EMI and RFI, ensuring the weak vibration signal is transmitted without interference.
