Bently Nevada 16925-12 330400 Series Interconnect Cables

Description

16925-12 specifies a 12-foot (3.6 m) 3-conductor shielded 22 AWG (0.5 mm2) interconnect cable, configured with a 3-socket plug at one end and terminal lugs at the other end. This configuration is used for transmitting high-frequency vibration signals from Bently Nevada 330400 and 330425 accelerometer transducers to permanent monitoring systems or dynamic signal analyzers.

The cable features a 22 AWG (0.5 mm2) conductor size, a protective shield to minimize electromagnetic interference (EMI), and terminal lugs for secure termination at the cabinet or receiver end. Unlike the heavier 18 AWG variant (130539) or the armored version (16710), the 16925 cable series provides a lightweight and flexible cabling option for standard industrial installations within protective conduit or enclosures. The 12-foot length is standard-configured to support intermediate-distance routing between the sensor and local junction boxes.

Features

• Conductor Configuration: 3-conductor shielded cable featuring 22 AWG (0.5 mm2) wire size for optimal signal integrity in high-frequency vibration monitoring applications.
• Cable Length: 12 ft (3.6 m) standard length, providing the ideal distance for field installations requiring run-ups from bearing housings to local enclosures.
• Terminations: 3-socket plug connection at one end to mate directly with 330400/330425 sensors, and terminal lugs at the opposing end for terminal block integration.
• Noise Mitigation: Integrated shielding protects delicate dynamic signals against electromagnetic and radio-frequency interference (EMI/RFI).
• Flexible Routing: Lightweight construction allows for easier bending and pulling through protective conduits or cable trays.

Applications

This interconnect cable is deployed across critical rotating machinery in demanding industrial environments, including:

• Power Generation: Steam, gas, and hydro turbine bearing casing monitoring.
• Oil and Gas: Centrifugal compressors, pumps, and gearboxes where casing acceleration is monitored.
• Petrochemical: Reciprocating machinery and fans requiring API 670 compliant measurements.
• General Industrial: Balance of plant rotating machinery casing vibration protection.

Installation Guidelines

To ensure precise signal transmission and reliable operation in heavy industrial applications, follow these physical routing and electrical termination practices:

• Conduit Protection: Install the interconnect cable in a protective conduit or dedicated cable trays to guard against mechanical damage, cutting, or crushing in harsh environments.
• Cable Routing: Avoid routing the signal cable adjacent to high-voltage power lines or variable frequency drive (VFD) cables to prevent electrical noise coupling.
• Grounding: Ensure the cable shield is properly terminated at the monitoring system or local junction box terminal strip to maintain a single-point ground, preventing ground loop noise.
• Mating Integrity: Ensure the 3-socket plug is fully threaded and seated onto the accelerometer connector. It is recommended to implement IP54 ingress protection or better at the mating point for outdoor environments.
