The Bently Nevada 16710-10 is a specialized, high-performance accelerometer extension cable engineered to ensure reliable signal transmission from acceleration sensors to monitoring instrumentation. Its primary function is to convey the low-amplitude, high-frequency voltage signals characteristic of piezoelectric accelerometers with minimal degradation or noise interference. Constructed with two twisted, shielded conductors and a durable outer jacket, the cable is designed to reject electromagnetic interference (EMI) and radio frequency interference (RFI) common in industrial environments. This ensures high signal integrity, which is critical for the accurate condition monitoring of rotating machinery. The 16710-10 serves as a vital link in a complete vibration measurement chain, interfacing directly with vibration monitors such as the Bently Nevada 3500 Machinery Protection System to provide essential data for asset protection and predictive maintenance programs.

This cable is designed for mission-critical applications in demanding industrial sectors where machinery uptime and safety are paramount. It is extensively deployed in:
Oil & Gas: Monitoring critical assets such as centrifugal and reciprocating compressors, gas turbines, pumps, and fans to detect early signs of mechanical failure.
Power Generation: Providing essential vibration data from steam and gas turbines, boiler feed pumps, generators, and cooling tower fans as part of a comprehensive plant-wide machine condition monitoring strategy.
Is the 16710-10 cable compatible with all Bently Nevada accelerometers?
No, it is not universally compatible. The 16710-10 is specifically designed for use with Bently Nevada accelerometers that feature a 2-pin MIL-C-5015 style connector, such as the 330400 and 330425 models. It is imperative to cross-reference the accelerometer’s data sheet with the cable specifications to confirm connector type, pinout, and signal requirements. Using an incorrect cable can result in signal loss, noise contamination, or a complete failure to transmit data.
What are the critical installation best practices for this cable to maintain signal integrity?
To ensure optimal performance and prevent signal degradation, adhere to the following installation practices:
1. Shield Grounding: The cable shield must be terminated and grounded at the monitoring system end only. Do not ground the shield at the sensor end, as this can create a ground loop, introducing significant noise into the measurement signal.
2. Cable Routing: Route the cable away from high-voltage power lines, VFD motor leads, and other sources of significant electromagnetic interference. If crossing power cables is unavoidable, do so at a 90-degree angle to minimize inductive coupling.
3. Strain Relief: Secure the cable at both ends using appropriate clamps or ties to provide strain relief. This prevents tension on the connectors and internal conductors caused by machine vibration or thermal expansion, which could lead to intermittent or failed connections.
4. Bend Radius: Observe the minimum bend radius specified by the manufacturer to avoid kinking the cable, which can damage the internal conductors and shielding.
