Product Overview

The Bently Nevada 16925-35 is a high-integrity signal transmission assembly specifically designed for the interconnection of vibration sensors and proximity transducers within Turbine Supervisory Instrumentation (TSI) systems. This 35-foot cable serves as a vital communication link, delivering raw analog data from the machine-mounted sensor to the monitoring rack with minimal attenuation. By utilizing a shielded, low-capacitance design, the 16925-35 preserves the sensitivity of the transducer signal, allowing for the precise detection of mechanical anomalies such as rotor unbalance, shaft misalignment, and bearing wear. Its construction is optimized for the electrical requirements of the 3300 series and related monitoring platforms, ensuring that predictive maintenance data remains accurate in high-interference industrial environments.

FAQ

Q: Is the 16925-35 cable shielded against electrical noise?

A: Yes, the cable features a robust internal shield designed to prevent electromagnetic interference (EMI) from large motors or power lines from distorting the low-level vibration signal.

Q: What is the significance of the "35" suffix in the model number?

A: The -35 suffix denotes the factory-calibrated length of 35 feet. Maintaining specific cable lengths is often critical for system impedance matching in proximity probe setups.

Q: Can this cable be used with the 3500 Series monitoring system?

A: Yes, the 16925-35 is fully compatible with the Bently Nevada 3500 rack system when paired with the appropriate transducer and proximity sensor inputs.

Q: Does the jacket protect against industrial contaminants?

A: The 16925-35 is manufactured with a high-durability jacket that provides resistance to common industrial chemicals, moisture, and oil exposure found on machine decks.

Q: How does this cable impact the accuracy of my vibration readings?

A: Because it is engineered to specific Bently Nevada electrical standards, it ensures that the 200 mV/mil (or similar) sensitivity of your transducer is maintained accurately over the full 35-foot distance.
