FAQ

Q: Is the 16925-99 cable suitable for high-temperature environments near turbine housings?

A: Yes, the cable is rated for temperatures up to +120°C (+248°F), making it highly resilient against the ambient heat typically found near large rotating machinery.

Q: Why are twisted pairs used in this specific interconnect cable?

A: The three twisted pairs are designed to cancel out electromagnetic interference (EMI) from surrounding industrial equipment, ensuring the vibration signal remains clean and free of "noise" that could cause false alarms.

Q: Can this cable be used with non-Bently Nevada proximity sensors?

A: While designed primarily for Bently Nevada TSI systems, it can be used in any application requiring 24 AWG shielded twisted-pair cabling that matches its electrical impedance and voltage specifications.

Q: What is the benefit of the low pair-to-pair capacitance?

A: Low capacitance (≤30 pF/ft) prevents signal degradation and phase shifts over longer cable runs, which is vital for the high-frequency measurements required in vibration analysis.

Q: Does this cable require special tools for installation?

A: No, the 16925-99 uses standard industrial wiring practices, though it is recommended to follow Bently Nevada’s grounding and shielding guidelines to ensure optimal performance.
