FAQ
-
What type of connectors are used in the 89477-25 cable?
The cable is equipped with precision-engineered connectors featuring secure mechanical locking, ensuring reliable contact and minimizing signal loss during operation. -
Can this cable be used with non-Bently Nevada sensors?
While optimized for Bently Nevada systems, it can be used with compatible sensors following proper impedance matching and connection configuration. -
How is electromagnetic interference reduced in this cable?
The 89477-25 uses a dual-layer shield (foil and braided copper) to block external EMI and maintain clean signal transmission even in high-noise environments. -
Is the cable suitable for high-temperature industrial areas?
Yes, the cable operates effectively within a temperature range of -55°C to +200°C, making it ideal for use near turbines and other heat-generating equipment. -
What is the recommended bend radius during installation?
A minimum bend radius of 50 mm is recommended to prevent mechanical stress and maintain internal conductor integrity. -
Can the cable be customized to a different length?
Yes, Bently Nevada offers this cable series in various standard and custom lengths to meet different installation requirements. -
Is the 89477-25 cable resistant to oil and chemical exposure?
The cable features a special jacket formulation that is resistant to oils, industrial chemicals, and UV exposure for enhanced durability. -
What signal types can this cable transmit?
It supports low-level analog vibration and displacement signals typically used in proximity and vibration monitoring systems. -
Does the cable require periodic maintenance?
Generally, no routine maintenance is required; however, periodic inspection for mechanical wear or connector corrosion is recommended in harsh environments. -
Can the cable be routed alongside power cables?
It is not recommended. To maintain signal quality, the cable should be routed separately from high-voltage power lines to prevent electromagnetic coupling.
