FAQ
-
What types of signals can the 89477-36 cable transmit?
The cable is designed to transmit low-level analog signals such as displacement, vibration, and proximity probe outputs, maintaining high signal fidelity over long distances. -
Is this cable compatible with all Bently Nevada monitoring systems?
Yes, the 89477-36 cable is fully compatible with Bently Nevada’s 3300 and 3500 series systems, as well as Proximitor and sensor assemblies used in vibration monitoring applications. -
How does the cable minimize electromagnetic interference?
The cable utilizes a dual-layer shielding system—a combination of foil and braided copper—that significantly reduces external EMI and crosstalk. -
What materials are used for insulation and protection?
The insulation is made from a high-performance fluoropolymer (such as Teflon), which provides excellent electrical insulation and resistance to heat, oil, and chemicals. -
Can the cable be used in environments with high mechanical vibration?
Yes, the 89477-36 cable is specifically built for environments with significant vibration exposure, maintaining reliable contact and stable signal transmission. -
What is the recommended method of installation?
The cable should be installed separately from high-voltage power cables to avoid interference, maintaining a minimum bend radius of 50 mm during routing. -
Is the cable resistant to oil and chemical exposure?
Yes, the outer jacket is formulated to resist oil, industrial solvents, and UV light, ensuring durability in challenging process conditions. -
Can the cable be custom-ordered in different lengths?
Absolutely. The Bently Nevada 89477 series offers multiple length options, and custom lengths can be ordered to suit specific installation requirements. -
How does the cable ensure consistent electrical characteristics?
Each cable is precision-manufactured and impedance-tested to ensure consistent resistance, capacitance, and signal attenuation across its full length. -
