  • Twisted Shielded Pair Construction
  • Hermetically Sealed Connectors
  • Flexible Routing Design
  • Optimized for Velocity Sensors
The Bently Nevada 84661-33 is a Standard Armored Interconnect Cable to maintain signal integrity for critical machinery protection systems. It is primarily used to connect 330505 Low-Frequency Velocity Sensors to monitoring systems like the Bently Nevada 3500 rack. Given that these sensors are often installed on large-scale rotating equipment such as hydroelectric turbines or slow-speed fans, the cable is engineered to withstand the extreme mechanical and environmental stresses typical of power generation and heavy industrial facilities.

The 84661-33 Bently Nevada Standard Armored Interconnect Cable may still be available for purchase and support from Amikon Limited beyond End-Of-Life (EOL) by the manufacturer (OEM).

The defining characteristic of the 84661-33 is its "armored" architecture. The stainless steel overbraid acts as a physical shield, preventing the internal signal conductors from being damaged by accidental impact or foot traffic during maintenance. Internally, the cable uses high-quality FEP insulation, which is not only resistant to extreme heat but also chemically inert to most industrial lubricants and synthetic oils. This ensures that the vibration signals—which are often very subtle at low frequencies—do not suffer from attenuation or distortion. By providing a stable, low-noise path for vibration data, the 84661-33 cable ensures that plant operators receive precise, real-time information regarding the mechanical health of their most critical assets.
  • Gas & Steam Turbines:Casing/strut vibration monitoring up to 400°C
  • Industrial Compressors:Centrifugal/reciprocating/process gas in extreme heat/tight spaces
  • High-Temperature Pumps & Motors:Absolute bearing vibration for boiler feed/hot oil pumps & motors
  • Fans & Blowers:Armored sensors for ID/FD & cooling tower fans in corrosive/outdoor environments

Minimum Bend Radius: Do not exceed a 51 mm (2.0 in) bending radius for the armored cable. For laying and handling processes, a larger radius (up to 15x cable diameter) is recommended to prevent internal copper fatigue.
Protection: Although armored, route the cable through a dedicated conduit where possible to protect against extreme physical impacts and minimize EMI from nearby high-voltage lines.
