Description

The 84661-75 is a standard armored interconnect cable designed for use with Bently Nevada High Temperature Velomitor Systems (HTVS), specifically the 330750 and 330752 series. This cable features stainless steel armor protection over a shielded 22 AWG (0.382 mm2) cable, providing mechanical robustness for demanding industrial environments. The 75 indicates a factory-configured length of 75 feet. This interconnect cable is engineered to maintain signal integrity between the HTVS sensor and the monitoring instrumentation. It is equipped with a moisture-resistant female connector at the HTVS transducer end and standard ring lugs at the monitor termination end. The armored design offers increased abrasion resistance, making it suitable for installations where cabling requires protection from physical hazards or heavy industrial activity.

Features

• Standard Armored Interconnect Cable (84661 series)
• Length: 75 feet (factory configured)
• Construction: Stainless steel armor over shielded 22 AWG (0.382 mm2) cable

Installation Guidelines

• Ensure the cable is routed in conduit where possible to provide maximum mechanical protection.
• The moisture-resistant connector at the HTVS end must be securely tightened to maintain seal integrity.
• Maintain a minimum bend radius of 51 mm (2.0 in) to prevent damage to the internal conductors and shielding.
• Secure the cable using appropriate mounting clamps or cable ties, ensuring it is not pulled tight against sharp edges.
• Grounding: Ensure the cable shield is properly terminated at the monitoring system to minimize electromagnetic interference (EMI).
