Bently Nevada 84661-22 Standard Armored Interconnect Cable

Description

The Bently Nevada 84661-22 is an armored interconnect cable designed for use with Bently Nevada velocity sensor systems and compatible vibration monitoring equipment. It features a 22 AWG two-conductor twisted shielded cable with durable armor for enhanced mechanical protection in industrial environments. The cable is fitted with a 2-socket moisture-resistant female connector on one end and terminal lugs on the other, providing a reliable connection between the sensor and monitoring or data acquisition systems. With a cable length of 22 ft (approximately 6.7 m), it is suitable for installations requiring additional routing distance while maintaining dependable signal transmission.

Frequently asked questions

Q:What is the Bently Nevada 84661-22？
A:The Bently Nevada 84661-22 is a 22-foot (approximately 6.7-meter) Standard Armored Interconnect Cable designed exclusively for connecting the 330505 Low Frequency Velocity Sensor to a machinery monitoring system, such as the 3500/46M Hydro Monitor.

Q:What are the Bently Nevada 84661-22 primary structural characteristics of this cable?
A:It is a two-conductor twisted, shielded 22 AWG cable with a cross-sectional area of 0.382 mm². The entire length is wrapped in heavy-duty stainless steel armor, which provides maximum mechanical defense against crushing and abrasion without requiring external conduits.

Q:Is the 84661-22 cable approved for use in explosion-proof or hazardous areas?
A:No. The official documentation explicitly warns that due to capacitance constraints associated with the low-frequency loop, this sensor and cable ecosystem is not approved for hazardous areas. 

Application areas

The Bently Nevada 84661-22 armored interconnect cable is explicitly designed to work with the 330505 Low Frequency Velocity Sensor. Because it connects this specific sensor to machinery protection monitors (like the 3500/46M Hydro Monitor), its application areas directly mirror the highly specialized industrial environments where low-frequency vibration monitoring is critical.

• Stator Core and Stator Frame Monitoring: It is routed to sensors mounted on the outer diameter of the stator core and frame to detect vibrations that could cause fretting and destroy winding insulation.
• High-Capacity Hydraulic Pumps: Large-scale water transport, irrigation, and flood-control pumping stations utilize this cable to monitor massive, slow-moving hydraulic pumps.
• Wide-Temperature Environments: It is deployed in zones experiencing extreme ambient operational temperatures ranging from -29°C to 121°C (-20°F to 250°F).
