Quick Detail

Description

The 84661-33 is a specialized Velomitor Interconnect Cable from Bently Nevada, engineered as a critical link for transmitting velocity-based vibration data with uncompromising accuracy. This high-performance interconnect cable is designed to form a reliable bridge between industrial-grade velocity sensors (Velomitor transducers) and a wide range of condition monitoring systems, including online protection hardware and portable data collectors. Its primary function is to ensure that the delicate analog signals representing machinery vibration velocity are conveyed from the sensor to the analyzer without degradation, preserving the integrity of the data essential for effective machinery diagnostics and protection.

This model, 84661-33, is constructed for durability and precise signal transmission in challenging industrial environments. It features a robust, shielded design with a specific total length option of 3.0 meters (9.8 feet), providing optimal reach for most machinery monitoring setups. The cable assembly is characterized by its specific dimensional configuration, with an overall case length of 40 mm and a minimum unthreaded length of 0 mm, ensuring a compact and secure physical interface. This design is crucial for maintaining a stable connection in high-vibration areas and for integration into space-constrained panels or direct machine mounting points.

Built to withstand the rigors of diverse operational settings, the 84661-33 exhibits excellent operating temperature resilience, functioning reliably from -35°C to +75°C. Its electrical performance is optimized for low signal loss, featuring a low typical extension cable capacitance of 53 pF/m and a stable output resistance. This minimizes signal attenuation and distortion over the cable's length, which is vital for accurate vibration velocity measurement. The cable's construction includes advanced shielding to guard against electromagnetic interference (EMI), ensuring that the signal remains pure even when routed near motors, drives, or other sources of electrical noise.

Applications:

This Velomitor Interconnect Cable is extensively used in power generation and heavy industrial facilities for continuous monitoring of mid-range to large rotating equipment like induced draft fans, boiler feed pumps, and large motors. Its 3.0-meter length is ideal for connecting velocity sensors mounted directly on bearing housings to nearby junction boxes or monitoring racks. The cable's robust shielding and stable electrical characteristics ensure that critical vibration velocity data, essential for detecting imbalance, misalignment, and rolling element bearing defects, is transmitted accurately to the protection system without interference from plant electrical noise.

The 84661-33 is a key component in predictive maintenance programs across general manufacturing, pulp and paper, and chemical processing plants. It is commonly used to connect portable data collectors or permanently installed online monitors to velocity sensors on critical process machinery such as mixers, conveyors, and compressors. Its durability and wide operating temperature range allow it to perform reliably in both indoor production halls and outdoor installations, providing maintenance teams with reliable data for periodic route-based data collection and trend analysis to schedule repairs before failures occur.

Specifications

Competitive Advantage

1.Optimized Signal Integrity for Accurate Velocity Monitoring

The 84661-33 is engineered for superior electrical performance, featuring a low typical extension cable capacitance and precise impedance characteristics. This design minimizes signal loss and distortion over its 3.0-meter length, ensuring that the subtle vibration velocity signals from the sensor are delivered to the monitoring system with high fidelity. This results in more accurate measurements, reliable trend data, and fewer false alarms, providing a clearer picture of machine health compared to generic or lower-specification cabling.

2.Robust Construction for Demanding Industrial Environments

Built to endure challenging conditions, this cable offers a reliable operating temperature range from -35°C to +75°C and is constructed with durable, shielded materials. This resilience makes it suitable for installation in areas subject to temperature extremes, moisture, oil mist, and physical abrasion. The robust design ensures long-term reliability and reduces the need for frequent replacement, lowering the total cost of ownership for the condition monitoring system and minimizing downtime associated with sensor cable failures.

3.Certified Compatibility and Ease of Integration

As an original Bently Nevada component, the 84661-33 guarantees perfect mechanical and electrical compatibility with Velomitor velocity transducers and related monitoring systems. Its possession of multiple agency approvals facilitates its use in a wide range of industrial projects without compliance concerns. The predefined 3.0-meter length and standard connector interface allow for quick, plug-and-play installation, saving valuable time during setup, commissioning, or sensor replacement, and ensuring a consistent, professional-grade connection every time.
