BENTLY 79492-01

Product introduction

The BENTLY NEVADA 79492-01 is a high-performance extension cable assembly, specifically engineered as a critical component of the 3300 XL proximity monitoring system. As an integral part of BENTLY NEVADA’s proven machinery protection solutions, this cable bridges the gap between proximity probes and proximitor sensors, ensuring reliable signal transmission in industrial environments.

In machinery health monitoring systems, the integrity of the signal path between probes and processing units is paramount. The 79492-01 is designed to preserve the accuracy of vibration, position, and speed data captured by 3300 XL probes, delivering it to proximitors like the 330180-91-05 without degradation. Its robust construction and shielding make it suitable for harsh industrial settings, where electromagnetic interference, temperature extremes, and mechanical stress are common. By maintaining signal integrity, the 79492-01 enables precise condition monitoring, helping prevent equipment failures and optimize maintenance schedules.

Core advantages and technical highlights

Signal integrity preservation: The 79492-01 features a shielded twisted-pair design with 90% copper braid coverage, effectively minimizing electromagnetic interference (EMI) and radio frequency interference (RFI). This ensures that the low-level signals from 3300 XL probes remain accurate during transmission to proximitors like the 330180-91-05, even in environments with heavy electrical noise from motors or variable frequency drives.

Durable construction: The cable’s jacket is made from a flame-retardant, oil-resistant thermoplastic elastomer, capable of withstanding exposure to industrial fluids, abrasion, and extreme temperatures (-40°C to +121°C). This durability makes the 79492-01 ideal for installations in turbine enclosures, compressor rooms, and other harsh industrial zones.

Easy integration: With pre-terminated, mating connectors, the 79492-01 eliminates the need for field wiring and crimping, reducing installation time and human error. Its compatibility with 3300 XL probes and proximitors—including the 330180-91-05—ensures seamless integration into existing systems, maintaining the system’s calibration and measurement accuracy.

Typical application scenarios

In power generation facilities, the BENTLY NEVADA 79492-01 is widely used in steam turbine monitoring systems. Turbines operate at high speeds and temperatures, where even minor signal loss can compromise vibration data accuracy. The 79492-01 connects 3300 XL probes (installed on turbine bearings) to 330180-91-05 proximitors in control cabinets, ensuring that critical vibration and shaft position data is transmitted without distortion. This enables operators to detect early signs of bearing wear or misalignment, preventing catastrophic failures.

In chemical processing plants, the 79492-01 is deployed in centrifugal pump monitoring setups. Pumps are prone to vibration-induced damage due to cavitation or impeller imbalance. By linking proximity probes to proximitors, the cable ensures that vibration amplitudes are measured precisely, allowing predictive maintenance teams to schedule repairs before unplanned downtime occurs. Its oil-resistant jacket also makes it suitable for installations near lubrication systems.

Installation, commissioning and maintenance instructions

Installation preparation: Before installing BENTLY NEVADA 79492-01, ensure the installation path is free of sharp edges, excessive heat sources, or moving machinery that could damage the cable. Use cable ties or clamps (non-metallic, to avoid EMI) to secure the cable at 30cm intervals. Verify that connectors are clean and dry—use lint-free cloth and isopropyl alcohol to clean mating surfaces if needed. Power off the monitoring system before connecting the 79492-01 to probes or proximitors like the 330180-91-05 to prevent signal damage.

Maintenance suggestions: Inspect 79492-01 quarterly for signs of jacket damage, shield fraying, or connector corrosion. Check that cable clamps are tight but not over-crimped, as excessive pressure can damage the jacket. If signal degradation is detected (e.g., noisy readings on the 330180-91-05), test the cable with a multimeter for continuity and insulation resistance (minimum 100 MΩ at 500V). Replace the cable immediately if faults are found—use only genuine 79492-01 replacements to maintain system calibration.
