Key Features and Benefits
The BENTLY 330980-51-00 delivers exceptional signal integrity through its double-layered shielding, which effectively blocks EMI from nearby electrical equipment—critical for maintaining the precision of proximity probe data. This shielding ensures that even subtle machinery vibrations or displacement measurements are transmitted accurately to monitoring systems, enabling early detection of potential failures.
Constructed from durable TPU, the BENTLY 330980-51-00 resists abrasion, oil, and chemical exposure, making it suitable for installation in dirty or corrosive environments such as refineries or chemical plants. Its flexibility allows for easy routing around machinery components without compromising structural integrity, simplifying installation in tight spaces.
Compatibility is another strength of the BENTLY 330980-51-00, as it is specifically engineered to work with Bently Nevada’s 3301 and 3300 series proximity probes, ensuring a secure, interference-free connection with monitoring modules like the 3300/18. This plug-and-play design reduces installation time and minimizes the risk of connection errors, enhancing overall system reliability.
With an IP67 rating when mated, the BENTLY 330980-51-00 also protects against dust and temporary water immersion, further extending its usability in outdoor or wet industrial settings.
Application Scenarios
The BENTLY 330980-51-00 finds its primary use in bridging the gap between proximity probes and monitoring systems in industries where machinery reliability is paramount. In power generation, it is widely deployed in coal-fired and gas turbine plants, connecting 3300 series probes on turbine shafts to 3500 monitoring racks located in control rooms—often several meters away. This ensures that critical data on rotor vibration and displacement reaches operators without distortion, supporting timely maintenance decisions.
In oil and gas refineries, the BENTLY 330980-51-00 is used with pumps and compressors, where its chemical resistance and EMI shielding protect against the harsh environment of hydrocarbon processing. It enables safe routing of signals from probes mounted on equipment to monitoring panels in explosion-proof enclosures, adhering to hazardous area regulations.
Chemical processing plants rely on the BENTLY 330980-51-00 to connect agitator and mixer sensors to central monitoring systems, even in areas with high levels of airborne contaminants. Its rugged design ensures consistent performance, preventing signal loss that could lead to incorrect machinery health assessments.
In marine applications, such as shipboard propulsion systems, the cable’s flexibility and water resistance make it ideal for routing through tight engine rooms, ensuring reliable data transmission from turbine probes to on-board monitoring systems.

Installation and Maintenance
Installation of BENTLY 330980-51-00 requires careful handling to avoid damaging the shielding or connectors. The cable should be routed away from high-voltage cables and motor leads to minimize EMI, using cable clips to secure it to machinery frames—avoiding sharp bends that exceed the 15 mm static radius. Ensure connectors are fully mated and tightened to achieve the IP67 rating, and verify that the cable length matches the distance between the probe and monitor to prevent excess slack or stretching.
For maintenance, inspect BENTLY 330980-51-00 every six months for signs of abrasion, cuts, or connector corrosion, especially in dirty or humid environments. Clean connectors with a dry cloth to remove debris, and check for signal degradation using a multimeter or Bently Nevada’s diagnostic tools. Replace the cable if shielding is damaged or if intermittent signal loss occurs, typically every 6-8 years under normal operating conditions to maintain optimal performance.
