The Bently Nevada 21747-085-01 is a high-performance proximity probe extension cable designed for seamless signal transmission in industrial condition monitoring systems, specifically engineered to complement Bently 3300 and 3500 series proximity probes. With a precise 8.5-meter (27.9-foot) length and non-armored construction, this cable balances flexibility and durability, facilitating easy installation in space-constrained industrial environments while reducing tripping hazards. Crafted from premium conductive materials with FEP insulation and a braided copper shielding layer, it ensures reliable performance across a wide operating temperature range of -40°C to +70°C (-40°F to +158°F), making it suitable for harsh conditions including temperature fluctuations, moisture, and industrial contaminants. Equipped with miniature coaxial ClickLoc connectors as standard, it establishes secure, low-loss connections between proximity probes and proximitor units, supporting a frequency response of 0 Hz (DC) to 10 kHz for accurate transmission of static and dynamic displacement signals. The advanced electromagnetic shielding minimizes interference from surrounding electrical equipment, maintaining signal integrity for precise gap-to-voltage measurements (linear range of 80 mils/2 millimeters) critical for rotating machinery monitoring. Fully compliant with API 670 standards and compatible with Bently 3300 XL and 3500 series monitoring systems, it integrates seamlessly into condition monitoring setups for gas/steam turbines, compressors, pumps, electric motors, and generators. As a U.S.-manufactured original equipment component, it undergoes rigorous testing to ensure long-term reliability, supporting predictive maintenance programs by delivering consistent data on shaft vibration, axial position, and rotational dynamics. Backed by a 12-month factory warranty, it offers a cost-effective solution for extending the reach of proximity transducer systems without compromising measurement accuracy or system efficiency.
