Product Overview
How do you maintain precise vibration signal integrity when your 3300 XL Proximitor Sensor must be mounted far from the monitor? The Bently Nevada 330190-075-01-00 answers this with a 7.5-meter armored extension cable engineered for extended temperature range (ETR) applications. As part of the 3300 XL series, this cable ensures exact signal transmission between the Proximitor Sensor and monitor, preserving measurement accuracy in harsh industrial environments.
Key Features & Technical Specifications
The 330190-075-01-00 delivers engineering-grade precision through carefully controlled electrical parameters. Its 75Ω triaxial construction uses perfluoroalkoxy (PFA) insulation, enabling operation from -52°C to +260°C. The armored cable option adds mechanical protection without compromising flexibility, with a minimum bend radius of 25.4 mm. Below are the core specifications:
- Cable Length: 7.5 meters (24.6 feet)
- Cable Type: Armored, 75Ω triaxial, PFA insulated
- Nominal DC Resistance (RCORE): 1.65 ± 0.25 Ω
- Nominal DC Resistance (RJACKET): 0.49 ± 0.10 Ω
- Capacitance: 69.9 pF/m typical
- Temperature Range: -52°C to +260°C
- Minimum Bend Radius: 25.4 mm (1.0 in)
- Connector Material: Gold-plated brass or beryllium copper
- Maximum Connector Torque: 0.565 N·m (5 in·lbf)
- Weight: 103 g/m (armored)
These verified parameters ensure minimal signal attenuation and reliable performance in extended temperature applications.
Applications and Use Cases
This extension cable is ideal for gas turbines, steam turbines, and compressors where high temperatures near the probe demand ETR-rated components. In power generation, it connects 3300 XL 8 mm proximity probes to Proximitor Sensors, maintaining signal fidelity over 7.5 meters. Additionally, the armored construction protects against mechanical damage in crowded cable trays. For offshore platforms, the PFA insulation resists moisture and chemicals, ensuring long-term reliability.
Installation and Compatibility
Installation requires observing the 25.4 mm minimum bend radius to avoid damaging the triaxial cable. The gold-plated connectors provide low-resistance contacts; torque them to 0.565 N·m maximum. This cable is compatible with 3300 XL 8 mm probes and Proximitor Sensors, and it is electrically and physically interchangeable with non-XL 3300 5 mm and 8 mm components when the bend radius is respected. For field wiring, use 3-conductor shielded triad cable with tinned conductors, not exceeding 305 meters total length between sensor and monitor.
