Product Overview

• The 330190-075-00-00 is an Extended Temperature Range (ETR) extension cable from Bently Nevada.
• This 3300 XL series cable ensures accurate signal integrity between sensors and monitors.
• It features a robust design for use in high-temperature industrial applications.

Core Technical Specifications

• Brand & Model: Bently Nevada 3300 XL ETR.
• Cable Length: 7.5 meters (24.6 feet) for flexible installation.
• DC Resistance (RCORE): 1.65 Ω ± 0.25 from center conductor to center conductor.
• DC Resistance (RJACKET): 0.49 Ω ± 0.10 from outer conductor to outer conductor.
• Capacitance: 69.9 pF/m typical for stable signal performance.

Performance and Measurement

• Linear Range: 2 mm (80 mils), starting from 0.25 mm from the target.
• Recommended Gap Setting: -9 Vdc for radial vibration, about 1.27 mm (50 mils).
• The system supports field wiring up to 305 meters between the sensor and monitor.
• Users must check frequency response graphs for signal rolloff with long cables.

Installation Guidelines

• Use 0.2 to 1.5 mm² (16 to 24 AWG) wire, preferably a 3-conductor shielded triad cable.
• Observe a minimum cable bend radius of 25.4 mm (1.0 inch).
• Apply a maximum connector torque of 0.565 N•m (5 in•lbf) to prevent damage.
• The 3300 XL 8 mm components are interchangeable with non-XL 3300 parts.

Construction and Material

• Standard Cable: 75Ω triaxial with FEP insulation.
• ETR Cable: 75Ω triaxial with PFA insulation for higher temperatures.
• Connectors use gold-plated brass or beryllium copper for excellent conductivity.
• Extension cable weighs 34 g/m, while the armored version weighs 103 g/m.
