Bently Nevada 330930-045-02-05 Extension Cable
Product Introduction
The 330930-045-02-05 is an extension cable from the Bently Nevada 3300 NSv series. This cable connects a proximity probe to a Proximitor Sensor. Moreover, it carries vibration and position signals in turbines, compressors, and other rotating machinery.
Maintenance teams choose this model for its stainless steel armor. The 330930-045-02-05 offers a 4.5 metre length, which equals 14.8 feet. In addition, the armor protects the cable from abrasion and crushing. Furthermore, multiple approvals allow use in regulated industrial environments.
Technical Specifications
The extension cable uses 75 Ω coaxial construction with fluoroethylene propylene (FEP) insulation. Its armor is flexible AISI 302 stainless steel without an FEP outer jacket. Additionally, the connectors are made of gold-plated brass.
Main parameters appear below:
Cable Length: 4.5 metres (14.8 feet) (red)
Connector and Cable Option: Stainless steel armor, without FEP jacket (blue)
Agency Approval: Multiple Approvals (red)
Capacitance: 69.9 pF/m (21.3 pF/ft) typical (blue)
Center Conductor Resistance: 0.220 Ω/m (0.067 Ω/ft)
Shield Resistance: 0.066 Ω/m (0.020 Ω/ft)
Operating and Storage Temperature: -51°C to +177°C (blue)
The 4.5 metre length gives a center conductor resistance near 0.99 ohms. Meanwhile, the shield resistance stays near 0.30 ohms. These values help technicians verify cable integrity after installation.
Mechanical and Environmental Parameters
Tensile strength reaches 220 N (50 lb) from probe case to probe lead. The same 220 N (50 lb) rating applies at the probe lead to extension cable connectors. Moreover, the probe case to stainless steel armor joint also holds 220 N (50 lb).
Operating and storage temperature spans -52°C to +177°C. The FEP insulation resists oil, moisture, and most industrial chemicals. Besides, the flexible AISI 302 armor shields the cable from mechanical damage.
Field wiring accepts 0.2 to 1.5 mm² (16 to 24 AWG). With ferrules, the range narrows to 0.25 to 0.75 mm² (18 to 23 AWG). Bently Nevada recommends a three-conductor shielded triad cable. The maximum field wiring length between the 3300 XL NSv Proximitor Sensor and the monitor is 305 metres (1,000 feet).
Linear range reaches 1.5 mm (60 mils). This range begins about 0.25 mm (10 mils) from the target and extends to 1.75 mm (70 mils). The recommended gap setting is 1.0 mm (40 mils).
Installation Guide
First, confirm the cable length and connector type against the system drawing. Next, add the extension cable length and the probe length together. Then, check that the total matches the Proximitor Sensor total length.
After that, mate the ClickLoc connectors until they lock. Route the armored cable away from sharp edges and hot surfaces. Finally, secure it with clamps and measure the DC resistance.
