Bently Nevada 330930-045-01-05 Cable

Bently Nevada 330930-045-01-05 NSv Extension Cable

This 330930-045-01-05 extension cable belongs to the 3300 NSv transducer family from Bently Nevada. It links NSv proximity probes to their matching Proximitor Sensors in machinery protection systems. The cable measures 4.5 metres (14.8 feet) and carries stainless steel armor with an FEP jacket.

Key Technical Specifications

The cable uses 75 Ω coaxial construction with fluoroethylene propylene (FEP) insulation. Its typical capacitance reaches 69.9 pF/m (21.3 pF/ft). Additionally, the center conductor resistance is 0.220 Ω/m (0.067 Ω/ft), while the shield resistance is 0.066 Ω/m (0.020 Ω/ft).

Furthermore, the armor consists of flexible AISI 302 stainless steel with an FEP outer jacket. This construction shields the cable from mechanical damage in demanding industrial settings. The connector material is gold-plated brass for stable signal transfer.

Mechanical and Environmental Parameters

The 330930-045-01-05 operates within a temperature range of -52°C to +177°C (-62°F to +351°F). Its maximum rated tensile strength reaches 220 N (50 lb) at three critical points: probe case to probe lead, probe lead to extension cable connectors, and probe case to stainless steel armor.

Moreover, the linear range measures 1.5 mm (60 mils). This range begins at approximately 0.25 mm (10 mils) from the target and extends to 1.75 mm (70 mils), corresponding to roughly -1 to -13 Vdc. The recommended gap setting is 1.0 mm (40 mils).

Installation Guidelines

First, confirm that the extension cable length plus the probe length equals the Proximitor Sensor total length. This matching requirement ensures accurate signal calibration across the measurement loop. Incorrect lengths will produce unreliable readings.

Next, connect the extension cable between the NSv probe and the Proximitor Sensor. The gold-plated brass connectors push and lock firmly into position. Route the armored cable away from excessive heat and secure it with suitable clamps.

Additionally, verify the field wiring between the Proximitor Sensor and the monitor. Use three-conductor shielded triad cable with a maximum length of 305 metres (1,000 feet). Field wiring accepts 0.2 to 1.5 mm² (16 to 24 AWG) conductors, or 0.25 to 0.75 mm² (18 to 23 AWG) with ferrules.

Finally, review the frequency response graphs when using longer field wiring lengths. Signal rolloff occurs at high frequencies, so plan cable routing accordingly to preserve measurement accuracy.
