Bently Nevada 330130-045-01-CN Extension Cable

Product Introduction

The 330130-045-01-CN is a 3300 XL extension cable from Bently Nevada. It links a 3300 XL proximity probe to its Proximitor Sensor over a 4.5 metre run. Moreover, the armored cable option protects the conductors against abrasion, crushing, and rodent damage. This model carries the CN Country Specific Approval suffix. Additionally, the cable uses 75 Ω triaxial construction with FEP insulation for stable signal transfer. Each unit ships with silicone tape, which can replace connector protectors in dry locations. The 4.5 metre length suits bearing housings that sit at a moderate distance from the junction box.

Technical Specifications

The 330130-045-01-CN delivers predictable electrical performance across its 4.5 metre span. Specifically, the nominal DC resistance from center conductor to center conductor (RCORE) is 0.99 ± 0.15 ohms. Furthermore, the resistance from outer conductor to outer conductor (RJACKET) is 0.30 ± 0.06 ohms. The cable capacitance is typically 69.9 pF/m (21.3 pF/ft). In addition, the armored version weighs 103 g/m (1.5 oz/ft), giving a total weight of 0.618 kg.

Key ordering options break down as follows:

• 330130 = 3300 XL extension cable

• Cable length option 045 = 4.5 metres (14.8 feet)

• Connector protector and cable option 01 = Armored cable

• Approvals CN = Country Specific Approval

Mechanical and Environmental Parameters

The 3300 XL cable family uses a patented CableLoc design that provides 330 N (75 lbf) pull strength. Meanwhile, the TipLoc molding method creates a robust bond between probe tip and body. For field wiring, use 0.2 to 1.5 mm² (16 to 24 AWG) three-conductor shielded triad cable with tinned ends. The maximum field wiring length between the Proximitor Sensor and monitor is 305 metres (1,000 feet). Note that longer runs cause signal rolloff at high frequencies, so review the frequency response graphs.

The linear range is 2 mm (80 mils), starting at about 0.25 mm (10 mils) from the target and ending at 2.3 mm (90 mils). This range corresponds to roughly –1 to –17 Vdc. The system requires -17.5 Vdc to -26 Vdc with a nonincendive circuit, or -23 Vdc to -26 Vdc with barriers, at 12 mA maximum consumption. However, operation at a more positive voltage than -23.5 Vdc can reduce the linear range. Output resistance is 50 Ω, and supply sensitivity is less than 2 mV per volt. The cable also holds average scale factor (ASF) change under 3% after 56 days at 93% humidity per IEC 68-2-3.

Installation Guide

First, confirm the total cable run stays within the 305 metre field wiring limit. Next, route the armored cable away from sharp edges and hot surfaces, and respect a minimum bend radius of 25.4 mm (1.0 in). Then, connect the probe end and the Proximitor end with finger-tight torque only, never exceeding 0.565 N·m (5 in·lb). Besides, use the supplied silicone tape only in dry locations, since turbine oil degrades the tape over time. Finally, verify gap voltage and linear range during commissioning.

FAQ

Q1: What does the CN suffix mean on this extension cable?
A1: The CN suffix indicates Country Specific Approval. It confirms the cable meets the certification requirements of a designated country or region.

Q2: What is the nominal RCORE for the 4.5 metre cable?
A2: The center conductor to center conductor resistance is 0.99 ± 0.15 ohms, and the outer conductor resistance is 0.30 ± 0.06 ohms.

Q3: Can I use silicone tape instead of connector protectors?
A3: Yes, each cable includes silicone tape for that purpose. However, avoid silicone tape where turbine oil contacts the probe-to-extension connection.

Q4: What is the maximum field wiring length to the monitor?
A4: The limit is 305 metres (1,000 feet) between the 3300 XL Proximitor Sensor and the monitor, using 16 to 24 AWG shielded triad cable.

Q5: Does the package include certificates or a warranty?
A5: No. The packaging list covers the cable, silicone tape, and protective packing only.
