Product Overview

The 330190-085-00-00 is a 3300 XL Extended Temperature Range (ETR) extension cable from Bently Nevada. To begin with, this device is made in the U.S.A. The cable length option is 085 for 8.5 meters (27.9 feet). The cable option is 00 for standard cable construction. Furthermore, the agency approval option is 00 because approvals are not required. Consequently, this cable is ideal for high-temperature industrial applications.

Electrical Specifications

The 330190-085-00-00 nominal DC resistance from center conductor to center conductor is 1.87 ± 0.28 Ω. Similarly, the resistance from outer conductor to outer conductor is 0.56 ± 0.11 Ω. The extension cable capacitance is 69.9 pF/m (21.3 pF/ft) typical. As a result, the 330190-085-00-00 maintains signal integrity over its 8.5 meter length.

Field Wiring Recommendations

Field wiring should use 0.2 to 1.5 mm² (16 to 24 AWG) conductors. Specifically, Bently Nevada recommends using 3-conductor shielded triad cable. In addition, tinned field wiring provides better corrosion resistance. The maximum length between the 3300 XL Proximitor Sensor and monitor is 305 meters (1,000 feet). However, see the frequency response graphs for signal rolloff at high frequencies. Therefore, keep field wiring as short as practical for best performance.

Linear Range and Gap Setting

The 330190-085-00-00 linear range is 2 mm (80 mils). More specifically, linear range begins at approximately 0.25 mm (10 mils) from target. The range extends from 0.25 to 2.3 mm (10 to 90 mils). This corresponds to approximately -1 to -17 Vdc. The recommended gap setting for radial vibration is -9 Vdc. This equals approximately 1.27 mm (50 mils). Thus, the 330190-085-00-00 supports standard 3300 XL probe configurations.

Cable Materials and Construction

The 330190-085-00-00 uses 75Ω triaxial cable construction. The standard cable uses fluoroethylene propylene (FEP) insulation. In contrast, the extended temperature range cable uses perfluoroalkoxy (PFA) insulation. Connector material is gold-plated brass or gold-plated beryllium copper. The minimum cable bend radius is 25.4 mm (1.0 in). Consequently, the 330190-085-00-00 must be handled carefully to avoid damage.

Temperature Ranges

The 330190-085-00-00 operating and storage temperature for standard cable is -52°C to +177°C (-62°F to +350°F). However, the extended temperature range cable operates from -52°C to +260°C (-62°F to +500°F). Therefore, the 330190-085-00-00 with PFA insulation suits extremely hot environments.

Physical Specifications

The 330190-085-00-00 standard extension cable weighs 34 g/m (0.4 oz/ft). In comparison, armored extension cable weighs 103 g/m (1.5 oz/ft). The maximum connector torque is 0.565 N•m (5 in•lbf). As a result, do not overtighten the connectors. The 330190-085-00-00 is designed for easy handling and installation.

Interchangeability

3300 XL 8 mm components are electrically interchangeable with non-XL 3300 components. Furthermore, they are physically interchangeable as well. However, the minimum permissible cable bend radius must be observed. Therefore, the 330190-085-00-00 works with existing 3300 systems when proper routing is maintained.

Compliance and Certifications

The 330190-085-00-00 complies with part 15 of the FCC Rules. Two conditions apply: first, this device may not cause harmful interference. Second, this device must accept any interference received. For EMC, it meets European Community Directive 2014/30/EU. Specifically, standards include EN 61000-6-2 for immunity and EN 61000-6-4 for emissions. Additionally, RoHS compliance follows Directive 2011/65/EU. Maritime compliance meets 2019 Rules for Classification. Finally, functional safety is rated SIL 2 with HFT = 0 and SIL 3 with HFT = 1. Consequently, the 330190-085-00-00 is suitable for safety-critical applications.

Installation Guidelines

First, inspect the 330190-085-00-00 for any shipping damage. Next, plan the cable route to avoid sharp bends. The minimum bend radius is 25.4 mm (1.0 in). Keep the cable away from high voltage power lines. Then, connect one end to the 3300 XL probe. Connect the other end to the 3300 XL proximitor. Hand-tighten the connectors to the maximum torque of 0.565 N•m. Do not use tools on the connector bodies. After that, secure the cable with strain relief clamps every 1 to 2 meters. Finally, verify the system gap and linear range after installation.

Frequently Asked Questions (FAQ)

Q1: What is the difference between standard and ETR cables?
ETR cables use PFA insulation instead of FEP. Therefore, the 330190-085-00-00 ETR version operates up to +260°C versus +177°C for standard.

Q2: Can I use this cable with non-XL 3300 components?
Yes, 3300 XL components are interchangeable. However, the 330190-085-00-00 must observe the minimum bend radius of 25.4 mm.

Q3: What is the maximum length for field wiring with this cable?
The maximum length between proximitor and monitor is 305 meters. The 330190-085-00-00 is the extension from probe to proximitor.

Q4: Is this cable suitable for safety instrumented systems?
Yes, the cable is rated SIL 2 (HFT=0) and SIL 3 (HFT=1). Therefore, the 330190-085-00-00 can be used in functional safety applications.

Q5: What is the recommended gap setting for radial vibration?
The recommended gap setting is -9 Vdc. This equals approximately 1.27 mm (50 mils) for the 330190-085-00-00 system.
