Product Overview: Bently Nevada 330190-075-00-00

The 330190-075-00-00 connects a 3300 XL proximity probe to its Proximitor sensor. Specifically, this extension cable is part of the 3300 XL Extended Temperature Range family. The 330190-075-00-00 uses 75Ω triaxial cable for superior signal integrity. Furthermore, it features gold-plated connectors for reliable electrical contact. As a result, the cable is fully interchangeable with non-XL 3300 components.

Technical Specifications

The 330190-075-00-00 has a nominal length of 7.5 meters (24.6 feet). Consequently, this length option is indicated by the “075” in the part number. The cable option “00” designates standard cable construction. Likewise, agency approval option “00” means no special certification is required. Finally, the cable is made in the U.S.A.

• Cable Length: 7.5 meters (24.6 feet)

• Impedance: 75Ω nominal

• Construction: Triaxial (center + inner shield + outer shield)

• Insulation: FEP (fluoroethylene propylene)

• Connector Material: Gold-plated brass or beryllium copper

• Max Connector Torque: 0.565 N•m (5 in•lbf)

The 330190-075-00-00 has specific DC resistance values. For instance, center conductor to center conductor resistance is 1.65 ± 0.25 Ω. Similarly, outer conductor to outer conductor resistance is 0.49 ± 0.10 Ω. Typical capacitance is 69.9 pF per meter (21.3 pF per foot). Therefore, these values ensure consistent performance with 3300 XL proximity probes.

Electrical Characteristics

The 330190-075-00-00 maintains signal quality over its full length. In particular, the linear range for the complete system is 2 mm (80 mils). This range begins at approximately 0.25 mm (10 mils) from the target. Moreover, the linear range extends from 0.25 to 2.3 mm (10 to 90 mils). Thus, the corresponding voltage range is approximately -1 to -17 Vdc.

Recommended Settings for the 330190-075-00-00:

• Radial Vibration Gap: -9 Vdc

• Physical Gap at -9V: Approximately 1.27 mm (50 mils)

• Linear Range Start: 0.25 mm (10 mils)

• Linear Range End: 2.3 mm (90 mils)

• Target Material: 4140 steel (typical)

The 330190-075-00-00 works with standard 3300 XL 8 mm probes. As a result, these components are electrically interchangeable with 5 mm probes. Physical interchangeability also exists when bend radius is observed. However, the minimum cable bend radius is 25.4 mm (1.0 inch). Consequently, exceeding this radius may damage the cable internally.

Temperature Range

The 330190-075-00-00 uses standard FEP insulation for most applications. Specifically, operating and storage temperature range is -52°C to +177°C. Therefore, this covers the vast majority of industrial machinery monitoring needs. Nevertheless, for higher temperature applications, order the extended range version.

• Standard Cable Range: -52°C to +177°C (-62°F to +350°F)

• ETR Cable Range: -52°C to +260°C (-62°F to +500°F)

• Note: This model is standard cable (option 00)

• FEP Insulation: Suitable for most industrial environments

• PFA Insulation: Required for temperatures above 177°C

The 330190-075-00-00 is not rated for cryogenic applications. Specifically, the lower limit of -52°C is the minimum safe operating temperature. Therefore, do not expose the cable to temperatures below this limit.

Physical Characteristics

The 330190-075-00-00 has a lightweight construction for easy installation. For example, standard cable weighs 34 grams per meter (0.4 oz per foot). Thus, the total cable weight is approximately 255 grams. Additionally, connectors are gold-plated for corrosion resistance.

• Standard Cable Weight: 34 g/m (0.4 oz/ft)

• Armored Cable Weight: 103 g/m (1.5 oz/ft)

• Total Weight (approx): 0.26 kg (0.57 lbs)

• Connector Plating: Gold over brass or beryllium copper

• Minimum Bend Radius: 25.4 mm (1.0 inch)

• Outer Jacket Color: Typically gray or black

The 330190-075-00-00 uses triaxial construction with two shields. Specifically, the inner shield carries the signal return path. Meanwhile, the outer shield provides additional noise protection. As a result, this design rejects electromagnetic interference effectively.

Field Wiring Guidelines

The 330190-075-00-00 connects to field wiring at the Proximitor sensor. For best results, use 3-conductor shielded triad cable for field wiring. Wire gauge range is 0.2 to 1.5 mm² (16 to 24 AWG). Furthermore, tinned copper field wiring is recommended for best results.

Field Wiring Specifications for the 330190-075-00-00:

• Wire Type: 3-conductor shielded triad

• Wire Gauge: 16 to 24 AWG

• Material: Tinned copper recommended

• Max Field Wiring Length: 305 meters (1000 feet)

• Signal Rolloff: Occurs at high frequencies with long runs

The 330190-075-00-00 field wiring connects the Proximitor to the monitor. Specifically, maximum length between the Proximitor and monitor is 305 meters. However, longer field wiring causes signal rolloff at high frequencies. Therefore, see frequency response graphs for specific attenuation values.

Installation Guidelines

Install the 330190-075-00-00 with attention to bend radius limits. Specifically, do not bend the cable tighter than 25.4 mm (1.0 inch). Use smooth bends to avoid internal conductor damage. Finally, connect the extension cable between the probe and Proximitor.

Key Installation Points for the 330190-075-00-00:

• Connector Torque: 0.565 N•m (5 in•lbf) maximum

• Bend Radius: Minimum 25.4 mm (1.0 inch)

• Cable Support: Use insulated clamps every 0.5 meters
