Product Overview

The Bently Nevada 330730-080-01-00 is a 3300 XL 11 mm Extension Cable. This armored cable connects a 3300 XL 11 mm probe to its Proximitor Sensor. As a result, it provides robust mechanical protection for demanding industrial environments.

The 3300 XL 11 mm probe comes in varying probe case configurations. For example, these include armored and unarmored ½-20, ⅝-18, M14 x 1.5 and M16 x 1.5 probe threads. Meanwhile, the reverse mount 3300 XL 11 mm probe comes standard with either ⅜-24 or M10 x 1 threads. All components of the transducer system have gold-plated brass ClickLoc connectors. Furthermore, these connectors lock into place, preventing the connection from becoming loose.

Ordering Information Breakdown

Armored Cable Construction

The -01 option specifies armored cable without a connector protector. The armor consists of flexible AISI 302 stainless steel with an FEP outer jacket. For this reason, the 330730-080-01-00 provides superior mechanical protection in harsh industrial environments. However, note that no connector protector is included with this option.

Connector Features

All components of the transducer system have gold-plated brass ClickLoc connectors. These connectors lock into place, preventing the connection from becoming loose. In addition, the patented TipLoc molding method provides a robust bond between the probe tip and the probe body. Similarly, the probe cable is securely attached to the probe tip utilizing the patented CableLoc design. Consequently, it provides 330 N (75 lb) pull strength.

Temperature Range

The 330730-080-01-00 handles extreme temperatures effectively.

• Operating and Storage Temperature: -52°C to +177°C (-62°F to +351°F).

Linear Range and Gap Setting

The 3300 XL 11 mm proximity system provides an extended linear range. For optimal performance, follow these parameters.

• Linear Range: 4.0 mm (160 mils).

• Linear Range Begins: Approximately 0.5 mm (20 mils) from target.

• Linear Range Extends: 0.5 to 4.5 mm (20 to 180 mils) (approximately -1 to -17 Vdc).

• Extended DSL Range: 0.5 to 5.0 mm (20 to 200 mils) (-1 to -19 Vdc).

• Important Note: The extended DSL range is not applicable when using zener barriers.

• Recommended Gap Setting: 2.5 mm (100 mils).

Field Wiring Guidelines

Field wiring connects the Proximitor Sensor to the monitor. For proper installation, adhere to these specifications.

• Wire Size: 0.2 to 1.5 mm² (16 to 24 AWG).

• Recommendation: Use three-conductor shielded triad cable.

• Maximum Length: 305 meters (1,000 feet) between Proximitor Sensor and monitor.

• Note: See the frequency response graph for signal rolloff at high frequencies when using longer field wiring lengths.

Mechanical Specifications

The 330730-080-01-00 uses high-quality materials throughout its construction.

• Probe Tip Material: Polyphenylene sulfide (PPS).

• Probe Case Material: AISI 304 stainless steel (SST).

• Probe Cable Specification: 75 Ω triaxial, fluoroethylene propylene (FEP) insulated.

• Probe Lengths Available: 1, 5, or 9 meters.

Locknut Feature

The 3300 XL 11 mm probe comes standard with a locknut with pre-drilled safety wire holes. Therefore, safety wire can be installed to prevent loosening under vibration.

Reference to Other Cable Options

3300 XL Probes and Extension Cables can also be ordered with a FluidLoc cable option. This option prevents oil and other liquids from leaking out of the machine through the cable's interior. Additionally, the connector protector option provides additional protection of the connectors in a humid or moist environment. Connector protectors are recommended for all installations. Nevertheless, note that the 330730-080-01-00 includes neither FluidLoc nor connector protector. For these features, select the appropriate -03 or -10 options instead.

Silicone Tape Note: Silicone tape is also provided with each 3300 XL extension cable. It can be used instead of connector protectors. However, silicone tape is not recommended in applications where the probe-to-extension cable connection will be exposed to turbine oil.

Calibration Note

Proximitor Sensors are supplied by default from the factory calibrated to AISI 4140 steel. Calibration to other target materials is available upon request.
