پراب مجاورت 3300 XL بنتلی نوادا 330701-00-15-10-02-05 با اندازه 11 میلی‌متر

Description

Option 00 (0.0 in unthreaded length), Option 15 (1.5 in overall case length), and Option 02 (miniature coaxial ClickLoc connector, standard cable) specify this 3300 XL 11 mm proximity probe configuration - 330701-00-15-10-02-05. Operating as a non-contact eddy-current displacement sensor, it measures dynamic shaft vibration and static position on rotating machinery. The unarmored 1/2-20 UNF threaded steel body mounts directly in threaded machine casings or brackets to capture shaft movement with high precision.

This transducer component is used in 3300 XL 11 mm monitoring systems, pairing with a 330730 extension cable to match the calibration requirements of a 330780 Proximitor sensor. By combining a 1.0 m probe with a 4.0 m extension cable, the system achieves a total electrical length of 5.0 m. The standard ClickLoc coaxial connectors maintain low-resistance signal transfer, while the integrated Locknut with pre-drilled safety wire holes aids mechanical retention under vibration.

Features

• Thread configuration: 1/2-20 UNF-2A standard mount without protective armor.
• Unthreaded length: 0.0 inches (fully threaded case) for tight installation clearances.
• Overall case length: 1.5 inches for insertion into standard shallow machine housings.
• Coaxial cable: 1.0 meter length of 75 ohm triaxial, fluoroethylene propylene (FEP) insulated cable.
• Connector type: Miniature coaxial ClickLoc connector without connector protector.
• Approvals package: Option 05 offers multiple hazardous area certifications including CSA, ATEX, and IECEx.

Applications

• Steam and gas turbine shaft vibration and axial position measurement.
• Centrifugal compressor rotor position and thrust measurement.
• Industrial pump shaft displacement monitoring.
• Gearbox shaft motion and dynamic mechanical runout assessment.
• Keyphasor phase reference and speed measurements on rotating machinery.

Installation Guidelines

Positioning the probe requires establishing the standard 2.5 mm (100 mils) gap using a voltmeter to measure the corresponding -10 Vdc bias output. Standard mount 1/2-20 UNF threaded probes must be locked in place using the supplied locknut. The locknut has pre-drilled holes for safety wire to prevent loose rotation. The minimum bend radius for the probe cable is 25.4 mm (1.0 inch) to protect the internal triaxial conductors. Hand-tighten coaxial ClickLoc connectors; do not exceed 0.565 N-m (5 in-lb) of torque if utilizing mechanical tools. Exposing the probe to temperatures below -34 degC (-30 degF) may cause premature failure of the pressure seal.

Compliance and Certifications

Approved under Option 05 (Multiple Approvals) for hazardous areas, featuring certifications from CSA, ATEX, and IECEx. Under intrinsically safe installations (Ex ia IIC T4/T5 Ga), install the system with approved zener barriers or galvanic isolators per Bently Nevada drawing 141092. For non-incendive installations (Ex nA/ec IIC T4/T5 Gc), refer to drawing 140979. The product complies with European EMC Directive 2014/30/EU, EN 61000-6-2 (Industrial Immunity), EN 61000-6-4 (Industrial Emissions), and RoHS Directive 2011/65/EU.
