Probe Proksimitas Bently Nevada 330704-00-100-10-01-05 3300 XL 11 mm

Description

The 330704-00-100-10-01-05 configuration specifies a 3300 XL 11 mm proximity probe with an M14 x 1.5 metric thread and integral stainless steel armor. This precise sensor configuration is defined by a 0 mm unthreaded length (Option 00), a 100 mm overall case length (Option 100), and a total probe length of 1.0 meter (Option 10) terminated with a miniature coaxial ClickLoc connector and an installed fluorosilicone connector protector (Option 01). Certified with multiple hazardous area approvals (Option 05), this eddy-current transducer is used within 3300 XL 11 mm monitoring chains to measure shaft vibration, rotor position, and axial displacement on critical rotating machinery.

Unlike standard non-armored probe variants, the 330704 model is built with a flexible stainless steel armor sleeve over its FEP-jacketed triaxial cable, safeguarding the conductor against physical abrasion, sharp bends, and harsh operating conditions. Its 11 mm sensor tip provides a wide 4.0 mm (160 mils) linear range, which accommodates larger thermal growth and physical movement than typical 8 mm probe systems, making it an excellent choice for major turbines, compressors, and generator installations with metric mounts.

Features

• Option 00 designates a 0 mm unthreaded portion for a fully threaded case length.
• Option 100 provides a 100 mm overall metric case length with M14 x 1.5 thread.
• Option 10 features a 1.0-meter (3.3 feet) total cable length with integrated stainless steel armor.
• Option 01 includes a miniature coaxial ClickLoc connector pre-installed with a protective fluorosilicone connector protector.
• Option 05 designates multiple agency approvals for hazardous environments, including ATEX, IECEx, and CSA certificates.
• Robust AISI 304 stainless steel case construction with a polyphenylene sulfide (PPS) probe tip.
• Flexible AISI 302 stainless steel armor with an outer FEP jacket delivers high mechanical defense and chemical immunity.
• Patented TipLoc molding and CableLoc designs resist mechanical strain, ensuring up to 330 N (75 pounds) of pull strength between the probe tip and lead.

Applications

• Shaft radial vibration and axial position monitoring on large industrial steam and gas turbines.
• Rotor displacement and thrust measurements in high-performance centrifugal compressors.
• Machine protection systems on rotating machinery with M14 x 1.5 metric mounting requirements.
• Harsh environments subject to abrasive mechanical wear, requiring armored coaxial cables.
• Hazardous location sites requiring intrinsically safe or non-sparking sensor installations.

Installation Guidelines

Establish exact physical alignment when mounting the M14 x 1.5 threaded probe case. Tighten the probe case to a recommended mounting torque of 21.1 N-m (187 in-lb), taking care not to exceed the absolute maximum limit of 63.3 N-m (560 in-lb) to prevent case deformation. Use a thickness gauge or voltage calibration at the Proximitor Sensor output to adjust the sensor gap to 2.5 mm (100 mils) under static shaft conditions. Maintain a bend radius of at least 25.4 mm (1.0 in) when routing the armored coaxial cable lead to prevent internal element stress. Ensure that the ClickLoc coaxial connection is free from oil and moisture prior to latching, and that the fluorosilicone connector protector is fully seated for maximum ingress protection.
