Bently Nevada 330703-000-060-90-02-00 3300 XL 11 mm Proximity Probe

Description

Option 000 (0 mm unthreaded length), Option 060 (60 mm overall case length), and Option 90 (9.0 m total length) specify the 330703-000-060-90-02-00 3300 XL 11 mm proximity probe, which features an M14 x 1.5 metric thread without armor and a standard cable with a miniature ClickLoc coaxial connector (Option 02). This specific configuration is used for non-contacting vibration and displacement measurements on machinery with fluid film bearings, offering standard metric installation where mechanical protection sleeving is unnecessary.

The probe is part of the 3300 XL 11 mm system, which offers a 3.94 V/mm (100 mV/mil) output and a 4.0 mm (160 mils) linear range. Because this variant features a 9.0 m total length, it connects directly to a 9.0 m Proximitor sensor, eliminating the need for an intermediate extension cable and reducing overall connector points in the sensor line.

Features

• M14 x 1.5 metric thread body option (330703) for direct integration into metric machine ports without armor.
• 0 mm unthreaded length (Option 000) to allow full thread engagement inside thin-walled machine casings.
• 60 mm overall case length (Option 060) providing a rigid probe body for stable mounting.
• 9.0 meter total length (Option 90) allowing direct routing to a 9.0 m Proximitor sensor.
• Miniature ClickLoc coaxial connector (Option 02) for standard signal hookup.
• Polyphenylene sulfide (PPS) tip material offering resistance to chemical corrosion and moisture ingress.

Applications

• Axial (thrust) position measurements on steam and gas turbines.
• Ramp differential expansion measurements on power generation turbines.
• Rod position or rod drop monitoring on reciprocating compressors.
• Tachometer, zero-speed, and Keyphasor phase reference measurements.
• Radial vibration and shaft displacement monitoring on fluid film bearings.

Installation Guidelines

To avoid binding during installation, ensure the probe thread engagement in the M14 x 1.5 port does not exceed 21 mm. Tighten the probe case to a recommended torque of 21.1 N-m (187 in-lb), taking care not to exceed the maximum rated limit of 63.3 N-m (560 in-lb). The FEP-insulated coaxial cable has a minimum bend radius of 25.4 mm (1.0 in). Protect all connector junctions with connector protectors or appropriate tape to prevent fluid contamination and maintain signal integrity.

Compliance and Certifications

Complies with the European Community Directive EMC Directive 2014/30/EU (via EN 61000-6-2 and EN 61000-6-4 standards) and RoHS Directive 2011/65/EU. When agency approvals are required, systems are certifiable under ATEX, IECEx, and North American drawing schemes (Option 00 indicates no hazardous area certification package is supplied with this specific orderable SKU).
