Bently Nevada 330702-00-10-10-01-00 3300 XL 11 mm Proximity Probe

Description

Option 00 (0.0 inches unthreaded length), Option 10 (1.0 inch case length), and Option 01 (ClickLoc connector with connector protector) define this specific 3300 XL 11 mm proximity probe configuration — 330702-00-10-10-01-00. This 1/2-20 UNF threaded probe features integral stainless steel armor for physical protection in demanding industrial environments and a 1.0-meter total cable length.

Unlike the unarmored 330701 series, the 330702 probe includes an AISI 302 stainless steel armor jacket over the FEP-insulated coaxial cable to resist physical damage, shear forces, and abrasion. The inclusion of a ClickLoc coaxial connector with a pre-installed connector protector (Option 01) seals the cable-to-extension-cable connection against moisture, dust, and process fluids. The 11 mm probe tip provides an extended linear range of 4.0 mm (160 mils), making it suitable for larger-scale vibration and position measurements where standard 8 mm probes lack sufficient measurement range.

Features

• Option 02 Base Configuration: Standard 1/2-20 UNF threaded probe body with integrated protective armor.
• Option 00 Unthreaded Length: Fully threaded case body (0.0 inches unthreaded) for standard depth installation.
• Option 10 Case Length: Short 1.0-inch overall case length suitable for tight clearance envelopes.
• Option 10 Total Length: 1.0-meter (3.3 feet) integrated probe lead length.
• Option 01 Connector: Miniature coaxial ClickLoc connector with an integrated fluorosilicone connector protector.
• AISI 302 Stainless Steel Armor: Helical wrap with FEP outer jacket provides physical protection.
• 11 mm Tip Diameter: Delivers a 4.0 mm (160 mils) linear range with a standard 3.94 V/mm (100 mV/mil) incremental scale factor.

Applications

• Axial (thrust) position measurements on steam turbines and utility turbomachinery.
• Ramp differential expansion monitoring on industrial turbines.
• Rod position and rod drop measurements on reciprocating compressors.
• Shaft vibration and rotor position tracking on large fluid-film bearing rotating machines.
• Tachometer, phase reference (Keyphasor), and zero speed measurements.

Installation Guidelines

• Probe Gap Setting: Set the initial physical gap to 2.5 mm (100 mils) to center the output in the 4.0 mm linear range.
• Mounting Torque: Secure the 1/2-20 UNF probe case using the supplied lock nut. Do not exceed the maximum torque limit of 45.2 N-m (400 in-lb); recommended installation torque is 15.2 N-m (133 in-lb).
• Bend Radius: Maintain a minimum bend radius of 25.4 mm (1.0 in) along all sections of the armored FEP lead cable to prevent coaxial layer damage.
• Connector Connection: Connect the miniature coaxial ClickLoc connector to the extension cable. Ensure a finger-tight connection, not exceeding 0.565 N-m (5 in-lb) maximum torque.
• Environmental Protection: Utilize the integrated fluorosilicone connector protector to guard the connection against industrial contamination, moisture, and oils.

Compliance and Certifications

• Electromagnetic Compatibility (EMC): European Community Directive 2014/30/EU, standards EN 61000-6-2 (Industrial Immunity) and EN 61000-6-4 (Industrial Emissions).
• RoHS: European Community Directive 2011/65/EU.
• FCC: Complies with Part 15 of FCC Rules.
