Sonde de proximité Bently Nevada 330851-06-000-070-10-00-05 3300 XL 25 mm

Description

Option 06 (M39x1.5 metric thread), Option 000 (0 mm unthreaded length), and Option 070 (70 mm case length) specify the physical build of the 330851-06-000-070-10-00-05, a 3300 XL 25 mm proximity probe engineered for large-target differential expansion and axial displacement measurements.

Unlike standard-profile probe variants utilizing smaller English threads (such as the 1-1/2-12 thread under Option 01) or standard metric threads (like the M30x2 thread under Option 02), this configuration employs a robust M39x1.5 metric thread with a 45 mm lock nut and 36 mm wrench flats. Furthermore, this probe is supplied with a 1.0-meter non-armored FluidLoc triaxial cable (Option 10 and Option 00) and carries multiple hazardous area agency approvals (Option 05) for compatibility with critical machinery protection systems.

Features

• Option 06 case style provides a metric M39x1.5 thread, supplied with a 45 mm lock nut and 36 mm wrench flats.
• Option 000 indicates a fully threaded case length with 0 mm of unthreaded length.
• Option 070 provides a 70 mm overall case length for precise positioning in machinery housings.
• Option 10 supplies a 1.0-meter (3.3 feet) FluidLoc triaxial probe cable with PFA insulation.
• Option 00 specifies a non-armored cable configuration for standard conduit routing.
• Option 05 offers multiple international hazardous area certifications including CSA, ATEX, and IECEx.
• PEEK (polyetheretherketone) probe tip provides robust chemical resistance and electrical isolation.
• AISI 304 stainless steel case material delivers long-term corrosion resistance.
• Miniature male coaxial connector provides secure, low-loss connections to the extension cable.

Applications

Typical applications include:

• Steam turbine differential expansion (DE) monitoring on mid-size to large power generation units.
• Non-contact axial shaft displacement and shaft position monitoring.
• Rotor position and thrust bearing wear measurement on heavy industrial machinery.
• Large-target displacement measurements requiring extended linear range (12.7 mm).

Installation Guidelines

To establish safe and proper transducer operation, observe these mounting guidelines:

• Target Size: Ensure the target flat surface is at least 61 mm (2.4 in) in diameter. Smaller target dimensions can restrict the linear range.
• Torque Limits: Tighten the probe case to a recommended torque of 68 N-m (50 ft-lb). Do not exceed the maximum rated limit of 163 N-m (120 ft-lb). Always utilize the supplied 45 mm lock nut.
• Cable Protection: Seal all connector joints using silicone self-fusing tape to protect connections from moisture and oil contamination.
• Bend Radius: Avoid tight routing of the FluidLoc coaxial cable; preserve a minimum bend radius of 25.4 mm (1.0 in).
• System Length Match: Pair the 1.0-meter probe cable with a complementary extension cable to reach exactly 5.0 m or 9.0 m, matching the Proximitor Sensor's designed system length.

Compliance and Certifications

This transducer is approved under multiple hazardous area certification packages (Option 05), including:
