Bently Nevada 330877-040-37-00 3300 XL 50 mm Extension Cable

Description

Option 040 (4.0 m cable length) and Option 37 (FluidLoc extension cable with stainless steel armor) specify the configuration for this 330877-040-37-00 3300 XL 50 mm extension cable. This cable connects a 330876 50 mm proximity probe to a 330878 Proximitor sensor, preserving signal integrity for eddy-current displacement measurements on large rotating machinery. The FluidLoc coaxial construction prevents moisture ingress through the cable structure, while the flexible stainless steel armor provides mechanical protection against physical abrasion, cutting, and severe environmental exposure.

Unlike the unarmored option (Option 36), the armored jacket (Option 37) includes a flexible stainless steel conduit with a protective perfluoroalkoxyethylene (PFA) outer sleeve. Because this specific variant uses Option 00, it is not certified for hazardous area installations, serving as a direct replacement in general industrial locations.

Features

• Option 040 cable length provides exactly 4.0 meters (13.1 feet) of extension length.
• Option 37 configuration includes flexible stainless steel armor with a protective PFA jacket over the FluidLoc coaxial cable.
• Option 00 specifies a non-certified configuration without hazardous area agency approvals.
• FluidLoc coaxial cable technology prevents oil, water, or steam from migrating through the internal cable core.
• ClickLoc gold-plated brass connectors provide positive mating and high vibration resistance.
• Operating temperature limit of -51 degC to +200 degC (-60 degF to +392 degF) ensures stable operation under severe thermal conditions.

Applications

• Axial position and radial vibration monitoring on large steam or gas turbine rotors.
• Differential expansion (DE) and complementary input differential expansion (CIDE) measurement systems.
• Large industrial rotating machinery with oversized shaft targets requiring a 50 mm sensor system.
• Power plant generators, heavy process compressors, and large industrial fans operating in high-temperature environments.

Installation Guidelines

• Verify that the combined length of the connected 330876 proximity probe and the 330877 extension cable precisely equals the designated 5.0-meter or 9.0-meter system length of the target 330878 Proximitor Sensor.
• Ensure the minimum bend radius of 25.4 mm (1.0 in) is not violated at any point along the armored cable routing.
• Tighten ClickLoc coaxial connections only by hand (finger tight) or up to a maximum torque of 0.565 N-m (5 in-lb). Avoid tools that can damage the gold plating.
• Install the supplied male and female connector protectors over the mated coaxial junction to prevent mechanical damage and oil/moisture contamination.

Compliance and Certifications

• Option 00 designates a general-purpose electrical classification with no hazardous area agency approvals.
• Complies with the European CE mark requirements.
