330877-080-36-05

Features:

• Interface Between the 50 mm Probe and 3300 XL 50 mm Proximitor Sensor
• Combines High-Temperature Cable Technology with Moisture-Resistant FluidLoc Protection
• Operates in Conjunction with the 3300 XL 50 mm Transducer System and Large Steam

Turbine Generator Monitoring Applications The 330877-080-36-05 operates as the 8.0-meter (26.2 feet) FluidLoc Extension Cable in the 3300 XL 50 mm Transducer System, providing reliable signal transmission between the 50 mm probe and the 3300 XL 50 mm Proximitor Sensor. It continuously maintains signal integrity across its extended length while withstanding continuous operating temperatures up to 200°C (392°F) and intermittent temperatures reaching 250°C (482°F). Seamless connectivity is standard with the 330877-080-36-05, with its High Temperature FluidLoc cable construction working in conjunction with probe seals to prevent moisture ingress at the probe tip. The 330877-080-36-05 has made improvements in several areas over previous extension cable designs in addition to incorporating special high-temperature ClickLoc connectors with removable collars for routing through tight clearances.

The 330877-080-36-05 provides essential interconnection functions common to the entire 3300 XL 50 mm Transducer System, and is a critical component of the differential expansion measurement path, directly affecting the proper, normal operation of overall rotor expansion monitoring on large steam turbine generators. One 330877-080-36-05 extension cable is required per probe installation, connecting the 50 mm probe to the Proximitor Sensor. The 330877-080-36-05 occupies the intermediate position in the transducer signal chain and is always installed between the probe (featuring ½-20 English threads or M14x1.5 metric threads with locknut) and the 3300 XL 50 mm Proximitor Sensor.

For complementary input transducer applications observing opposite sides of a differential expansion collar, the 3300 XL 50 mm System requires a second 330877-080-36-05 extension cable module installed with the redundant probe. In addition to standard single transducer operation, the complementary configuration also performs extended range measurement. The dual transducer configuration executes differential expansion measurement using the long linear range specified in the 330877-080-36-05 system options. Using this method, the complementary transducer system continually monitors rotor expansion across both sides of the collar. If the system detects that the measurement range exceeds 27.9 mm (1.1 inches) on a single side, it will automatically utilize the combined 56 mm (2.2 inches) total range capability and provide accurate differential expansion data for the System Event List.
