330877-040-37-05

Features:

• Interface Between the 50 mm Probe and 3300 XL 50 mm Proximitor Sensor
• Combines Capability of High-Temperature Signal Transmission with FluidLoc Armor Protection
• Operates in Conjunction with the 3300 XL 50 mm Probe and 3300 XL 50 mm Proximitor Sensor

The 330877-040-37-05 operates as the 3300 XL 50 mm Extension Cable in a 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 over its 4.0 meters (13.1 feet) cable length and transmits accurate displacement measurements through the system to support steady state operation of differential expansion (DE) or rotor expansion (RX) monitoring in large steam turbine generators. Seamless signal transmission is standard with the 330877-040-37-05, and using this extension cable with the FluidLoc armor option ensures robust protection against harsh environmental conditions in the event of high-temperature steam turbine DE environments. The 330877-040-37-05 has made improvements in several areas over previous extension cable designs in addition to incorporating High Temperature FluidLoc cable construction and special high-temperature ClickLoc connectors within the 3300 XL 50 mm system.

The 330877-040-37-05 provides essential connection functions critical to the entire transducer system, and is a vital component of the measurement path, directly affecting the proper, normal operation of the overall monitoring system for differential expansion measurement. One 330877-040-37-05 extension cable is required per 50 mm probe installation to complete the connection to the Proximitor Sensor. The 330877-040-37-05 features multiple agency approvals confirming compliance with stringent industry standards and is always utilized with the FluidLoc armor option for enhanced protection in demanding industrial environments.

For Dual Redundant Measurement applications, the 3300 XL 50 mm Transducer System requires a second 330877-040-37-05 extension cable connected to a complementary probe observing the opposite side of the differential expansion collar. In addition to standard single transducer operation, the redundant configuration also performs complementary input measurement effectively doubling the measurable DE range. The 330877-040-37-05 dual measurement configuration executes accurate displacement sensing using the extended linear range specified in the 3300 XL 50 mm transducer system options. Using this method, the redundant measurement system continually monitors the differential expansion between the turbine rotor and machine stator. If the system detects that the primary measurement path requires extended range coverage up to 56 mm (2.2 inches), it will automatically utilize the complementary 330877-040-37-05 connected probe and place the expanded measurement data in the system monitoring records.
