330877-040-36-05

Features:

• Interface Between the 3300 XL 50 mm Probe and 3300 XL 50 mm Proximitor Sensor
• Combines High-Temperature Signal Transmission with FluidLoc Cable Protection
• Operates in Conjunction with the 3300 XL 50 mm Transducer System and Large Steam Turbine Generators

The 330877-040-36-05 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 Proximitor Sensor. It continuously maintains signal integrity over its 4.0 meters (13.1 feet) cable length with FluidLoc cable armor and withstands continuous temperatures up to 200°C (392°F) and intermittent exposure up to 250°C (482°F) to support steady state operation of differential expansion and rotor expansion measurements. Seamless signal transfer is standard with the 330877-040-36-05, however using proper ClickLoc connector installation with connector protectors will ensure contamination-free connections in harsh steam turbine environments. The 330877-040-36-05 incorporates multiple agency approvals and special high-temperature ClickLoc connectors within the 3300 XL transducer line.

The 330877-040-36-05 provides essential signal transmission functions common to the entire transducer system, and is a critical component of the measurement path, directly affecting the accurate, reliable operation of the overall monitoring system. One 330877-040-36-05 extension cable is required per probe installation depending on the distance between the probe mounting location and the Proximitor Sensor. The 330877-040-36-05 features removable collar ClickLoc connectors on the probe lead and is always utilized with connector protectors and a disposable connector protector installation tool to facilitate routing through tight clearances.

For complementary input transducer applications, the 3300 XL 50 mm System requires a second 330877-040-36-05 extension cable or equivalent to connect the complementary probe installed on the opposite side of the differential expansion collar. In addition to standard single probe observation, the complementary configuration also performs extended range measurement. The 3300 XL 50 mm dual transducer configuration executes differential expansion measurement using the long linear range specified in the transducer system specifications. Using this method, the measurement system continually monitors the differential expansion across both sides of the collar. If the system detects that the primary transducer is no longer providing stable measurement (outside the 27.9 mm (1100 mils) linear range or due to target obstruction), it will automatically rely on the complementary transducer and maintain continuous monitoring of rotor-to-stator growth differential.
