Features:

  • Interface Between the 3300 XL 25 mm Probe and 3300 XL 25 mm Proximitor Sensor
  • Combines Signal Transmission Capability with High-Temperature FluidLoc Cable Protection
  • Operates in Conjunction with the 3300 XL 25 mm Transducer System and Steam Turbine DE Monitoring Applications
The 330854-080-25-05 operates as the 8.0-meter extension cable in a 3300 XL 25 mm transducer system, providing reliable signal transmission between the probe and Proximitor Sensor. It continuously maintains signal integrity across its 8.0 metres (26.2 feet) length while withstanding operating temperatures up to 200 °C (392 °F) and intermittent temperatures up to 250 °C (482 °F). Armored high-temperature FluidLoc cable construction is standard with the 330854-080-25-05, preventing moisture ingress and ensuring survivability in harsh steam turbine environments. Seamless electrical connectivity is ensured through special high-temperature ClickLoc connectors, however using proper connector protection during installation will maintain contamination-free contacts for optimal measurement accuracy. The 330854-080-25-05 incorporates multiple agency approvals and redundant sealing features within the 3300 XL system.

The 330854-080-25-05 provides essential signal transmission functions common to the entire transducer path, and is a critical component of the differential expansion monitoring system, directly affecting the proper, normal operation of overall turbine protection. One 330854-080-25-05 extension cable is required per probe-Proximitor connection depending on the installation distance. The 330854-080-25-05 occupies the connection pathway between probe and sensor and is always integrated with the 25 mm probe case styles including 1¼-12 or 1½-12 English threads, M30x2 or M39x1.5 metric threads, or side/rear exit configurations.

For dual transducer differential expansion applications, the 3300 XL system requires proper 330854-080-25-05 cable routing to observe collars or ramps from the thrust bearing. In addition to standard single transducer measurement, redundant configurations also perform complementary observation. The differential expansion measurement executes target observation using the linear range specified in the 12.7 mm (500 mils) system specifications. Using this method, the 330854-080-25-05 continually transmits accurate position signals. If the system detects rotor axial movement beyond expected ranges, it provides precise measurement data to the monitoring system for turbine protection decisions.

The 330854-080-25-05 Bently Nevada 3300 XL 25 mm Extension Cable may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

  • Operating & Storage Temperature: Standard range of -35°C to +200°C (-31°F to +392°F).
  • Fluid Resistance: Features FluidLoc technology, which includes a perfluoroalkoxyethylene (PFA) jacket to prevent moisture or oil from wicking through the cable into the probe tip.
  • Connector Durability: Uses gold-plated ClickLoc connectors that provide a secure, vibration-resistant connection with a simple "click" and require no special tools.
  • Physical Protection: Includes stainless steel armor (Option 25) for high mechanical protection against abrasion and physical damage.
  • Differential Expansion (DE): Primarily used on mid-to-large steam turbine generators to measure the relative growth between the turbine rotor and the machine stator (casing).
  • Harsh Environments: Specifically designed for "maximum survivability" in the high-heat, high-moisture environments typical of power generation and oil & gas facilities.
  • Replacement/Upgrade: Designed to physically and electrically replace older 7200-series 25 mm and 35 mm systems without requiring monitor reconfiguration.
  • System Integration: Connects a 25 mm proximity probe to a 3300 XL Proximitor Sensor, which then provides a standardized 0.787 V/mm (20 mV/mil) output to a monitoring system.
  • Linear Range: Facilitates a broad linear measurement range of 12.7 mm (500 mils), essential for tracking the wide movements associated with turbine expansion.
  • Signal Integrity: The 75-ohm triaxial design and high RFI/EMI immunity protect the measurement signal from nearby high-frequency radio waves and electrical noise.
Description
The 3300 XL 25 mm Extension Cable, model 330854-080-25-05, features a cable length of 8.0 metres (26.2 feet) and is equipped with armored high-temperature FluidLoc cable construction. This specific configuration, 330854-080-25-05, carries multiple agency approvals, ensuring compliance with stringent industry standards for critical industrial applications.

The 330854-080-25-05 extension cable is an integral component of the 3300 XL 25 mm Transducer System, which consists of a separate 25 mm probe, the extension cable itself, and a 3300 XL 25 mm Proximitor Sensor. The system delivers a 0.787 V/mm (20 mV/mil) output, providing a linear range of 12.7 mm (500 mils). Based on this linear range, the 330854-080-25-05 and its associated system are specifically designed for measuring differential expansion (DE) on mid-size to large steam turbine generators, addressing the critical challenge of monitoring the difference in growth rates between the turbine rotor and the machine stator (casing) during thermal cycling operations.

The 330854-080-25-05 extension cable is engineered to maintain signal integrity in the harshest steam turbine DE environments. It is designed to operate continuously and maintain accuracy in high temperatures up to 200 °C (392 °F), and can withstand intermittent high temperatures up to 250 °C (482 °F). The 330854-080-25-05 incorporates special high-temperature ClickLoc connectors as standard features, ensuring reliable connections between the probe and the Proximitor Sensor. Each 330854-080-25-05 cable is provided with connector protectors and a disposable connector protector installation tool to ensure that the connectors remain free of contamination, which is essential for maintaining measurement precision in industrial settings where debris and moisture present constant threats to sensor performance.
