Overview Manuals Specifications

Features:

  • FluidLoc extension cable with armor protection for 3300 XL 50 mm proximity transducer systems
  • High-temperature ClickLoc connectors designed for reliable performance in extreme thermal environments
  • Engineered specifically for steam turbine differential expansion and rotor expansion monitoring applications
The 330877-080-37-00 provides essential signal connection functions critical to the entire monitoring path, serving as the vital link between the sensing probe and the signal conditioning electronics, directly affecting the proper, normal operation of the overall turbine protection system. One 330877-080-37-00 extension cable is required per measurement point, connecting the 50 mm probe mounted on the turbine casing to the remotely located Proximitor sensor.

For applications requiring extended reach between the probe and Proximitor, the 330877-080-37-00 provides 8.0 meters of cable length with high-temperature ClickLoc connectors at both ends. In addition to standard signal transmission, the FluidLoc cable construction performs continuous moisture barrier protection. The 330877-080-37-00's design incorporates front and rear probe seals in the complete system that work together with the FluidLoc cable to prevent moisture from entering the probe tip.

The 330877-080-37-00's robust construction ensures reliable operation in demanding steam turbine environments. Using specialized high-temperature materials, the cable and connectors maintain their mechanical and electrical properties at continuous temperatures up to 200°C and intermittent exposures to 250°C. The armored jacket of the 330877-080-37-00 provides protection against physical abuse during installation and operation.

The 330877-080-37-00 Bently Nevada Extension Cable may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

Description
The Model 330877-080-37-00 is a specialized 8.0 meter extension cable engineered as an integral component of the 3300 XL 50 mm Proximity Transducer System for large steam turbine monitoring applications. This cable is specifically designed to connect the 50 mm probe to the Proximitor sensor in differential expansion (DE) and rotor expansion (RX) measurement installations.

High-temperature capability is a defining characteristic of the 330877-080-37-00, designed to survive the most demanding steam turbine DE environments. This extension cable can continuously operate and maintain its accuracy at temperatures up to 200°C (392°F), and can withstand intermittent high-temperature exposure up to 250°C (482°F).

The 330877-080-37-00 works in concert with the 50 mm probe and Proximitor sensor to deliver the longest linear range available in Bently Nevada's eddy current transducer product line. When paired with the large diameter coil of the 50 mm probe, this system achieves a maximum linear range of 27.9 mm (1100 mils), making it ideal for measuring the significant thermal expansion that occurs in large steam turbine generators.

System reliability is enhanced by the robust construction of the 330877-080-37-00. The armored FluidLoc cable provides mechanical protection against abrasion and crushing during installation and operation within turbine casings. While this model carries no specific agency approvals, the 330877-080-37-00 meets the rigorous quality standards expected for critical turbine monitoring applications.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
What is the length and primary application of the 330877-080-37-00 extension cable?
The 330877-080-37-00 is an 8.0 meter (26.2 feet) extension cable designed for the 3300 XL 50 mm Proximity Transducer System. It is specifically engineered for differential expansion (DE) and rotor expansion (RX) measurements on large steam turbine generators, where the significant thermal growth differences between the turbine rotor and stator casing must be accurately monitored.
What temperature ratings and environmental protections does the 330877-080-37-00 offer?
The 330877-080-37-00 is designed to survive the harshest steam turbine DE environments, with continuous operating capability up to 200°C (392°F) and intermittent tolerance up to 250°C (482°F). It features FluidLoc cable construction with armor protection and high-temperature ClickLoc connectors, while the complete system includes front and rear probe seals that combine with the FluidLoc cable to prevent moisture from entering the probe tip.
What is the linear range achieved when using the 330877-080-37-00 with the complete 50 mm system?
When the 330877-080-37-00 is used as part of the complete 3300 XL 50 mm Transducer System (including the 50 mm probe and Proximitor sensor), the system delivers a maximum linear range of 27.9 mm (1100 mils). This represents the longest linear range available in Bently Nevada's eddy current transducer line, making it ideal for measuring the large thermal expansions encountered in steam turbine applications.
What connector type is used on the 330877-080-37-00 and why is it significant?
The 330877-080-37-00 features special high-temperature ClickLoc connectors at both ends. These connectors are specifically designed to maintain secure, reliable connections even under extreme thermal conditions up to 250°C (482°F). The ClickLoc design enables tool-free installation while ensuring a positive locking mechanism that resists loosening due to turbine vibration, and the high-temperature materials maintain mechanical integrity throughout the operating temperature range.
