Description
The Bently Nevada 24765-02-00 is a case expansion transducer assembly used in the Bently Nevada machinery protection system. Here’s a breakdown of its function and key features:
Function:
- The 24765-02-00 transducer assembly monitors the case expansion of a machine. Case expansion refers to the thermal growth of the machine casing as it expands during startup and operation.
- By measuring this expansion, the transducer helps identify potential issues like:
- Misalignment between the machine shaft and bearings.
- Looseness in the machine foundation.
- Excessive thermal growth that can cause rubbing between rotating and stationary parts.
- Early detection of these issues allows for preventive maintenance and avoids costly downtime or equipment damage.
Key Features:
- Linear Variable Differential Transformer (LVDT): The transducer assembly likely uses an LVDT to convert the linear displacement of the machine casing due to thermal growth into an electrical signal.
- Weatherproof Enclosure: The assembly is housed in a weatherproof enclosure, making it suitable for harsh industrial environments.
- User-selectable Linear Range: The “02” in the part number (24765-02-00) might indicate a linear range of 0.8 millimeters (2.0 inches) for displacement measurement. However, the specific range may vary depending on the model variant.
- Spring Option: The “-00” in the part number likely signifies the absence of a spring return mechanism. The transducer might rely on the machine’s own forces to maintain contact with the casing.
Applications:
The Bently Nevada 24765-02-00 is used in various industrial applications where monitoring thermal growth and maintaining proper machine alignment is crucial, such as:
- Steam Turbines: Monitoring case expansion in steam turbines to ensure proper shaft alignment and prevent rubbing between components.
- Gas Turbines: Similar to steam turbines, monitoring case expansion helps maintain alignment and prevent rubbing in gas turbines.
- Large Rotating Equipment: The transducer can be used in other applications with large rotating machinery, such as generators, compressors,
