Application & Failure Scenarios
Turbine Differential Expansion
During turbine startup, shutdown and changing operating conditions, the rotor and casing may expand at different rates. Differential-expansion monitoring measures their relative movement to help operators assess machine movement against operating limits.
Check the measurement path, including probe condition, extension-cable connections, sensor power, field wiring and monitor input. Also consider target condition, installation gap and system compatibility.
Confirm the full part number, probe and extension-cable arrangement, electrical length, mounting requirements and applicable approvals. Similar housing or connectors do not establish interchangeability.
Technical Specifications
Published system-level characteristics for the 3300 XL 25 mm proximity transducer system. Values depend on test conditions and component configuration.
Published system performance is based on specified target material, target size, probe gap, load and component temperatures. Calibration to another target material may affect accuracy and interchangeability. Confirm the installed configuration before using these values for engineering decisions.
How the Measurement Channel Works
Responds to changes in the gap between the probe tip and conductive target. Correct installation geometry is essential.
Must match the probe and sensor arrangement. A mismatch can change the electrical characteristics of the channel.
Works with the matched probe and extension cable to provide a signal for the monitoring equipment.
Monitor configuration, wiring and alarm settings matter when a signal disagrees with expected machine movement.
Installation & Troubleshooting Checklist BEFORE COMMISSIONING · Select to expand
Verify the probe, extension cable and Proximitor Sensor are intended to operate together as a compatible 3300 XL 25 mm system.
Check installation gap, target surface and alignment against the requirements of the installed measurement arrangement.
Inspect connector condition, contamination, cable routing, shielding and wiring termination. Avoid bending the cable below the specified minimum bend radius.
Verify sensor supply, barrier arrangement where applicable, field wiring and monitor input settings before replacing a component.
Confirm the selected configuration is suitable for the installation area and required mounting method.
330850-51-00 Datasheet / Manual
For technical evaluation, check the 3300 XL 25 mm Proximity Transducer System specifications for measurement range, electrical requirements, operating environment and component compatibility. Confirm the exact order code and approval requirements against the installed unit before ordering.
Frequently Asked Questions
