| Exact reference | 330851-04-00-27-10-01-00 |
| Product family | 3300 XL 25 mm Proximity Probe |
| Primary measurement | Differential expansion and displacement in steam-turbine TSI systems |
| System scale factor | 0.787 V/mm (20 mV/mil) nominal |
| Linear range | 12.7 mm (500 mils), approximately 0.63 to 13.33 mm from target |
The 3300 XL 25 mm system measures differential expansion on mid-size to large steam turbine generators. Its extended range tracks the difference in growth between the turbine rotor and the machine casing, supporting collar or ramp measurement arrangements within turbine supervisory instrumentation.
| 01 | Confirm the target. Verify target material, diameter, collar or ramp geometry and expected axial travel. |
| 02 | Match the loop. Use the correct 25 mm extension cable and Proximitor Sensor system length. |
| 03 | Protect the connector. Keep ClickLoc interfaces clean and use the specified connector protectors. |
| 04 | Verify motion. Simulate collar movement and confirm the complete linear travel after installation and periodically in service. |
Use this reference where a smooth 1.06 in side-exit case, 2.7 in case length, 1 m lead and stainless-steel armor match the mechanical installation. Typical duty is steam-turbine differential expansion using collar or ramp targets. Confirm the exact mounting method, target and complete loop before ordering.
Is 330851-04-00-27-10-01-00 a complete system?
No. It is the probe reference; the extension cable and 3300 XL 25 mm Proximitor Sensor are selected separately.
Can a previous 7200 system component remain in the loop?
For an upgrade, the probe, extension cable and Proximitor Sensor must all be replaced with 3300 XL 25 mm components.
