Option 02 (M30x2 metric thread), Option 000 (0 mm unthreaded length), and Option 030 (30 mm overall case length) specify this 3300 XL 25 mm proximity probe configuration — 330851-02-000-030-10-00-05. This eddy-current non-contact sensor is used for measuring differential expansion (DE) on steam turbine generators. Operating as part of the 3300 XL 25 mm transducer system, it measures rotor axial growth relative to the machine casing.
Unlike other case options with English threads or smooth bodies, this probe features an M30x2 metric threaded case (Option 02) with a short 30 mm case length (Option 030). It includes a 1.0 m lead cable with an unarmored PFA jacket (Option 00) and carries multiple agency approvals (Option 05) for hazardous locations.

| Manufacturer | Bently Nevada |
| Part Number | 330851-02-000-030-10-00-05 |
| Product Type | 3300 XL 25 mm Proximity Probe |
| Probe Diameter / Tip | 25 mm |
| Linear Range | 12.7 mm (500 mils) |
| Range Limits | Begins at approximately 0.63 mm (25 mils) from target and extends to 13.33 mm (525 mils) |
| Output Voltage Range | Approximately -1.5 Vdc to -11.5 Vdc |
| Average Scale Factor (ASF) | 0.787 V/mm (20 mV/mil) nominal |
| Deviation from Best Fit Straight Line (DSL) | Less than +/-0.31 mm (+/-12 mils) |
| Frequency Response | 0 to 2.7 kHz (+0, -3 dB typical with up to 305 m of field wiring) |
| Recommended Minimum Target Size | 61 mm (2.4 in) diameter (flat target) |
| Probe Tip Material | Polyetheretherketone (PEEK) |
| Probe Case Material | AISI 304 stainless steel (SST) |
| Probe Cable Type | 75 ohm triaxial, perfluoroalkoxyethylene (PFA) insulated FluidLoc probe cable |
| Connector Material | Gold-plated brass and gold-plated beryllium copper |
| Operating and Storage Temperature | -35 degC to +200 degC (-31 degF to +392 degF) |
| Short Term Temperature Tolerance | +250 degC (482 degF) maximum for less than 24 hours |
| Relative Humidity | 100% condensing, non-submersible (when connectors are protected) |
| Pressure Sealing | Designed to seal differential pressure between tip and case (Viton O-ring and compression seal) |
| Probe Weight (typical) | 230 g (8.1 oz) (minimum length case, 1m lead, no armor) |
Proper installation requires correct probe gapping and cable routing. The linear range of the 25 mm system begins at approximately 0.63 mm (25 mils) from the target surface. Secure the probe using the supplied locknut with predrilled safety wire holes. Torque the M30x2 threaded case to the recommended torque of 68 N-m (50 ft-lb). Ensure that the connectors are kept dry and protected using connector protectors. Avoid exposing the cable to sharp bends; observe a minimum bend radius of 25.4 mm (1.0 in).
This probe complies with European CE markings and is approved for hazardous environments under option 05 (Multiple Approvals). This includes Class I, Zone 0, AEx/Ex ia IIC T5...T1 Ga intrinsically safe installations when used with approved Zener barriers or galvanic isolators, as well as Division 2 non-incendive classifications.
