This eddy-current probe is equipped with a 1.0 m (3.3 ft) integrated cable encased in flexible AISI 302 stainless steel armor with a PFA outer jacket (Option 01). Designed without threaded mounting, the 1.06-inch smooth cylindrical case is ideal for clamp-style mounting configurations, while the side-exit cable arrangement resolves clearance constraints in narrow machine enclosures where axial rear-exit cables cannot be routed without exceeding the minimum bend radius.\u003c\/p\u003e\n\n\u003cp\u003eThis configuration features a 3.0-inch overall case length (Option 030) and contains no unthreaded length (Option 000) as typical for smooth-case probes. It is manufactured without agency approvals (Option 00), making it suitable for general industrial environments or areas that do not require hazardous area certifications. The \u003cstrong\u003e330851-04-000-030-10-01-00\u003c\/strong\u003e proximity probe operates within a 3300 XL 25 mm transducer system, combining with a 330854 extension cable and a 330850 Proximitor sensor to measure axial shaft position, differential expansion, or rod-drop in reciprocating compressors and steam turbines.\u003c\/p\u003e\n\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n

standard transducer clamp (such as Bently Nevada part 29660-01) surrounding the smooth 1.06 in casing. The side-exit cable requires a minimum of 25.4 mm (1.0 in) bend radius during routing to prevent strain on the internal triaxial conductors. Ensure that the combined length of the probe cable (1.0 m) and the extension cable equals the total system length expected by the Proximitor sensor (typically 5.0 m or 9.0 m). Connector-to-connector torque must be finger tight, and can be tightened to a maximum of 0.565 N-m (5 in-lb) using proper tools. Use silicone self-fusing tape or connector protectors (such as 40180-02) for environments where moisture or contaminants are present.\u003c\/p\u003e\n\n\u003ch3\u003eCompliance and Certifications\u003c\/h3\u003e\n\u003cp\u003eThis standard configuration complies with the European CE mark requirements.
