It is intended for measurements that benefit from the 3300 XL 11 mm system’s longer 4.0 mm linear range, including axial position, differential expansion and rod-position work. Target size and available mounting space must also suit the larger probe system.

It has an unarmored M16 x 1.5 case with zero unthreaded length, a 50 mm overall case and a 1.0 m integral lead. The standard miniature ClickLoc connector is supplied without a connector protector.

Not on thread size alone. This model belongs to the 3300 XL 11 mm measurement system and must be matched with the correct extension cable and Proximitor Sensor; an 8 mm or legacy 7200 component changes the calibrated system response.

The published matched-system values include a 4.0 mm linear range, a nominal 3.94 V/mm scale factor and frequency response from 0 to 8 kHz. These values apply to the complete 11 mm chain rather than the probe by itself.

The published recommendations call for a minimum 30.5 mm diameter flat target and a minimum 152 mm shaft diameter for the stated performance. The mechanical design should also provide the required 2.5 mm nominal gap and movement travel.

The probe, extension cable and Proximitor Sensor are calibrated as one system, so mixing families or total lengths can change sensitivity and usable range. Keeping every chain part in the 11 mm configuration protects the intended scale and linearity.
