Expert FAQ

What is a typical application for a 5.5-inch long probe?

It is used on large diesel engines, certain turbine designs, or any equipment where the bearing or measurement point is located far inboard from the mounting surface.

Does the long case affect the probe's sensitivity or calibration?

No. The electrical and sensing characteristics are identical to standard-length probes. Only the mechanical housing length is different.

Is special tooling needed to install this long probe?

A standard deep socket or crowfoot wrench may be helpful. The key requirement is a torque wrench capable of applying the correct torque in a potentially confined space.

Can this probe be used in a high-temperature environment?

Yes, its operating temperature range is -51°C to +177°C, identical to all 3300 XL 11mm probes. The materials are rated for this range.

Why would I choose this over a standard 2.4-inch probe?

Choose this 330707-00-55-10-01-00 only if your machine design requires the probe to reach through a very deep cavity to get close to the target shaft.
