Then there’s “00”, which means no extra unthreaded case section. “04” points to a 40 mm case length, and “05” means the cable is 0.5 meter long. Not a huge detail maybe, but when installation space is limited, these measurements matter more than people expect. A probe that’s slightly off can become annoying during fitting. In some setups, the cable arrangement may also match a 3300 XL extension cable 0.5m, depending on how the monitoring loop is designed.

For standard material like AISI 4140 steel, sensitivity is around 7.87 V/mm, or 200 mV/mil if that’s the preferred unit in your project. In real applications, this helps with eddy current displacement measurement and stable machinery vibration pick-up, especially where accurate movement tracking matters. You’ll see this kind of setup fairly often inside a Bently Nevada 3500 monitoring loop or other 3300 XL 8mm sensor system arrangements.

Another thing buyers ask about quite a lot is hazardous area approval. This version, marked with option “05”, comes with Multi-Agency Hazardous Area Approvals, so applications involving hazardous area machinery monitoring are generally not a problem. It follows standards such as ATEX, IECEx, and CSA, which tends to make project compliance easier.
