The retrievable probe is widely used in the oil and gas production and transmission industry and is part
of a specially designed retrievable system. The probe is carried on a specially designed plug and in-
serted through a welded or flanged access fitting as shown in Figure 12.
The retrievable probe, which is normally constructed in AISI 316L stainless steel, can be inserted and
removed from systems operating up to 3600 psi without system shutdown. This is achieved by using a
portable valve and retrieval tool that can be moved from probe location to probe location as insertion or
removal is required.
