The 93 series are a variation of the 92 series where these are the ATEX and IECEx approved spring loaded stainless steel nipple assemblies. This assembly can also be used with any approved equipment or transmitter that offers at least the same level of protection.This thus allows the entire assembly to be ATEX and IECEx approved.

The assembly has a 1/2" NPT thread at the probe end and a 1/2" NPT or M20 thread at the lead end. The probe end of the nipple union is threaded to accommodate an optional protection of the probe such as a thermowell.

The above description encapsulates the entire product series. Specifications for individual configurations may vary depending on the selection chosen.
