Single (PG) and Multiple (MHM and MHC) Feedthroughs :

The PG, MHM and MHC series of feedthroughs were designed to produce a leak free method of passing a single probe (PG) or multiple probes or conductors (MHM and MHC) from ambient through to process conditions.

The bodies of these feedthroughs are machined from 316L stainless steel and leak prevention is based upon soft sealant technology using Teflon®. Various thread forms and process connections are available including NPT, BSP, weld-neck and Tri-clover hygienic flanges.

Applying the correct torque to the gland cap nut will ensure a permanent leak free seal without damage to the probe or conductor. Following the removal of a probe or probes for calibration the sealant can be re-used.

Where it is necessary to remove one or more probes (perhaps for operational reasons) when using multiple probes, normal sterilising procedures can still be maintained by fitting the vacant positions with an EGB. This is fabricated in 316L stainless steel to the same diameter of the absent probe. It is constructed with a larger diameter on the chamber side to prevent movement of the blank through the sealant when exposed to chamber pressure.
