What Is A Grounded Junction?
Grounded junctions are a type of thermocouple measuring junction. A grounded junction is formed by the two thermocouple conductors being welded together with the external sheath. This forms a completely sealed junction. As the thermocouple conductors are touching the outer sheath the thermocouple is not electrically insulated and may be affected by stray EMF’s. The junction is more robust than an exposed junction and is somewhere in between exposed and insulated junctions in response time.
