Thermocouple Hot Junctions

Thermocouple hot junction styles

	The thermocouple junction is fully insulated from the welded sheath end. The ungrounded junction is excellent for applications where stray EMF’s can affect the reading and for frequent or rapid temperature cycling. Response time is longer than for a grounded junction.
	The sheath and conductors are welded together, forming a completely sealed integral junction. Recommended in the presence of liquids, moisture, gas or high pressure. The wire is protected from corrosive or erosive conditions. Response time with this style approaches that of the exposed junction.
	Two separate thermocouples are encased in a single sheath. The isolation would prevent ground loop errors if wired to separate instruments. Available with grounded or ungrounded junction.
	Thermocouple wires are welded to form a junction. Mineral insulated cable is sealed against liquid or gas penetration. This junction style provides the fastest possible response time but leaves the thermocouple wires unprotected against corrosive or mechanical damage.
	Swaged thermocouple tip for fast response and sturdy probe design sealed against liquid or gas penetration. This junction style provides fast response time and at the same time a fully insulated and protected hot junction.
