A. Grounded – The bead of the thermocouple is attached to the tip of the sheath giving a faster response than ungrounded types. Exposed – The bead of the thermocouple is exposed. Recommended for air applications which need fast responses. Ungrounded – The bead of the wire is set back slightly from the tip of the sheath and physically insulated by MgO powder. Thermocouple is electronically isolated from the sheath.
