INSULATED
Hot junction insulated from sheath. Gives floating output with typical insulation resistance in excess of 100 megohms

GROUNDED
Hot junction welded to sheath tip giving earthed output and faster response to temperature changes

EXPOSED
Fastest response mainly for the measurement of air temperature in ducts. Restricted to a maximum operating temperature of 570°F
