The Style MTA4 is a mineral insulated (MI) cable thermocouple assembly with a stripped cold end, designed for temperature sensing in harsh environments. It features a 1/2-inch stripped and resin-sealed junction to inhibit moisture penetration. Available in Type J with 316 stainless steel sheath and Type K with Alloy 600 sheath, it supports diameters of 0.063", 0.125", 0.188", and 0.250", and standard lengths of 7", 13", 19", and 25". Junction types include exposed (E), grounded (G), and ungrounded (U), with options for compression fittings and custom lengths. The sheath is fully annealed for formability around a mandrel four times the sheath diameter and is rated for continuous operation up to 2150°F (1177°C) for Alloy 600 and 1650°F (899°C) for 316 stainless steel.
