Where they are used
-
The industrial metal sheathed Type K thermocouples are available by special order.
-
They are not as long-lasting as our standard 8 gauge thermocouple when it is protected by the industrial mullite protection tube.
-
However, they do offer greater sensitivity to temperature change and so may be appropriate in applications that are below about 2200°F and require sensitivity (glass is a good example).
Technical details
-
L&L provides these thermocouples with a 1/4” diameter sheath. These will last longer than the smaller 1/8” diameter thermocouples that some manufacturers use. We use a high-quality ceramic terminal block on the end. They are 6-1/2" long.
-
From our own extensive testing, we found that this particular metal sheathing performed best of the available materials on the market under repeated Cone 10 firings.
