Pyrocil Metal Sheathed Industrial Thermocouples

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 mulllite 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 manufactures 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.
