This assembly is particularly suited to measuring temperature of asphalt and other granular materials such as grain, sand, gravel, and pulverized coal. The element is solid 14 gauge with porcelain insulation inside a 1/4” NPT seamless steel case hardened protection pipe. The end of the pipe is cut at an angle to protect the element and allow close contact with the material. The tip of the thermocouple with grounded junction style is welded to the end of the pipe for greater sensitivity.
