Flat-surface contact sensor reduces error

By Control Engineering Staff March 7, 2001

St. Louis, Mo. -True Surface Thermocouple (TST) is a small-profile contact sensor intended for measuring flat-surface temperature in multiple locations. It reduces temperature-sensing errors associated with ambient airflow and includes an isothermal-measuring junction for 1/8th the error of common ‘washer’ style thermocouples. A molded insulator protects the isothermal measuring block from ambient flow. TST is rated to 392 °F. Watlow www.watlow.com
