Fiber Glass Insulated Twisted Thermocouple Wire



FIBER GLASS INSULATION is ideal for general application requiring moderate abrasion, moisture resistance & high temperature resistance up to 500 °C. Fiber Glass are closely & tightly braided over the thermocouple conductors and pair twisted. It is widely used in consumable application especially used in sensor manufacturing & heat treatment applications and has a superior performance in high abrasive elements.

Cable for Type of THERMOCOUPLE GRADE CALIBRATION: T, J, K, E, N

Thermal Accuracy conforms to AMERICAN Limits of Error ASTM E 230 – ANSI MC 96.1 & IEC Thermal Tolerance Class EN 60584 – 2.
