Other details:

       Sheathed thermocouple cable materials are extremely important for the manufacture of sheath thermocouple. They are  firm assemblies which are being manufactured by a combined processing of the coupling wire or pure nickel wire or filigrees, organic mineral insulant, metal sleeve. It is  widely applicable for the industrial departments and sic-tech fields in all trades and professions.Our sheathed cable company is one of the largest manufacturers in Shanghai, China. It may furnish various models & specifications materials.   

Features:

        Small external diameter, quick heat response, may be bent, long lifetime, fine air-tightness, wide thermometric scope, high voltage resistant, anti-vibration, narrow mounting pipeline, may be used under bending conditions.
