Thermocouple is commonly used in low temperature zone of a kind of temperature measuring element. Thermocouple resistance using material when the temperature changes itself along with the change of characteristics to measure temperature. Thermocouple heated parts ( Thermal element) Is uniform with fine wire wrapped around the insulation materials on the skeleton of measured medium in the presence of temperature gradient, temperature is measured by thermal element is located within the scope of average temperature in the medium layer. Main features: high measuring accuracy, stable performance. The platinum thermocouple measurement accuracy is high. The structure characteristics of the thermocouple, thermocouple and usually display meter, recording meter and electronic regulator. It can be directly measured from various production process 200 ℃ to + 600 ℃ within the scope of the liquid, steam and gas medium and the temperature of the solid surface. WZ thermocouple assembly: usually by the temperature sensing element, main parts, such as installing fixtures and connection box with high measuring accuracy, stable and reliable performance, etc. In the practical application to pt100 platinum thermocouple is widely used. WZPK platinum thermocouple, thermocouple is by the thermal components, wire, insulation materials, stainless steel casing combination solid body. Thermocouple advantages: slender shape, heat fast response time, vibration resistance, long service life, etc.
