Thermometers
Thermocouple (Resistance) for Petrochemical Industry

application

)专业针对石油化工部门设计,可以直接测量-200℃~1600℃范围内液体、蒸汽和气体介质以及固体表面测温。 The thermocouple (resistance ) for petrochemical industry is specially designed for the petrochemical sector. It can directly measure the temperature of liquid, steam and gas medium and solid surface in the range of -200 ℃ ~ 1600 ℃. zzyfwh.com
working principle
The electrode of a thermocouple consists of two different conductor materials. When there is a temperature difference between the measuring end and the reference end, thermoelectric potential will be generated, and the working instrument will display the temperature value corresponding to the thermoelectric potential.
Thermocouples use the property that the material's own thermocouple also changes with temperature to measure temperature. The heated part of the thermocouple (temperature sensing element) is evenly wound on a skeleton made of insulating material with thin metal wires. When a temperature gradient exists in the measured medium, the measured temperature is the range of the temperature sensing element The average temperature in the inner dielectric layer.

主要技术参数 Main technical parameters of thermocouple (resistance) for petrochemical industry

EC1515IEC584IEC751JB / T5518-91JB-T5582-91

Generally refers to the static outer diameter of the protective tube without breaking at normal temperature. The allowable working pressure is not only related to the material, diameter, and wall thickness of the protective tube, but also to the structure and the flow rate and type of the measured medium for the installation method.
