Thermocouple thermal response time long specific reason is what? Release date: 2019 04 - 08 viewed: zero

In industrial production, temperature is one of the important parameters need to measure and control. Widely used in the temperature measurement, thermocouple, it has a simple structure, easy fabrication, wide measuring range, high precision, inertia small, easy in output signal transmission. In addition, since the k type thermocouple is active sensors, so there is no need to measure the external power supply. It is very convenient to use, so usually used to measure the temperature of the furnace gas or liquid, the surface temperature of the tube and solid. First of all, the response time of the thermocouple to the structure and size. That is to say, the thicker the hot electrode and the diameter of the protecting tube, tube wall is thick, the greater the inertia, so the stability of thermocouple, the longer the greater its effect on response time. Second, thermocouple response time also changes according to the working state, that is to say, the same structure of the thermocouple, under the condition of different heat exchange, response time is different. Third, the thermocouple made of different materials with different thermal conductivity. Metal protection tube, for example, has better than ceramic protection tube of the thermal conductivity, thermal inertia is small, therefore, thermocouple stable in a short period of time, the response time is short. Beijing instrument huashi network technology co. , LTD. Is a company specializing in the production of thermocouples, K type thermocouple, S type thermocouple, thermocouple, wear-resisting armoured thermocouple, heat resistance, pressure transmission, compensation conductor, bimetallic thermometer instrument manufacturers, instrument in huashi products of high precision, long life, quality assured, etc, and provide product customization service, look forward to your inquire: 010 - 67615826
