Description

A kind of device of measurement thermocouple time constant
Technical field
This utility model is related to temperature sensor time constant fields of measurement, more particularly to a kind of measurement thermocouple time is normal Several devices.
Background technology
In industrial circle, temperature is a highly important parameter.As thermocouple has, assembling is simple, performance is steady The advantages of fixed, wide temperature-measuring range and fast response time so which becomes widely used temperature transducer in multiple fields.Survey The time constant of calorimetric galvanic couple is significant for the thermocouple for requiring fast response time, and its time constant is detection thermoelectricity The important indicator of even dynamic test performance.The size of thermocouple time constant and the physical parameter of thermocouple, geometric parameter and The physical factors such as the operating mode of measurement temperature are relevant, and the factor of influence time constant has much and thermometric environment is more multiple to which It is miscellaneous, it is difficult to try to achieve correct time constant with simple theoretical model, all it is experimentally in actual measurement obtaining. Therefore, the mode for studying wide accommodation and energy fast and accurate measurement thermocouple time constant is significant.
