Temperature sensor temperature response lag compensation method

Abstract

The invention discloses a temperature sensor temperature response lag compensation method. Through establishing a prediction compensation model, a compensation parameter is calculated, a problem of measurement lag existing in a temperature sensor can be well overcome, knowing details of a system model parameter of the sensor is not needed, a temperature lag problem is solved, a problem of difficulty in predicting the boiling time caused by high-temperature-segment temperature lag existing in electric kettle design can be solved, a selection scope of the temperature sensor is expanded, and particular adjustment on a detection point of the temperature sensor is not needed.

Description

technical field [0001] The invention relates to the technology in the field of temperature sensors, in particular to a temperature response hysteresis compensation method for a temperature sensor. Background technique [0002] Since the commonly used temperature sensors are thermocouples and thermal resistances, there are generally protective sleeves. In the temperature measurement process, it is necessary to establish a thermal balance with the measured medium to sense the temperature change, the response time is too long, and there is a serious hysteresis in temperature measurement. For example, in the application of kettle temperature measurement, the temperature lag leads to inaccurate control of the high temperature period. One of the existing solutions is to select a sensor with a small time constant; but to select the position of the detection point according to actual needs. But none of these methods can fundamentally solve the problem. Contents of the invention ...
