Description
Technical Field
The invention relates to the field of sensors, in particular to a system for detecting response time of a temperature sensor.
Background
A temperature sensor (temperature transducer) refers to a sensor that senses temperature and converts it into a usable output signal. The temperature sensor is the core part of the temperature measuring instrument and has a plurality of varieties. The temperature sensor can be divided into two types of contact and non-contact according to the measuring mode, and is divided into two types of thermal resistance and thermocouple according to the characteristics of sensor materials and electronic elements, and the detection part of the contact temperature sensor is in good contact with a measured object, namely the temperature sensor, so that the heat balance is achieved through conduction or convection, and the indication value of the temperature sensor can directly represent the temperature of the measured object. Generally, the measurement precision is higher. The thermometer can also measure the temperature distribution inside the object within a certain temperature measuring range. However, a large measurement error occurs in a moving body, a small target, or an object having a small heat capacity, and commonly used thermometers include a bimetal thermometer, a glass liquid thermometer, a pressure type thermometer, a resistance thermometer, a thermistor, a thermocouple, and the like, and they are widely used in industrial, agricultural, commercial, and other sectors. People also often use the thermometers in daily life, and with the wide application of low-temperature technology in the departments of national defense engineering, space technology, metallurgy, electronics, food, medicine, petrochemical industry and the like and the research of superconducting technology, the low-temperature thermometers for measuring the temperature below 120K are developed, such as low-temperature gas thermometers, vapor pressure thermometers, acoustic thermometers, paramagnetic salt thermometers, quantum thermometers, low-temperature thermal resistors, low-temperature thermocouples and the like. The low temperature thermometer requires the temperature sensing element to be small in size, high in accuracy, good in reproducibility and stability. A carburized glass thermal resistor formed by carburizing and sintering porous high silica glass is a temperature sensing element of a low-temperature thermometer, can be used for measuring the temperature within the range of 1.6-300K, and a temperature sensor needs to test the response time, but the response time test is professional, and general testers cannot operate.
