Description

Technical Field

[0001] The utility model relates to the technical field of temperature sensors, in particular to a precision temperature sensor. Background Art

[0002] A temperature sensor is a device that can sense the temperature change of the surrounding environment or medium and convert it into an available electrical signal (such as voltage, current, resistance change or digital signal) for output. These signals can then be read by instruments, controllers or computer systems and used for monitoring, controlling or recording the temperature. Temperature sensors have a wide range of applications in many fields, including but not limited to industrial control, meteorological observation, medical equipment, household appliances, automobiles, aerospace and scientific research. Basic types: 1. Thermocouple: Utilizes the principle of the thermoelectric effect, formed by connecting two conductors of different materials. An electromotive force is generated due to the temperature difference at both ends, and the magnitude of the electromotive force is proportional to the temperature difference. 2. Resistance Temperature Detector (RTD): The resistance value changes with temperature. It is mainly made of platinum, copper, and nickel. It has high precision and good stability and is commonly used for precision measurement. 3. Thermistor: The resistance value changes significantly with temperature and is divided into two categories: positive temperature coefficient (PTC) and negative temperature coefficient (NTC), suitable for temperature switches and temperature compensation. 4. Infrared temperature sensor: Non-contact measurement. It determines the temperature by detecting the infrared energy radiated by the object and is suitable for high-temperature, dangerous or hard-to-reach environments. 5. IC temperature sensor: A miniaturized electronic component integrating a temperature sensing element and a signal conditioning circuit, providing analog or digital output, with flexible use and low cost. Application scenarios: Industrial automation: Process control, equipment monitoring, safety protection. Environmental monitoring: Weather stations, greenhouses, cold chains, water quality analysis. Home appliances and smart homes: Air conditioners, refrigerators, water heaters, intelligent temperature control systems. Medical equipment: Thermometers, pulse oximeters, incubators. Automobiles: Engine temperature monitoring, cockpit environment control. Scientific experiments: Temperature control and measurement in physics and chemistry experiments. Considerations for selection: When selecting a suitable temperature sensor, factors to be considered include measurement range, accuracy, response time, stability, cost, installation method, and whether contact or non-contact measurement is required, etc. Each sensor has its advantages and limitations, so it is necessary to comprehensively evaluate and select according to specific requirements in actual applications.

[0003] However, when the existing temperature sensors are used to detect the temperature of a specific part, the entire sensor needs to be placed at a specific position. This installation method is feasible when the temperature-receiving volume is relatively large, but it will fail for gap parts or narrow structures. Moreover, when measuring the temperature at different depths of the same device, the installation position needs to be constantly changed, making the temperature measurement process extremely complicated.
