2 The construction of temperature sensorTemperature is a fundamental physical quantity. In the nature all processes are closely related to temperature. According to the law of wave interaction with matter. Successively developed Acoustic temperature sensor, infrared sensor and microwave sensor. The four main types: thermocouples, thermistors, resistance temperature detector (RTD) and IC temperature sensor temperature sensor. IC temperature sensors, including two types of analog output and digital output.5 Teomatic of temperature sensor-------ThermocoupleA thermocouple consists of two conductors of different materials (usually metal alloys) that produce a voltage in the vicinity of the point where the two conductors are in contact. The voltage produced is dependent on, but not necessarily proportional to, the difference of temperature of the junction to other parts of those conductors. Thermocouples are a widely used type of temperature sensor for measurement and control [1] and can also be used to convert a temperature gradient into electricity. Commercial thermocouples are inexpensive,[2] interchangeable, are supplied with standard connectors, and can measure a wide range of temperatures. In contrast to most other methods of temperature measurement, thermocouples are self powered and require no external form of excitation. The main limitation with thermocouples is accuracy; system errors of less than one degree Celsius (C) can be difficult to achieve3 the Classification of temperature sensorContact temperature sensor：The contact temperature sensor detecting section have good contact with the measured object. Also known as a thermometer.Non-contact temperature sensor：Its sensitive element and the object to be measured is not in contact with each other. Also known as non-contact Thermometer. This instrument is used to measure moving objects, small targets, a small thermal capacity or rapid temperature changes in the surface temperature of the (transient) objects. Can also be used to measure the temperature of the temperature field distribution.4 The type of temperature sensorInfrared temperature sensor：Infrared (IR) radiation is part of the electromagnetic spectrum,which includes radio waves, microwaves, visible light, and ultraviolet light, as well as gamma rays and X-rays. Analog temperature sensor：Traditional analog temperature sensors such as thermocouples, the thermistor and RTDS temperature monitoring. Linearity is not good in some temperature range. The need for cold junction compensation or lead compensation, thermal inertia, slow response times. Integrated analog temperature sensor compared. With the advantages of high sensitivity, good linearity, fast response. And it will also drive the circuit, the signal processing circuit, as well as the necessary logic control circuits are integrated on a monolithic IC, a small actual size, ease of useLogic output temperature sensor：In many applications. We do not need to strictly measure the temperature value. Only care about whether the temperature is beyond the scope of a set. Once the temperature exceeds the specified range, the alarm signal. Start or turn off fans, air conditioners, heaters, or other control devices. The optional logic output temperature sensor.6 select the right temperature sensorIf you want to make reliable temperature measurements. First you need to select the correct temperature meter. Also is a temperature sensor. The thermocouples, thermistors, platinum resistance (RTD), and the temperature IC is the most commonly used temperature sensor in the test.Thermocouples are the simplest and most common temperature sensor. But the thermocouple is not suitable for high-precision measurement applications.The Thermistor have its measurement techniques. The size of thermistor is small. Can stabilize soon, will not cause the heat load. But it is fragile. If Large current across will cause self-heating. The thermistor is a resistive device. Any current source will power on fever. Power is equal to the square of the current resistance plot. So to use a small current source. If the thermistor is exposed in the heat. Will lead to permanent damage.7 Development trendsAfter entering the 21st century. Smart temperature sensor is moving in high-precision, multi-function bus standardization, high reliability and security, the development of a virtual sensor and network sensor developed single-chip temperature measurement system and other high-tech direction rapidly. Smart temperature sensor bus technology to achieve standardization and normalization. Single line (1-Wire) bus, I2C bus, SMBus bus and spI bus in the bus. Temperature sensor as a slave by the dedicated bus interface with the host communications.。
