温度探头, 温度传感器类型 & 应用
A temperature probe is a device used to measure temperature, usually consisting of a sensitive element and a measuring circuit. The sensitive element can be a thermocouple (100分, 1000 分), a thermal resistor (ntc, ptc), a semiconductor (DS18B20 digital), ETC。, which can convert temperature changes into electrical signals. Then it is amplified, filtered, converted, and processed by the measuring circuit, and finally an electrical signal proportional to the temperature is output.
什么是数字温度传感器? DS18B20传感器探头的设计
DS18B20 is a commonly used digital temperature sensor probe chip, which outputs a digital signal. It has the characteristics of small sensor probe, low hardware design requirements, strong anti-interference ability and high precision. The DS18B20 digital temperature sensor is easy to wire, and can be used in many occasions after the probe is packaged. Such as pipeline type, 螺纹型, 磁铁吸附式, stainless steel package type, 各种型号, 包括 LTM8877, LTM8874, ETC.
