Temperature sensor refers to a sensor that can sense temperature and convert it into a usable output signal. Temperature sensor is the core part of temperature measuring instruments and there are many varieties. According to the measurement method, it can be divided into two categories: contact type and non-contact type. According to the sensor material and electronic component characteristics, it can be divided into two categories: thermal resistor and thermocouple.

PT100/PT1000溫度擷取電路方案

鎳等金屬熱電阻, 銅鉑電阻的阻值隨溫度的變化呈正相關. 鉑具有最穩定的物理和化學性質,用途最廣泛. 常用鉑電阻Pt100的測溫範圍為-200~850℃. 另外, Pt500的溫度測量範圍, 鉑1000, ETC. 都在陸續減少. 鉑1000, 溫度測量範圍-200~420℃. 依據IEC751國際標準, 鉑電阻Pt1000的溫度特性符合以下要求:
