温度传感器是指能感受温度并转换成可用输出信号的传感器。温度传感器是温度测量仪表的核心部分，品种繁多。按测量方式可分为接触式和非接触式两大类，按照传感器材料及电子元件特性分为热电阻和热电偶两类。

Temperature sensor refers to a sensor that can sense the temperature and convert it into an available output signal. Temperature sensor is the core part of temperature measuring instrument, which has a wide variety. According to the measurement method, it can be divided into contact type and non-contact type. According to the characteristics of sensor materials and electronic components, it can be divided into thermal resistance and thermocouple.

 

Graeff温度传感器可用于塑料挤出机、化纤纺丝设备、食品机械、熔盐发电系统、注塑机、汽车、医疗等各种设备的温度测量。 

Graeff temperature sensor can be used as temperature measurement of plastic extruders,chemical fiber spinning equipment, food machinery, molten salt power generation systems, injection molding machines, automobiles, medical equipment and other equipment.

 

Graeff温度传感器研发出两个系列的产品。一种是以热电偶作为温度测量仪表的常用测温元件，直接测量温度，并把温度信号转换成热电动势信号，通过电气仪表（二次仪表）转换成被测介质的温度。另一种温度传感器运用热电阻，其能在0-150°的温度范围内检测，最高检测范围可达600°左右（可检测负温度）。常用铂和铜制作。现在也开始采用镍、锰和铑等材料制作热电阻。 

Graeff temperature sensor has developed two series of products. One is to use thermocouples as common temperature measuring elements of temperature measuring instruments to directly measure the temperature, convert the temperature signal into thermoelectric EMF signal, and convert it into the temperature of the measured medium through electrical instruments (secondary instruments). Another kind of temperature sensor uses thermal resistance, which can detect in the temperature range of 0-150 °, and the maximum detection range can reach about 600 ° (negative temperature can be detected). It is usually made of platinum and copper. Now, materials such as nickel, manganese and rhodium are also used to make thermal resistors.
