本文介绍热电偶和热电阻温度传感器在安装及更换时所要注意的事项和要求。 1.温度传感器的分度必须与测温仪表相同。与仪表不同分度的温度传感器不可配套使用 [如:铂铑_（10）—铂热电偶WRP必须与S型仪表配套;镍铬—镍硅热电偶WRN必须与K型仪表配套:铂电阻WZP必须与Pt100仪表配套等]。 2.温度传感器在安装使用前,必须进行检定,以淘汰不合格产品及传感器内芯错装“+”“-”极调错等问题,保证测温示值的准确可靠。
This article describes the thermocouple and RTD temperature sensor installation and replacement precautions and requirements. 1. The temperature sensor graduation must be the same with the thermometer. The temperature sensor with different graduation from the instrument can not be used [such as: Platinum and rhodium _ (10) - platinum thermocouple WRP must be matched with S type instrument; NiCr-NiSi thermocouple WRN must be matched with K type instrument: Platinum resistance WZP Must be paired with Pt100 instrument, etc.]. 2. Before the temperature sensor is installed and used, the verification must be done to eliminate the problems such as “+” “-” misjudgment of the unqualified product and the sensor core, so as to ensure the accurate and reliable temperature measurement indication.
