在温度自动控制系统中,为了对被控温对象的准确可靠地控制,必须重视采用正确的现场校验方法监视炉温动态。本文介绍作者设计的能够测量且校正温控系统的测一校温热电偶装置。一、热电偶曾发生过的故障我厂六十年代由日本引进的可控气氛热处理炉淬火炉壁上安装有两支热电偶,其中一支EU-2作测量,并连接电子电位差计,另一支
In the automatic temperature control system, in order to accurately control the temperature controlled object, we must attach importance to the use of the correct field calibration method to monitor the furnace temperature dynamics. This article describes a thermocouple device designed by the author to measure and calibrate a temperature control system. First, the thermocouple had a fault occurred I plant in the 1960s imported from Japan by the controllable atmosphere heat treatment furnace quenching furnace installed on the wall with two thermocouples, one of the EU-2 for the measurement, and connect the electronic potentiometer, Another one
