1991年4月11日,我院研制的“WK—411高精度程序温控仪”通过化工部组织的鉴定。过去在冶金、热处理、陶瓷等生产、科研与教学中,要求电阻炉炉温依一定的温度—时间曲线变化,而实际控温通常是由于动控制的各类常规温控仪完成的,则难免使实际温度曲线大大偏离设定值,加之常规仪表的控温精度不高(在±10℃左右),极大地影响产
April 11, 1991, our hospital developed “WK-411 high-precision temperature program ” by the Ministry of Chemical Industry Organization identification. In the past in the metallurgy, heat treatment, ceramics and other production, research and teaching, resistance furnace temperature required by a certain temperature - time curve changes, and the actual temperature control is usually due to various types of conventional control of the temperature controller to complete, it is inevitable So that the actual temperature curve greatly deviates from the set value, combined with conventional instrument temperature control accuracy is not high (at ± 10 ℃ or so), greatly affect the production
