7151—DM型控温仪的控温系统由交流感温电桥、交流放大器、相敏放大器、控温执行继电器四部分组成。其感温元件是热敏电阻。该仪器因其时间常数较小、控制精度较高,更主要的是其价格便宜故其应用较为广泛。我们在搞“制(麦曲)机械化及自控的研究”科研实践中,在控制(麦曲)子生长的“品温”、“室温”中,使用了不少7151——DM型控温仪。通过两年多的实践感到该仪器尚有改进之必要,以适应制酒、酱油等酿造行业生产之需要。 1.该控温仪用于(麦曲)霉生长过程中的控温时与一
7151-DM-type temperature controller temperature control system by the exchange temperature bridge, AC amplifier, phase-sensitive amplifier, temperature control relay is composed of four parts. The temperature sensing element is a thermistor. The instrument because of its smaller time constant, higher control accuracy, more importantly, its cheap so its application is more extensive. We are engaged in “system (Maqu) mechanization and self-control research ” scientific research practice, in the control of the growth of the “product temperature ”, “room temperature ”, using a lot of 7151- -DM-type temperature controller. Through more than two years of practice, the instrument still needs to be improved to meet the needs of brewing, soy sauce and other brewing industries. 1.
