IPC: G01K7/22
Filed: 1981-12-04
Abstract: PURPOSE:To improve the contol accuracy by providing thermistors separately for the low and high temperature areas into which the temperature range to be detected is divided. CONSTITUTION:A thermistor 3 for measuring the low temperature area and a thermistor 4 for measuring the high temperature area are connected in series and a lead wire is connected to the connection point (a) thereof and both ends b, c as terminals. After a necessary treatment for a protective film or the like, the assembly is packaged with a cylinder 2. As the measuring range of the thermistors is divided into the low and high temperature areas, it is assumed that the constant of the thermistors won't be affected by the temperature when RL at the center TL in the low temperature area is selected at the same accuracy as that in the past. Even in that case, the maximum of errors in the low temperature area can be reduced to less than half as compared with the conventional method except for error element.

CONSTITUTION:The pH a culture medium 25 in the cultivation is controlled to be always at the set value by a pH adjusting apparatus 13, and the rate of change in pH is proportional to the amount of a pH adjustor required for controlling the pH of the culture medium 25 at the set value by adding the pH adjustor from the pH adjusting apparatus 13 to be culture medium 25. Thus, the  amount of the pH adjustor added by one opening of a solenoid valve in the pH adjusting apparatus 13 is kept constant, and the amount of the added pH adjustor is determined by multiplying the frequency of addition obtained by integrating the frequencies of the addition of the pH adjustor for a given period by the  constant amount of the pH adjustor added to the culture medium 25 on one  opening of the solenoid valve in the pH adjusting apparatus 13. The measured  amount of the added pH adjustor is calculated by a minicomputer 24 from the operational expression on the basis of the amount of the added pH adjustor to  output controlling output signals from the minicomputer 24 to a flow rate variable pump 14 to feed the substrate to the culture medium 25 at a proper rate.
