점도측정용 항온조의 온도 제어 수단Temperature control means of thermostat for viscosity measurement

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음Since this is an open matter, no full text was included.

제1도는 본 발명의 온도제어 수단을 장비한 점도 측정용 항온조의 전체 외관도,1 is an overall appearance of the thermostat for measuring the viscosity equipped with the temperature control means of the present invention,

제2도는 본 발명의 온도 제어 수단의 계장의 신호 흐름도(instrumental flow sheet),2 is an instrumental flow sheet of the instrument of the temperature control means of the present invention,

제3도는 본 발명에 의한 유체시료의 온도제어의 실시예 그래프.3 is an exemplary graph of temperature control of a fluid sample according to the present invention.

Claims (1)

유체시료를 항온조의 매체욕에 담그고, 여러가지 온도로 그 점도를 측정할 때의 유체시료의 온도를 자동제어 하기 위한 것으로서, 상기 유체시료의 온도를 검출하여, 그 검출온도에 해당하는 제1 출력신호를 발하는 제1 온도계; 상기 제1 온도계로 부터의 상기 제1 출력신호와 상기 유체시료 온도의 설정치에 대한 입력명령을 받아들여, 상기 유체시료의 상기 설정치와의 차이값의 함수로서 조립한 연산식에 따라 상기 매체욕의 온도의 설정치를 결정하고, 이 결정된 매체욕온도 설정치에 해당하는 제1 조절신호를 발하는 제1 조절기; 상기 매체욕의 온도를 검출하여, 그 검출 온도에 해당하는 제2 출력 신호를 발하는 제2 온도계; 상기 매체욕을 가열. 냉각하기 위한 가열. 냉각 수단 및 상기 제2 온도계로 부터의 상기 제2 출력신호와 상기 제1 조절기로 부터의 상기 제1 조절신호를 받아 들여, 상기 제1 조절신호와 상기 제2 출력신호와의 레벨차에 해당하는 제어동작신호를 형성하고, 계속해서 이 제어동작신호에 의거하여 형성한 PID 조절신호를 상기 가열. 냉각 수단에 입력하는 제2 조절기로 이루어져 있으며, 이것에 의해 상기 가열. 냉각 수단이 상기 PID 조절신호에 응답하여 상기 매체욕을 가열. 냉각하는 것을 특징으로 하는 점도측정용 항온조의 온도 제어 수단.It is for automatically controlling the temperature of the fluid sample when the fluid sample is immersed in the medium bath of the thermostat and the viscosity is measured at various temperatures. The first output signal corresponding to the detected temperature is detected by detecting the temperature of the fluid sample. A first thermometer for emitting; Accepts an input command for the first output signal from the first thermometer and a set value of the fluid sample temperature, and assembles it as a function of the difference between the set value of the fluid sample and the A first regulator which determines a set point of the temperature and issues a first control signal corresponding to the determined medium bath temperature set point; A second thermometer which detects a temperature of the medium bath and emits a second output signal corresponding to the detected temperature; Heat the medium bath. Heating to cool. The second output signal from the cooling means and the second thermometer and the first control signal from the first regulator are received and correspond to a level difference between the first control signal and the second output signal. The control operation signal is formed, and then the PID control signal formed on the basis of the control operation signal is heated. And a second regulator input to the cooling means, whereby the heating. Cooling means heats the medium bath in response to the PID control signal. The temperature control means of the thermostat for viscosity measurement characterized by cooling. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
