专利汇可以提供Temperature controller for liquid vessel专利检索,专利查询,专利分析的服务。并且PURPOSE:To maintain a liquid quickly and accurately at a desired set temperature by arranging a temperature sensor outside the body of a vessel while a heat delay material having a heat delay property roughly equal to that of the body interposed between the temperature sensor and the heater. CONSTITUTION:A flow cell 12 is surrounded with a heater 20 and a Peltier element cooling source 15 is brought into contact with a thermostat frame 13 to alway maintain the thermostat frame 13 at a desired set temperature for example 20 deg.C, lower than 37 deg.C. In other words, the cooling source 15 acts as a sort of heat bias to deviate the temperature of the liquid in the flow cell to the low temperature side. The temperature detected with the temperature sensor 20 is compared with the set temperature as biased to the low temperature side and according to the deviation obtained, the energization of the heater 18 is controlled thereby enabling the maintaining of the liquid in the flow cell at a desired set temperature quickly and accurately.,下面是Temperature controller for liquid vessel专利的具体信息内容。
