摘要： An improved new type pyrometer and a method for fusing an alumina pipe having a high purity are disclosed. The temperature-measuring portion of the pyrometer includes a protective pipe made of alumina having a purity of at least 99.9% and a temperature-measuring resistance element of a platinum or platinum-rhodium resistance wire and a holding portion made of alumina having a purity of at least 99.9%. Owing to the use of high purity alumina, the platinum or platinum-rhodium resistance wire is not contaminated and has stable temperature characteristics at high temperatures. According to the method of this invention, an end of an alumina pipe having a purity of at least 99.9% can be fused without the aid of any binder by fusing the end while evacuating air from the alumina pipe through its opposite end.

摘要： In a subject fluid, there is placed an apparatus for measuring a change in state of the fluid, said apparatus having a tubular body which, in turn, contains therein at least one heating sensor employing so-called hot wire method. A quantity of the fluid is introduced into the tubular body and a temperature of the heating sensor is measured by the heating sensor itself as the quantity of the fluid having been introduced into the tubular body is maintained in a state of laminar flow or a static state. The laminar flow is generated by fluid impeller means such as impeller vane, screw-type vane or propeller vane assembly or uniaxial eccentric pump. The static state is maintained y providing gateway means for passage of the fluid into or out from the tubular body and closing such gateway means. A temperature of the fluid having been introduced into the tubular body and maintained in said laminar or static state is measured and discharged out from the tubular body upon completion of said temperature measurements. A change in state of the fluid is determined based on the temperatures of the fluid and the heating sensor.

摘要： A heating sensor capable of generating heat and measuring its own temperature is placed in a fluid and a thermometric sensor is placed in the fluid and inside a temperature boundary layer formed around the heating sensor upon heat generation therefrom. A temperature of the heating sensor and a temperature of the fluid are measured. A relationship between thermal conductivity of the fluid and a differential value between the temperature of the heating sensor and the temperature of the fluid is used to determine the thermal conductivity of the fluid. Then, the heating value of the heating sensor is adjustably increased so that the thermometric sensor is positioned outside the temperature boundary layer. A temperature of the heating sensor and the temperature of the fluid are measured. The relationship between kinematic viscosity of the fluid and a differential value between the temperature of the heating sensor and the temperature of the fluid is used to determine the kinematic viscosity of the fluid. Alternatively, a single heating sensor and a pair of the thermometric sensors are used, where one of the thermometric sensors is placed outside the temperature boundary layer, and the other thermometric sensor is placed inside the temperature boundary layer, or a pair of the heating sensors is used with a single thermometric sensor placed outside the temperature boundary layer formed around one of the heating sensors and inside the temperature boundary layer formed around the other heating sensor.

摘要： A method for measuring a heat transfer coefficient between a heat transfer element and a fluid comprising a measurement of a calorific value by placing the heat transfer element into the fluid and charing the heat transfer element with electricity. A calorific value of a particular surface of the heat transfer element is the true calorific value of the entire heat transfer element, since the particular surface of the heat transfer element is thermally insulated from a residual surface of the heat transfer element so as to prevent a heat transfer of the residual surface of the heat transfer element.

摘要： A sensor for measuring the temperature of a liquid or semi-solid material by electrical heating. A core rod has disposed thereon a first electrically insulating member and a thin metal wire is wound about the first insulating member on the core rod. A second electrically insulating member covers the thin metal wire. When an electrical current is passed through the thin metal wire heat is generated in the thin metal wire. The resistance in the thin metal wire is proportional to the temperature thereof, which temperature is proportional to the current passed through the thin metal wire and the temperature of the liquid or semi-solid in which the sensor with the thin metal wire is disposed. Thus the temperature of the liquid or semi-solid can be determined by measuring the voltage or resistance in the thin metal wire by known measuring devices.
