摘要： PURPOSE:To obtain the highly reliable result of the measurement of the radiation temperature by always measuring the transmittance of a radiation path, and performing compensation. CONSTITUTION:An object 10 whose temperature is to be measured is carried into a furnace by a trasporting roll. Radiating sources 12 and 14 are provided in the furnace and a radiometer 16 is provided at the outside of the furnace. The radiations 22 and 26 are received by the radiometer 16, and the radiations 28 and 30 which directly come from black-body radiation sources 12 and 14 are also received by the radiometer 16. An operation display device 32 performs the operation based on the received-light output from the radiometer 16, outputs the result of the accurate temperature measurement whose transmission factor is compensated, and displays the temperature of said object. The radiations 22, 26, 28, and 30 are inputted into the radiometer by switching. Said switching is performed so that each radiation is irradiated to the light receiving element of the radiometer one by one by a rotating mirror by utilizing the difference in the incident angles of the radiations.

摘要： PURPOSE:To facilitate the maintenance while simplifying the construction of a temperature meauring device by arranging a radiometer outside a furnace so as to receive radiation energy or the like from a black body provided outside the furnace facing the opening of a cooled shielding plate mounted on the furnace wall. CONSTITUTION:A cooled shielding plate as a water-cooled plate is provided on the wall 10 of a furnace on which a strip or the like is running while a black body furnace 14 is provided outside the furnace facing an opening 20 of the plate 18 by way of a seal device 22. A radiation energy from a cold black body furnace formed by the plate 18, the hot black body furnace 14 and a moderate temperature black body furnace formed by the wall 10 near the plate 18 is detected with a radiometer 16 provided outside an opening of the furnace wall 10 facing it via a strip 12 and the temperature of the surface of a strip 12 can be measured accurately by averaging a number of measurements regardless of oscillation of the surface thereof. As the black body furnaces and the radiometer are all set up outside the furnace and only one set of the black body furnaces are required structurally, this can simplify the mechanism in a smaller size while facilitating the maintenance.

摘要： PURPOSE:To make it possible to continuously control in an automatic operation state, by using a temperature signal of the second temperature control unit, in case when something abnormal has occurred in the temperature detection system of the first temperature control unit. CONSTITUTION:In case when the function of the first temperature detector 111 of the first temperature control unit 11 is normal, the amount to be controlled which flows in order from the first temperature control unit 11 to the second temperature control unit 12 is maintained to the prescribed temperature at the point A and the point B. If the first temperature detection system 111 has gone wrong, the abnormality detector 131 of the control change-over device 13 detects it in an instant, and changes the first and second change-over switches SW1, SW2 to the abnormal side, that is, the side shown by a dotted line. As a result, the first and second temperature control units 11, 12 are released from the cascade control, the cascade control is executed by the third temperature controller 131 of the control change-over device 13 which makes an output of the second temperature detector 121 its output, and the first flow rate controller 116, and the temperature of the amount to be controlled at the point A where the first flow rate controller 126 controls the flow rate of fuel is maintained to the prescribed value by the temperature of the point B.

摘要： PURPOSE:To improve controllability of a large-sized fan, to ensure safety in its operation and to conserve energy in operating the same, by employing such an arrangement that the control sensitivity of a load-control regulator can be varied automatically depending on the operational condition. CONSTITUTION:In case of carrying out load control on the basis of pressure, the output signal of a pressure-signal transmitter 1 is given to both of a low-sensitivity regulator 2 (its control sensitivity is, for instance, 100% in proportionality, 25sec in integration and differentiation OFF) and a high-sensitivity regulator 2' (its control sensitivity is, for instance, 20% in proportionality, 5sec in integration, and differentiation OFF). A control signal afforded via a selector switch 3 is given to an actuator 6 for controlling the revolutional speed for load control, angle of stator blades, etc. while changing the pressure regulating output slowly by an output processing unit 5 so as to prevent confusion of control due to the selecting process. With such an arrangement, it is enabled to eliminate interference between a surging preventing system and a load control system even in the region near the surge- preventing blow-off line and thus to ensure safety in the operation of the system.

摘要： PURPOSE:To stabilize combustion in a low flow rate region where flow rate measurement is incorret and combustion of a burner is unstable by a method wherein valve opening is controlled on the basis of a valve opening -time characteristic previously memorized in the low flow rate region of interest. CONSTITUTION:In a burner which control valves 3, 4 for requlating flow rates are each mounted to a combustion air A supply piping 1 and a combustion fuel G supply piping 2 and the valve opening is controlled by positioners 5, 6, a controller 9 is provided which a valve opening-time characteristic in the low flow rate regions of the control valves 3, 4 is previously memorized. The valve opening of the control valves 3, 4 is controlled by giving the positioners 5, 6 signals SA, SG from the controller 9 based on the extinguishing signals C of the burner. The said valve opening-time characteristic is set by computing the quantity of valve opening variation per unit time by an effective flow rate characteristic previously determined and the optimum air-fuel ratio m0 if the furnace is extinguished or ignited keeping mo even in the low flow rate region.
