| 20090180514 | TRANSFORMER AND A METHOD OF MONITORING AN OPERATION PROPERTY OF THE TRANSFORMER - The present disclosure provides a transformer comprising, a transformer core and a tank portion arranged to contain a cooling fluid for absorbing thermal energy from the transformer core. The transformer also comprises a radiator portion which is in fluidal communication with the tank portion and for radiation of at least a portion of the thermal energy absorbed by the cooling fluid. A first temperature sensor is arranged to provide an output that is dependent on a local temperature at the radiator portion. A second temperature sensor is arranged to provide an output that is dependent on a local temperature at another portion of the transformer. The transformer is arranged so that the outputs of the first and second temperature sensors relative to each other are indicative of a level of the cooling fluid or are indicative of a thermal property different from that expected given a power being transformed by the transformer. | 07-16-2009 |
| 20110038393 | ENGINE COOLANT AMOUNT DETERMINING APPARATUS - An engine coolant amount determining apparatus includes an electric water pump that can be operated intermittently while an engine is running, and a coolant temperature detecting means for detecting the temperature of coolant at a location higher than the water pump. The engine coolant amount determining apparatus also includes determining means for determining that the amount of coolant is equal to or less than a predetermined amount when the degree of change in the coolant temperature detected by the coolant temperature detecting means when the water pump is operated intermittently is large. | 02-17-2011 |
| 20140269820 | THERMOWELL INSERT - A temperature sensing system comprises a thermowell, a sensor, and a solid insert. The thermowell extends into a sensing region of a fluid flow. The sensor has a probe housed in the thermowell to sense a temperature in the sensing region. The solid insert is configured to removably support the probe within the thermowell and to provide a thermal contact between the thermowell and the probe. | 09-18-2014 |
| 20140269821 | MULTICHANNEL THERMOCOUPLE COMPENSATION FOR THREE DIMENSIONAL TEMPERATURE GRADIENT - A method of using a thermocouple is provided. The method includes, but is not limited to, disposing at least one temperature sensor at each of two or more respective portions of an electrical connector adapted to receive thermocouple signals, measuring temperatures at the two or more portions, and calculating the temperatures at each terminal of the electrical connector based on measured temperature values of the two or more respective portions having the disposed temperature sensors. The method also includes, but is not limited to, calculating a cold junction temperature of a terminal for at least one thermocouple channel carrying the thermocouple signals based on measured or calculated temperature values of the terminals, or a combination thereof. | 09-18-2014 |
| 20140294041 | METHOD AND SYSTEM FOR DETERMINING FLOW DISTRIBUTION THROUGH A COMPONENT - Systems and methods for determining the flow distribution of a fluid through a component with a sensing cable including an optical fiber sensor array aligned with a heating element disposed in the component. An excitation source is configured to propagate at least one heat pulse through the heating element along at least a portion of the sensing cable to affect an exchange of thermal energy between the heating element and the fluid exposed to the sensing cable. An optical signal is adapted to receive a signal from each of a plurality of sensor locations and measure a temperature profile corresponding to the heat pulse at the sensor locations. A control unit is configured to determine a flow of the fluid by determining one or more properties of the fluid exposed to the sensing cable at each of the plurality of sensor locations based on the temperature profile corresponding thereto. The present invention can be effective in accurate and high spatial resolution of flow distributions through vessel components, such as a particulate bed (such as a reactor catalyst bed), a wash bed including packing material, an absorbent bed, a structured bed, a filter, or the like. | 10-02-2014 |
