Abstract (en)
[origin: GB2462293A] A temperature sensing device 10 includes a probe 5 in contact with the body under test 6. The device 10 prevents heat transfer to or from the body under test 6 by delivering heat energy to or from the probe 5 using a thermal energy supply. The thermal energy supply can take the form of a heating/cooling source 3. The temperature sensing device 10 also includes a heat flux sensor 4. A temperature difference between the probe 5 and the heating/cooling source 3 drives a heat flux through the heat flux sensor 4, which generates a signal that passes through a feedback control circuit 2 which drives/controls the heating/cooling source 3 in response thereto. The temperature of the heating/cooling source 3 is measured via a thermometer element 7 and displayed on a thermometer display 1. Once the heat flux is zero, an indicator 8 is activated to indicate the temperature of the body under test 6 has been reached, the temperature being displayed on the thermometer display 1. A method for determining the temperature of a body under test is also disclosed.
