Abstract:
An application temperature pickup device is provided for autonomously measuring the temperature of a thermal-energy-having container, with a housing to be secured to the container, a temperature sensor which measures the temperature of a measuring surface of the outer wall of the container and rests thereon, and associated electronics which are arranged in the housing, as well as a thermoelectric generator which conducts away through the flow of heat the thermal energy of a tapping surface of the outer wall of the container and which has the purpose of supplying energy to the temperature sensor and the electronics, wherein the measuring surface is arranged separated from the tapping surface by a distance in order to reduce the exchange of heat with the tapping surface.
Abstract:
A thermometer has at least one temperature sensor, having a physical variable which changes in a characteristic manner depending on temperature, at least one electrical output for emitting a signal which is a measure for the value of the variable, a transmitter for a sound wave or an electromagnetic wave, which transmitter can be coupled to the temperature sensor and controlled thereby depending on the variable's value, or can radiate the wave at least in part towards the temperature sensor, the wave-temperature sensor interaction depending on the variable's value, and either a wave receiver, which reconverts the wave into an electrical signal, or another unit for converting the wave-temperature sensor interaction into an electrical signal, connected to the electrical output.
