Abstract: A temperature sensor comprising a housing having a housing body and a housing chamber, in which housing chamber are arranged terminally two temperature sensor elements, which are especially embodied as thin-film resistance thermometers, one of the temperature sensor elements is heatable, and from each temperature sensor element at least one connection wire leads away, which is connected with a circuit board. The circuit board is arranged in the housing chamber. The circuit board is positioned in the housing chamber by a snap-in connection. A connection wire of a first temperature sensor element is led with strain relief in a first direction through the circuit board and connected with such. The housing chamber contains at least a first elastic body. The circuit board has a first number of cavities, for connection of connection wires and/or cables and a second number of cavities, for reducing thermal expansion of the circuit board. Also presented is a thermal, flow measuring device.
