One Sensing Element Within Another Patents (Class 374/196)
  • Patent number: 7618187
    Abstract: An electromechanical temperature detection device for a cooking appliance comprises a first rod-shaped sensor part and a second tubular-shaped sensor part. The first sensor part and the second sensor part are made from materials having different thermal expansion co-efficients. The first sensor part is positioned inside the second sensor part. An end area of the first sensor part is connected to the second sensor part in the end area of the second sensor part and the opposite end area of the first sensor part is connected to a switching device. The second sensor part consists of a sheet metal stamped part which is embodied along a longitudinal axis such that it surrounds a longitudinal area in a tubular like manner with a first sensor part positioned inside the tubular part.

  • Patent number: 6971533
    Abstract: A pressure cap for a fixed neck of an automobile radiator is provided with an outer cap component and with an inner cap component which has a flow connection between the inside and the outside of the tank and a valve arrangement for releasing and blocking the flow connection. The invention allows the bias of the pressure-relief valve body to be adjustable while the temperature inside the tank can be measured directly and the action of the pressure-relief/vacuum valve body remains constant, it is provided that the bias with which the pressure-relief valve body is pressed against the sealing seat can be adjusted by means of a thermal drive in the form of an expansion-material membrane capsule which has a temperature sensor that passes through the cap axis and extends into the tank's neck, and it is also provided that the vacuum valve body is arranged eccentrically in relation to the cap axis.

  • Patent number: 4607435
    Abstract: A temperature-compensated borehole extensometer comprises a coaxial remotely anchored assembly of a rod and tube formed of materials having disparate linear coefficients of expansion, said assembly being associated with comparator transducers sensitive to relative linear movement of the rod and tube components under the influence of temperatures.
