Device for converting a force or a pressure into an electrical signal and method for producing such a device

摘要

A device (1) converts a force or a pressure into an electrical signal and has a first deformation element (10), in particular a first membrane (12), to apply the force or the pressure to the device (1) and a second deformation element (20), in particular a second membrane (22), to convert the deflection of the force or the pressure into an electrical signal. The first deformation element (10) has a first force transmitter (14), and the second deformation element (20) has a second force transmitter (24) for transmitting the force from the first deformation element (10) to the second deformation element (20). The first force transmitter (14) is rigidly connected at its end distant from the first deformation element (10) to the end of the second force transmitter (24) distant from the second deformation element (20). Both compressive forces and tensile force can be transmitted from the first deformation element (10) to the second deformation element (20) by the first and second force transmitters (14, 24). A method produces that device.

1. A method for producing a device for converting a force or a pressure into an electrical signal, comprising the steps of:
forming a first deformation element receiving a force or pressure and having a first force transmitter in a center of the first deformation element; forming a second deformation element that is deflectable, that converts deflection thereof into an electrical signal and that has a second force transmitter in a center of the second deformation element; and welding the first force transmitter at an end thereof distant from the first deformation element to an end of the second force transmitter distant from the second deformation element by resistance welding such that the first and second force transmitters transmit both compressive and tensile forces from the first deformation element to the second deformation element.
