Abstract:
A sensor, comprising a measuring diaphragm; and a resistor measurement bridge means arranged on said measuring diaphragm so that a deflection of said measuring diaphragm causes mis tuning of said measuring bridge means and a resulting change in a bridge diagonal voltage is evaluatable, said resistor measurement bridge means including a first resistor measurement bridge and a second resistor measurement bridge each arranged on each half of said measuring diaphragm, said first resistor measurement bridge having all four bridge branches which are acted upon by radially acting mechanical tensions on said measuring diaphragm and said bridge branches stressed by radial elongation being located in a center of said measuring diaphragm, said second resistor measurement bridge unlike said first resistor measurement bridge having bridge branches that are acted upon by a tangential elongation and located in a peripheral region of said measuring diaphragm and oriented such that tangential mechanical tensions act upon them.
