Abstract (en)
[origin: DE19527687A1] A testable and highly available sensor has a measurement membrane that bears the resistances of two different full bridges. On the right half (4) radial compressions (R1, 4) and extensions (R2, 3) are used, on the left half (3) radial compressions (R1, 4) but tangential extensions (R2, 3) are used. Ageing phenomena influence the sensitivity of both full bridges to a different extent, so that the sensor may be tested during its operation without any special reference measurements. In addition, one full bridge may be used in an emergency when the other full bridge breaks down.
