Abstract
The invention provides a pressure detector which has a small temperature-related measurement error, can be used in particular for small measurement ranges and has a sensor element (1), a sensor diaphragm (11) secured at its border, the non-secured parts of which sensor diaphragm can be deflected on account of the pressure which is to be measured, a housing (2), fastening means (3) for fixing the border of the sensor diaphragm (11) in the housing (2), a diaphragm (4) which closes off the housing (2) and is to be supplied with a pressure which is to be measured, and a solid body (5) with a modulus of elasticity which is suitable for minimizing the temperature-related measurement error, which solid body is arranged between the diaphragm (4) and the deflectable part of the sensor diaphragm (11) and which solid body transmits the pressure from the diaphragm (4) to the sensor diaphragm (11).
