Schematic representation of the membrane orientation in relative pressure measurement with a sensor where the pressure P1 is greater than Pamb.
With the help of relative pressure sensors one compares a pressure in relation to the ambient pressure and receives a signal, which is proportional to the pressure difference.
The sensors offered here are suitable for applications in which there is a fixed ratio between the lower and the higher pressure. The measuring pressure P1 must be greater than the ambient pressure Pamb.
The AMSYS range of relative pressure sensors ranges from simple, uncompensated silicon cells over OEM sensors to high-precision amplified transmitters with standard output values.
