The RS Series is an uncompensated, packaged piezoresistive pressure sensor and transducer that is simple to integrate into your product. Ideally a surface-mount device (SMD), the RS Series can also be easily soldered to wires, ribbon cables, and flex strips. The pressure port makes connecting the sensor to the source of pressure easy. This can be done via O-ring or tubing. The RS Series is a flexible product with excellent media compatibility.
What is media?
Media is the environment to which the sensor is exposed. It is typically some form of air, liquid, or gas. Some media can damage a sensor and/or its electronics.
What is backside pressure?
The backside of the MEMS die, or chip, is the side that has had a cavity etched into it to create the die’s thin sensing diaphragm. The pressure reaches the backside of the die through the sensor package’s pressure port. This design enables the RS Series to be compatible with liquids as well as gases and air.
What is the difference between absolute and gage configurations?
With an absolute configuration, i.e. an absolute pressure sensor, the MEMS die has been configured with a sealed cavity on the side opposite the pressure side. With a gage configuration, however, no sealed cavity exists. Therefore, one side of the MEMS die is exposed to the incoming pressure (e.g., from a liquid), and the other side of the MEMS die is exposed to ambient pressure.
