The HTS Series is a surface-mountable pressure sensor that offers you a choice between an analog or digital output. But the HTS Series is not just your typical surface-mount device. Due to its backside-pressure-measurement design, the sensor’s electronics are isolated, making the HTS Series compatible with wet, corrosive media. Learn more.
What is media? Show Answer
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? Show Answer
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? Show Answer
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.
