Vacuum Sensing MEMS Pirani Sensor Basic Knowledge

These are MEMS type pirani vacuum sensors. Pirani Measurement Principle. The measurement principle of a pirani vacuum gauge is rather simple. A metal wire is heated by an electric current. If the wire is in a perfect vacuum, there is no gas and therefore no heat loss. In real conditions (not perfect vacuum) the surrounding gas will remove heat/energy from the wire. The amount of removed heat ...

MEMS Accelerometers | Silicon Sensing

MEMS accelerometers are used wherever there is a need to measure linear motion, either movement, shock or vibration but without a fixed reference. They measure the linear acceleration of whatever they are attached to. Acceleration is measured in m/s 2, but the convention for accelerometers is in ‘g’, or units of gravity, 1g being /s 2.
