Hello dear colleagues,

Pressure sensors and vacuum sensors are both devices that measure pressure, but they are typically used in different contexts and measure different ranges of pressure.

    Pressure Sensor: A pressure sensor measures pressure, typically of gases or liquids. Pressure can be measured in absolute terms, relative to a vacuum (absolute pressure), or relative to atmospheric pressure (gauge pressure). These sensors are typically used in contexts where the pressure is greater than or equal to atmospheric pressure.

    Vacuum Sensor: A vacuum sensor measures the pressure relative to a perfect vacuum. In other words, it measures how much above a perfect vacuum the pressure is. It's used in contexts where the pressure is less than atmospheric pressure. Vacuum pressure is also sometimes called negative pressure because it's below atmospheric pressure.

In essence, the key difference between the two is the range of pressure they measure. A pressure sensor is designed to measure positive pressure (pressure that is greater than atmospheric pressure), while a vacuum sensor is designed to measure negative pressure (pressure that is less than atmospheric pressure). Some sensors are capable of measuring both and might be referred to as pressure/vacuum sensors.
