Pressure Range That Sensors Can Measure
Typical pressure ranges of several commonly used sensor types
The pressure range that sensors can measure varies depending on the sensor design, type and application area. Different sensor types and models can operate in different pressure ranges. The pressure range is determined by taking into account the sensitivity of the sensor and the pressure characteristics of the medium to be used. Here are typical pressure ranges for several commonly used sensor types:
Open-Ended Pressure Sensors:
These sensors generally measure low pressures and can typically operate in the range of a few inches of water (inH2O) to a few psi (pounds per square inch).
Differential Pressure Sensors:
Differential pressure sensors measure the difference between two different pressure points. These sensors usually measure in millibars or pascals and can operate in the range of a few mbar to several bar.
Gauge Pressure Sensors:
Gauge pressure sensors generally make measurements using atmospheric pressure as a reference. Typically it can operate from a few psi to several thousand psi.
Absolut Pressure Sensors:
Absolute pressure sensors measure using absolute zero pressure as a reference. These sensors usually measure in kPa or bar and can operate from a few kPa to a few bars.
Magnetic Pressure Sensors:
Magnetic pressure sensors are commonly used in industrial applications and can measure pressures ranging from a few psi to several thousand psi.
To determine whether any sensor is suitable for a particular pressure range, it is important to review the technical documentation provided by the manufacturer. There can be large differences between different models and types, depending on the sensors' design purposes, durability levels, and application requirements.
