What Are Types of Pressure Sensors?

sensor pressure types

When it comes to measuring pressure with sensors, there are a variety of different types you can use depending on the application. These types include absolute pressure, gauge pressure, differential pressure, and vacuum pressure.

  • Absolute Pressure Sensor – measures pressure relative to a vacuum and is vital in fields such as aviation and space exploration.
  • Gauge Pressure Sensor – or relative pressure sensor, measures pressure relative to atmospheric pressure and is often used in industrial and commercial applications.
  • Differential Pressure Sensor – measures the difference between two pressure points and is utilized in fluid flow measurements.
  • Vacuum Pressure Sensor – measures vacuum or sub-atmospheric pressures and is often used in applications such as vacuum pumps.

How Does a Pressure Sensor Work?

  • Piezoelectric Sensors are a type of sensor that converts mechanical stress or pressure into electrical charges.

working principle: This effect is the generation of an electric charge or voltage when a material experiences mechanical stress, such as pressure or vibration. Crystals and ceramics are commonly known to exhibit this phenomenon. Upon the application of mechanical force to the crystal or ceramic, the material undergoes deformation, subsequently leading to the generation of an electrical signal. The output signal produced by a piezoelectric sensor directly correlates with the magnitude of the mechanical stress or pressure exerted upon it. This relationship enables the precise quantification and measurement of mechanical forces through the utilization of piezoelectric sensors.

  • Piezoresistive sensors are pressure elements that sense changes in pressure, force, and acceleration.

working principle: Piezoresistive sensors are pressure elements that sense changes in pressure, force, and acceleration.
working principle: Piezoresistive sensor work is based on the piezoresistive effect, a phenomenon in which the electrical resistance of a material changes in response to an applied mechanical strain. This allows the sensor to convert mechanical signals into electrical signals that can be interpreted and processed by electronic systems. These sensors are commonly used in automotive airbag systems, electronic scales, and biomedical instrumentation. Because of their great sensitivity, low power consumption, and compatibility with common electronic fabrication processes, they are favored over other types of sensors.

  • Capacitive sensors are highly sophisticated electronic devices designed to measure the changes in capacitance that occur due to the proximity or touch of an object.

working principle: Capacitive sensors operate based on the fundamental principle of capacitance, which pertains to the capacity of two conductive surfaces to accumulate electrical charge when they are isolated by a non-conductive material. A capacitive sensor consists of two conductive plates separated by a dielectric material, often air or vacuum. An electric field is created within the dielectric material by providing voltage to one of the plates, which causes a change in the sensor’s capacitance. This variation in capacitance can be utilized for diverse purposes, such as detecting the presence or absence of an object, measuring its distance or displacement, or even discerning its physical attributes, including weight or pressure. Capacitive sensors thus leverage the intricate interplay of capacitance to enable precise and versatile sensing capabilities across numerous applications.

  • Optical sensors possess the capability to transform incident light into electrical signals. This distinctive functionality facilitates the identification and precise quantification of alterations transpiring within the surrounding environment.

working principle: The working principle of the optical sensor involves the conversion of a physical parameter, such as pressure or temperature, into a variation in the optical properties of a material. This change is detected and processed to provide a signal that can be analyzed and interpreted.
