Introduction to Pressure Sensors and Transducers

Pressure sensors (or Transducers) are one of the most commonly used tools in environmental and industrial engineering, as well as in small and large businesses. Pressure sensors detect and measure pressure using the electrical or mechanical properties of different materials which are located inside the device. They are therefore able to accurately measure the pressure of a fluid or gas, and display the readings on a monitor or specialized data collecting devices. The pressure can be set accurately and recorded quickly and accurately with the help of these sensors.

Types of Pressure Sensors

Pressure sensors come in a variety of types, depending on the application they are used for. The different types include Absolute, Differential, Gauge, Vacuum, and Digital Pressure Sensors. Each of these serves a different purpose and provides different capabilities. Absolute pressure sensors measure pressure relative to a full vacuum. They are typically used to measure the pressure of a sealed system where the external pressure remains stable. Differential pressure sensors measure pressure differences between two points. They are typically used where the pressure of one point can change significantly without affecting the other. Gauge pressure sensors measure pressure relative to atmosphere, and are used when the environmental pressure is subject to change. Vacuum pressure sensors measure negative pressure or vacuum, and can be used in a variety of industrial and environmental applications. Finally, digital pressure sensors are often used for applications requiring precise readings, as they provide accurate, reliable readings with minimal human intervention.
