Pressure Sensor

Electronics make up pressure sensors that take in physical energy (force). When you apply the energy through liquids or gas to the pressure sensor — it then brings the physical energy to an electrical signal, either analog or digital. The pressure sensor also measures the relative pressure to a reference (e.g., Atmospheric pressure, Vacuum, or Sealed Reference) and provides you with physically accurate and current (Real-Time) data able to use in equipment to monitor and control process automation.

Examples of pressure sensing devices include: capacitive, piezoresistive, piezoelectric, and strain gauge technologies. Any of these sensing devices (element) will deform slightly with applied pressure, resulting in a change in electrical property (output signal).

There are three measurement designs based on type and reference type; absolute pressure; gauge pressure and differential pressure. Hence the pressure sensor can set to a number of different measurement types (e.g., liquids, gases and changes in the measurement type of pressure; e.g., Vacuum to Gauge).

Most modern sensors provide small, rugged, low power products, and many of these products can transmit their measured signal real-time and support integration into IoT platform technology.

Applications for pressure sensing are widespread and include industrial automation, HVAC systems, automotive applications, medical devices, hydraulic, Pneumatic and environmental monitoring. Accurate measurement of pressure is critical for operation, safety, efficiency and performance.
