Pressure Sensors: Applications, Types, And Benefits Zenka Europe UAB

What Are Pressure Sensors?

Pressure sensors, also known as pressure transducers or pressure transmitters, are devices that convert pressure measurements into an electrical signal. This conversion allows for precise monitoring and control in various applications, ensuring safety, efficiency, and performance.

Types of Pressure Sensors

Absolute Pressure Sensors

Absolute pressure sensors measure pressure relative to a perfect vacuum. They are used in applications where precise pressure measurement is crucial, such as in altimeters and barometers.

Gauge Pressure Sensors

Gauge pressure sensors measure pressure relative to atmospheric pressure. These are commonly used in tire pressure gauges and blood pressure monitors.

Differential Pressure Sensors

Differential pressure sensors measure the difference between two pressures. They are vital in applications like flow measurement in pipes and ducts.

Sealed Pressure Sensors

Sealed pressure sensors are similar to gauge sensors but are calibrated to a fixed pressure, not the current atmospheric pressure. They are used in applications where the pressure reference is constant and not affected by environmental changes.
