Rõhuandurilt

Rõhuandurilt, commonly translated as pressure sensor, is a device that converts pressure into an electrical signal. This signal can then be measured, transmitted, and processed to provide information about the pressure being exerted on the sensor. Pressure sensors are ubiquitous in modern technology and play a crucial role in a wide variety of applications, from industrial automation to automotive systems and medical devices.

The working principle of a pressure sensor typically involves a sensing element that deforms or changes its physical properties when subjected to pressure. This deformation or change is then translated into a measurable electrical output, such as a change in voltage, current, or resistance. Various sensing technologies exist, including piezoresistive, capacitive, piezoelectric, and strain gauge methods, each offering different advantages in terms of accuracy, sensitivity, and operating range.

The applications of pressure sensors are extensive. In the automotive industry, they are used to monitor tire pressure, engine oil pressure, and fuel pressure. In industrial settings, they are vital for process control, monitoring fluid levels, and detecting leaks in pipelines. Medical devices rely on pressure sensors for blood pressure monitoring, respiratory monitoring, and infusion pumps. They are also found in consumer electronics, weather stations, and aerospace systems. The continuous development of pressure sensor technology aims to improve accuracy, reduce size and cost, and enhance durability in demanding environments.
