A pressure sensor is a measuring device used to monitor the pressure of gases or liquids within a system and convert that measurement into an electrical signal that can be read by a controller, display, or monitoring system. It helps ensure that pressure levels stay within safe and optimal limits, preventing equipment damage, product defects, and unsafe operating conditions. Pressure sensors provide real-time visibility into system performance, which is critical for automated and safety-critical processes.

Pressure sensors are widely used in pneumatic and hydraulic systems, HVAC, process industries, automotive systems, water management, and medical equipment. They come in various types such as absolute, gauge, and differential pressure sensors, each suited for different measurement needs. By using pressure sensors, operators can improve process accuracy, increase energy efficiency, enable predictive maintenance, and quickly detect leaks, blockages, or abnormal conditions before they become serious problems.
