A gauge is an instrument that serves as a visual display for the readings obtained from a sensor. It converts the sensor's output into a format easily interpretable and manageable by the user. This conversion allows for the real-time monitoring and assessment of various physical quantities, such as temperature , pressure , speed, or volume, facilitating immediate user interaction and decision-making. Gauges are integral in numerous fields, ranging from automotive dashboards to industrial machinery, providing critical information that helps ensure operational safety, efficiency, and control. By translating complex sensor data into user-friendly displays, gauges play a crucial role in simplifying the monitoring and management of systems and processes.
