Used to display an input signal in either an analog or digital form, panel meters come in a variety of models and measurement types to suit your desired implementation needs. Often manufactured with an alarm to alert an engineer of measurements exceeding a predetermined threshold, it is mandatory for meters to remain in working order to prevent part failure or a potentially hazardous accident. As such, specialized equipment that allows panel meter data to be transferred to a computer for future reference and analysis can also be applied. Necessary for determining what measurements are currently being relayed throughout a system, they are built to read, input, and display signals. Without the use of such tools, various power systems, voltage transformers, actuators, and other devices can be negatively impacted. As they share a similar range in variable measurement capabilities, we will discuss the differences between digital and panel meters, their components, and why they are important for electrical applications.
