Digital Panel Meters

Digital panel meters are devices that convert an input signal into a digitally displayed value. They are mounted in control panels where monitoring and control is taking place. Input signals are often measurements from sensors which are then converted and displayed as pressure, temperature or other system variables. Some digital panel readers can perform simple control functions when readings reach a preset measurement. 

Digital panel meters have more options to consider other than basic display. Some provide data interface functionality that allows the user to interact with information that is displayed. Some allow users to preset input values that trigger alarms or control functions when reached or exceeded. Some meters provide an analog output proportional to the input signal for use in analog devices. 

Analog panel meters still remain appropriate for some applications, however, they have largely been replace by digital panel meters, which are easier to read and far more accurate. Digital panel meters are used extensively in process control and electrical equipment. They are used to monitor voltage fluctuations in large industrial motors and can be used for sub-metering applications to track real-time power conditions and monitor equipment to increase network reliability and power availability.
