Digital Panel Meter

Digital Panel Meters are usually intended to be mounted in Control Panels. They read some type of input, like voltage, current, frequency, resistance, etc., and display the value digitally. Quite often, this input may be a measurement from a sensor, which is then converted and displayed as temperature, pressure or other system variables.
Digital Panel Meters can also act as controllers that can trip a switch or perform simple functions, triggered when the reading reaches a preset measurement.
