Digital Panel Meter
DPM - Bee Instruments (BEE)
Digital panel meters are digital displays intended to be mounted in a panel, such as a control panel. They typically read some type of input, be it a voltage, current, or resistance, and display its value digitally. Often this input is a measurement from a sensor which is converted and displayed as a temperature, pressure, or other system variable. These meters may also act as simple controllers which trip a switch or perform a simple function when the reading reaches a preset measurement.
