Power plants use indicators to monitor process parameters such as pressure, flow, temperature, voltage, current, and vibration. Unless a facility is relatively new, it likely has analog panel meters; ...

Power meters like the Kill-A-Watt are great for keeping track of energy usage, and are also very hackable. The Kill-a-Watt in particular puts out analog signals proportional to current and voltage, ...

Chroma's power meters are designed for both single-phase and multiple phase measurements of AC power signals and related parameters common to most electronic products. Chroma's power meters are ...
