Many passive field strength meters have appeared in the past, typically using a 50mA analog meter movement if reasonable sensitivity was to be obtained. This circuit is similar but has the advantage ...

The circuit was designed to measure the electric field strength in radio frequency band where it can be applied during the modulation of AM and FM signals in the VHF range. Field Strength – the ...

The problem for Dart Oil and Gas was that production data from its methane gas wells was not available to engineers in the field. Switching from a centralized system using OPC technology and DDE to a ...
