Radar level gauge
Thread Content
The output current of the radar level gauge is only around 3.55 milliamps, but sometimes it works fine. Replacing the module doesn’t change anything – what’s the issue? Does anyone know? {:9010:}
Is it in an empty can state? Check whether the empty mark, full mark, and blind zone settings are correct.
Reconnect the power board, processing board, and signal board. If it still won’t start with a current of just a few milliamps, it’s either due to poor contact or significant temperature drift in some components; if reconnecting them doesn’t work, send it back to the factory
Check whether there is output locking; otherwise, cleaning is the only option
