Transmitter Operation Transmitter Operation The wireless 4-20mA analog signal transmitter reads analog input data from temperature, pressure, strain, flow, level or RH sensors and then sends the measured data over the air to a remote location. The measured 4-20mA current signals are converted to digital packets and then transmitted via a license free radio transmission to a waiting control receiver.
Receiever Operation Transmitter Operation The wireless 4-20mA analog receiver decodes any incoming radio packets and converts them back into the same 4-20mA current signal that is being measured by the transmitter in real time.
