Basic System Operation

WIRELESS 4-20MA INPUT TRANSMITTER

The wireless 4-20 mA 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 receiver.

 WIRELESS ANALOG OUTPUT RECEIVER

The wireless 4-20mA analog receiver decodes any incoming radio packets and converts them into an analog voltage output scaled to match the same 4-20 mA current signal that is being measured by the transmitter in real time. 

 ANALOG SIGNAL CONVERTER MODULE (Included with Transmitter/Receiver)

The analog signal converter accepts the 0-5V DC signal coming from the wireless receiver and converts the voltage back into a 4-20 mA output signal. The converter module is factory calibrated.

With your receiver before it is shipped to you. The converter module features both 4mA (Zero) and 20mA (Span) adjustment potentiometers so small adjustments can be made in the field.
