Page 4: General Sensor Installation
Install the sensor in a way that will avoid these conditions. e. All Global Water water level sensors produce a 4-20 mA output signal. 4-20 mA is an industrial standard signal for process control monitoring. Most PLCs (Programmable Logic Controller), RTUs (Remote Telemetry Unit), and data acquisition systems accept this signal directly. - Page 5 Global Water 800-876-1172 globalw.com connect the output wire (white wire) to a second input terminal on the logger in the same way as the level output. g. If the system only accepts voltage signals, the sensor output must be converted to a voltage signal by reading the voltage across a precision resistor in series with the signal wire.
