Need to output 4 to 20 mA from Argon

Hardware

Hi guys,

I am new to electronics. I built a prototype external level sensor to measure the water level inside a closed, sealed tank. It attaches to the tank at two places, one near the bottom and one near the top. A float with a magnet travels up the PVC pipe sensor and trips Hall effect switches as it moves. The Argon scans the Hall array and interprets the position of the sensor and outputs to an LED internal to the electrical box and to a shielded twisted pair that outputs a 0 to 3.3 V analog signal.

The control system that I am connecting to would prefer a 4 to 20 mA signal to the 0 to 3.3 V that I am using now.

Does anyone know how to get a 4 to 20 mA signal from an Argon?

Thanks!

Chris
