My company makes a level sensing device that consists of a microcontroller board and a pressure transducer. The pressure transducer output ranges from 0.5 to 4.5VDC. The micro samples this line and sends the answer (10 bit number between 100 and 923) and from this and the density we figure out the height and ultimately the volume. The cable between the micro and the transducer has 3 conductors (Ground, 5VDC supply, and the output). Does this application call for shielded cable? A client has used unshielded cable in many installs with no problems but some erratic behavior from one unit is making me wonder.
