I do not know Drake. My under pressure on the low side protection and over pressure on the high side is all mechanical. I did not check into going electonic. By first glanced it looks like the cost would have been the same or less to go elec. I have enough ways to collect data and am not really interested in logging it. I have a Fluke logging thermometer and an elec meter so I know how it is performing and it will perform that way for yrs. to come.
