Butterfield, MN | I can tell you from looking at some old SCS 440 diagrams that the -059 part number is the old one and it was replaced by the -090 part number a number of years ago. I'm pretty sure that they are functionally the same. They have a working range of 1-5 volts for full range, 1 volt is 0 PSI and 5 is 250 PSI I think, so you have to do the math to figure out how much voltage change makes up 1 PSI. Maybe someone can correct me if 250 isn't the max PSI, but I'm pretty sure about the voltage range. | |
