Micrlogix 1400
spectrum controls 1762sc-IF8u analog input card
Dwyer 628CR-10-GH-P1-E4-S1 0-100 PSI 4-20 Ma
We are putting transducers on each side of pumps that draw ink out of tanks and keep a supply lines pressurized. The sensor between the tank and the pump usually has a negative pressure on the gauge there and they can use that value to tell how clogged the filter is which is also behind sensor. It has a positive value at times depending how full the tank is which is above the pump.
not sure how to properly scale this because of the negative values.
