M
I'm looking for 1 of 2 things either a 0-5 psi pressure sensor that puts out 20 ma at o psi and 4 ma at 5 psi or a 4-20 ma signal reverser-inverter that would take the 4-20ma and change it to 20-4 ma. this signal is to control a pump that requires 20ma for full speed and modulates to low at 4 ma.
thank you
