Looking for a voltage to pressure chart for a Intelipak's space pressure sensor.
Unit keeps alarming on space pressure sensor and reading is way high.
-Transducer and calibration solenoid are new.
-Swapped control boards with like unit.
-Calibration is at 0.200vdc.
-Input stays at 5.00vdc
-If I unplug the sensor harness from the board, it reads ok (0.350vdc), then slowly climbs
-Space pressure stays steady as the voltage rises
-I replaced all tubing, other then tubing into space
-What's weird is reading going negative when opening return panels? Actual reading stays pretty much the same.
