Products used in this application:
Proportion-Air can build a liquid pressure control assembly to control the pressure of oil in a fuel pump test. Our QB2 is used to pilot the liquid regulator with our DST transducer providing direct feedback to the QB2. This assembly provides accuracy up to +/-0.5%.
A QB2 receives a command signal from a PLC or controller equivalent to the air pressure required to open the diaphragm of the liquid non-venting regulator, allowing the desired amount of fluid oil pressure to pass through. The DST stainless steel pressure transducer is measuring the pressure of the fluid and is providing a second loop feedback to the QB2. The monitor signal can be connected to the PLC or digital panel meter to display the exact pressure going to the fuel pump.
