DPI 314 Engine Pressure Ratio test set 

For applications where a ground test instrument is required to verify the Engine Pressure Ratio (EPR) transmitter on aero gas turbines, the DPI 314 provides the test capability. Housed in a rugged portable case the instrument provides both digital display of the inlet and exhaust pressures, the EPR ratio and the current time and additionally a pressure and vacuum generation system. The user can apply the desired inlet pressures to the transmitter and then the exhaust value, the resulting EPR being computed and displayed to allow calibration of the installed EPR sensor.
