Bench Test Results

This data is from bench tests characterizing the valves and the dynamics of the system.


Figure B1
Figure B1: Flow vs PWM. Two Clippard EV-P-10-25A0-V valves and Siargo flow sensor.


Figure B2

Figure B6
Figure B6: Closed-loop accuracy of calibrated SMC valve.


Figure B7
Figure B7: Open-loop transient response.


Figure B8

Figure B11
Figure B11: Flow to Pressure Regulation. Flow is regulated to 233mL/s until the pressure limit of 500mm H2O is reached. Then pressure is regulated.
