A closed loop measuring system includes a digital computer, a measurement device, actuator means associated with the measurement device, and controlled by the computer for establishing known and unknown conditions of a physical phenomena such as pressure, torque, or temperature in the measurement device, and the sensors associated with the measurement device responsive to the conditions established therein for producing relative data values which are stored in the computer memory. The computer controls the establishment of the known and unknown conditions in the measurement apparatus and the storing of the relative data values, and calculates the unknown conditions from the stored relative data values and the stored values for the known conditions. Measurement apparatus for use in such systems, includes a water manometer for measuring gas pressure, a mercury manometer for measuring gas pressure, a torque transducer for measuring torque loads, and a temperature transducer for measuring temperature.
