THE ELECTRICAL CALORIMETER AS AN INTEGRATING DEVICE,
Abstract
The immediate interest in an electrical calorimeter was in its data averging feature. Studies with experimental calorimeters designed for use with wave sensors in measuring the average energy of ocean waves indicate that measurement intervals even longer than the desired 20 minutes can be achieved. The fact that the readout is a direct measure of the average of the mean square of the input signal (over an interval of time) makes the basic calorimeter readily applicable to the telemetry of ocean-wave measurements for which it was developed. By substituting thermistors, which do not have a linear response to input power, for the wire windings or by the incorporation of the calorimeter into a more sophisticated calorimeter circuit, mathematical processes other than squaring and integrating are possible.
