THE DYNAMIC BEHAVIOR OF THE CARBON HUMIDITY ELEMENT ML-476,
Abstract
Measurements of the step-function response of Carbon Humidity Element ML-476 taken at different environmental temperatures and with humidity steps of different magnitude are presented. The measurements were performed on a two-pressure system of high precision, with a test port modified to allow exposure of the elements under test to controlled humidity steps of negligible rise-time anywhere within the operating temperature range of the elements. The response characteristics obtained show a fast initial response followed by a slower drift to equilibrium. Mathematical models of second and third order for the response of the carbon element are given in a form which yields to the restoration of the input time function from the measured output of the humidity sensor.
