Abstract
A simple, new, triple-calibration scheme is developed for Goodrich (formerly Rosemount) model 0871FA ice detectors. The analog output voltage is equated not only to the usual liquid water concentration, but to accurately computed ice mass-and-depth accretion rates on the sensitive element of the detector. The three different calibration constants vary from detector to detector, but are related through invariant equations that are probe-independent. Thus, the relations can serve as universal calibration equations for any 0871FA detector. The method is demonstrated for three detectors in the steady-state conditions of an icing wind tunnel. Other observed characteristics of 0871FAs are described to help users understand the behavior of these detectors during operation
