A transducer assembly for measuring effective teat load exerted by the liner during machine milking was developed. The transducer yields a linear relation between applied liner load and analog voltage output. Measurements with an artificial teat for five different liner designs were found to only marginally reflect measurements with cow teats. Measurements at two circumferential and two longitudinal positions were made. Results showed the liner to significantly reduce vacuum loading over a majority of the teat. These measurements are useful to quantify evaluation of linear designs and for companion studies to determine teat tissue stresses during milking.
