Supply voltage compensation is important to keep the accuracy for hot wire/hot film gas flow sensors. A compensation experiment device is established, the two steps curve fitting is presented to determine the functional relations among flow、sensor output and supply voltage, the coefficient of fitting polynomial is determined by Least Square method, thus eliminating the influence of supply volta...
The ease and convenience of a hot-wire cutter for the separation of wells from PVC radioimmunoassay trays has been demonstrated.' In constructing a similar apparatus, it was felt that a worthwhile simplification could be achieved by arranging to push the PVC tray past a fixed hot wire. The wire can simply be held under spring tension, and the springloaded telescopic arm previously employed' be ...
