The Servo Controller is used in conjunction with an Air-Flow sensor
, Air Cylinder and a properly designed and applied intermediate or unwind guide to accurately align the moving web of material.
The success story of the hot-film air-mass meter began in the 1970s with the introduction of the first air-flow sensor
, which worked according to the dynamic-pressure principle.
Based on the N[O.sub.x] sensor's signal, in combination with an engine mass air-flow sensor
and temperature sensor, the necessary urea dosing rate is calculated by the control algorithm.
The system uses an air-flow sensor
to detect the edge of the web, operating entirely on plant air.
One of them is a prototype of a patent-pending "mass air-flow sensor
" from D.R.
