The Hot-Wire Anemometer/Anemometr Z Grzanym Włóknem
This study analyses the behaviour of a hot-wire anemometer incorporated into a bridge circuit in the function of the voltage U z supplying the bridge circuit and hence the current I w flowing through the hot wire. The dependence of differential voltage Δ U on I w and the value of derivative d (Δ U )/ dI w as a function of the current supplying the hot-wire element were determined. These data enable the determination of working conditions of the constant-resistance (i.e. the constant-temperature) hot-wire anemometer.
THE INVENTION CONCERNS A CONTROL CIRCUIT FOR ANAEROBIC REACTOR SYSTEM. THE TOUR INCLUDES FILTER 16 ESTIMATE THAT RECEIVES INPUT SIGNAL SENSOR PRODUCTS AN ESTIMATE OF THE PRESENT VALUE A VARIABLE IN THE SYSTEM, COMPARE THAT ESTIMATE FOR A SIGNAL SENSOR THE VARIABLE AND PRODUCT OF THAT COMPARISON, SIGNAL ERROR dIFFERENCE IS TO COMBINE THE RECEIVED SIGNAL and reapplied INTEGRATOR, A DISPOSAL OF A BIAS LONG TERM THAT MAY BE PRESENT IN AT LEAST ONE OF SIGNALS rECEIVED, SUCH ELIMINATOR INCLUDING HIGH PASS FILTER BY 53 OR rECEIVED INPUT SIGNALS ARE TRANSMITTED TO THE iNTEGRATOR 58, SUCH FILTER HIGH PASS THAT REJECTING THE BIAS PERSISTS FOR A PERIOD CONSIDERABLY LONGER THAN THE TIME cONSTANT SYSTEM. APPLY THE iNVENTION INCLUDING THE TREATMENT OF WASTE WATER.
