Automatical wiper control system circuit diagram

Published:2011/5/9 20:48:00 Author:Nicole | Keyword: aAutomatical wiper, control system

It is a automatical wiper control system circuit diagram, when the rain drops to sensor, its internal will produce voltage(A point) change which changes in relation to the rain intensity and frequency(in piezoelectric element, the voltage waveform is proportional to the rain drop energy), this voltage waveform is amplified by sensor internal amplifier circuit(B point), it is stored in power amplifier charge circuit. When the voltage singal of storing charge circuit reaches a definite value(V0), it is imported into wiper dirve circuit by comparing circuit, then the wiper starts to work. The interval time(T) is proportional to the speed 14 of charge circuit voltage, so the wiper's energy is higher, the car speed is quicker, so the time is shorter; on the contrary, the time is longer.   (View)

Strain bridge current transmitter circuit diagram composed of XTR115 precision current transmitter

Published:2011/5/6 2:47:00 Author:Ecco | Keyword: Strain bridge, current transmitter , precision

Strain bridge current transmitter circuit composed of XTR115 is shown as the chart. Pin 3 will be regarded as public place, pin 1 will provide +2.5 V power supply to the strain bridge. Pre-amplifier uses TL061 single op amp (also uses OPA2277 dual op amp, only one op amp), the +5 V regulator will provide power the op amp by itself. R1 is 20kΩ input resistor, C is the noise reduction capacitor, VT is the external NPN power transistor, which can select 2N4922, TIP29C, TIP31B models. it set 2N4922 as an example, the main parameters UCEO = 60V, ICM = 1A, PCM = 30W. The circuit working principle: when the force is on the specimen, the voltage signal output by strain bridge firstly passes through the pre-amplifier and changes into the 0.8 ~ 4V input voltage UI, and then it is input current of 40μA ~ 200μA II converted by the RI, at last it will be amplified 100 times by the XTR115 and obtains 4 ~ 20mA current.   (View)

Electric Heaters Like Electric Iron Current-limiting Thermostatic Circuit

Published:2011/5/7 2:16:00 Author:Joyce | Keyword: Electric Heaters, Like Electric Iron, Current-limiting, Thermostatic

Some electric heaters in daily use likeelectric iron would not only waste a large amount of electric energy ,but burn out electrothermal cores because of long time operation. If we connect a diode to the electric circuit, the current will be limited by the power,which is supplied by the diode half-wave rectification when the electric appliance pauses to operate. In this way,the voltage of the electric appliance would decrease by 50%,and the electric appliance would keep in a preheated state. Once the K in the graph is closed when in use, the electric appliance will function properly with a full load input. The connection of components is shown in the graph.
