precision bridge isolation and measurement amplifier circuit

Published:2011/5/15 1:04:00 Author:John | Keyword: isolation and measurement amplifier circuit, precision bridge

Bridge isolation and measurement amplifier circuit is widely used for industrial process control, which is composed of ISO102 and INA102 with low noise and low power comsuption. Just as shown in the figure. ISO102 is capacitor coupled buffer and isolation amplifier circuit, having a gain of 1000. It is mainly used for 300Ω bridge signal amplification. The power supply of a bridge is completed by the two parts. One is that the supply side(INA102 12 feet) provides l4mA current through the 680Ω resistor, the other is that the +5 V reference from the ISO102 incentive provides 2.7mA current. The plused 16.7mA current powers the bridge. Changing signal of the bridge can be directly input to the differential input point of INA102. It can achieve isolation amplifier of both bridge signal and output voltage Uo. The measurement circuit is powered by PWS725A or PWS726A and other DC / DC conversion devices. So the implementation of no common ground and no total power supply can be achieved in isolated parts. The circuit can be directly used for accurate measurement of direct pressure, weight and physical strain and so on.   (View)

Current Detection Circuit Diagram made up of LM311 and Others

Published:2011/5/20 22:42:00 Author:leo | Keyword: Current Detection Circuit Diagram made up of LM311 and Others, LM311

As what is shown in the picture, this is a current detection circuit diagram which is made up of LM311 and others. In this circuit, when the input control signal of the screen grid VT1 is in high level, it will use VT1 as the current detector. When the armature of DC electro-motor is turning, the commutator lug of brush shorts suddenly, which generates current pulses. The current pulses come through RDS of VT1 and are changed to voltage signals. Then the voltage signals are AC-coupled when passing through capacitor C1 and reach non inverting input port of comparison unit. C2 is used as filter which can make A1 output smooth wave shape that can be used in combination with pin 5 and pin6 to sharp the edge outputted by clock.   (View)
