Application circuit of the ADT70 in the resistance strain instrument

Published:2011/7/8 5:45:00 Author:Christina | Keyword: Application circuit, resistance strain instrument

The application circuit of the ADT70 in the resistance strain instrument is as shown in the figure. The measuring bridge is composed of the temperature compensation chip R1, the measurement strain gauge chip R2, the no-sense line resistances R3 and R4. Their nominal values are 1kΩ. The operating current of the bridge channel is supplies by the IOUTA and IOUTB port, the current that flows through every bridge arm is 1mA. When there is no external force, you can adjust the bridge in balance. In this formula, the E is the bridge voltage. The △u is amplified by A1 and A2 to get the output voltage, and it is added to the DVM. The overall gain of the strain instrument and the calibration of the meter can be set by adjusting the resistance of R5, R6 and R7.   (View)

When braking, you should press the stop button STP, then AC contactor KMF (or KMR, KMF is forward contactor, KMR is the reverse contactor, 1SA, 2SA are the trip switches) loses power and releases, the motor M leaves from the AC power supply, and the normally closed contact KMF or KMR restores closed state, and KM coil gets electric and pulls in, and the main contacts close, then AC is added to the M stator windings by the main contact of KM and rectified into DC by the rectifier diodes VD1, VD2 to make motor brake quickly. At this time, due to KMF's (or KMR) normally open auxiliary contact is disconnected, the time relay KT coil is energized.   (View)
