XTR101 ELectrlcal Bridge InPut, Voltage Excitation Circuit
As shown, this circuit uses the voltage regulator tube LM129 to generate a 6.9V voltage reference, andthe 6.9V voltage reference provides 1.0147mA current to the electrical bridge. The electrical bridge could be variable resistance bridge type sensors like the pressure sensor etc.
