Sensor signal conditioner circuit  with multi-functional 0 to  30 mV AD693 unipolar input-4 to 20mA output circuit 1

 

The circuit components are used AD693
Constituted by the AD693 unipolar 0 ~ +30 mV input, 4 ~ 20mA output circuit as shown. Circle Power Us The allowed range +12 ~ +36 V. RL is the load current loop resistance, ILOOP for the loop current. Add to AD693 on the actual supply voltage (Uop) asuse local power, +6.2 V reference voltage source and to be connected between the 6.2kO resistor, the voltage reference of the load current is set to 1mA. C for the power supply decoupling capacitors.
