signal, for the use of automated instrumentation, industrial temperature control. Here is 4mA as zero-scale value, 20mA full-scale value. REF193 is 3V reference voltage source, OP193 operational amplifier. RP1, RP2, respectively, and full scale calibration potentiometer zero, both can be adjusted independently of each other. VD1 Schottky diode, which prevents OP193 open loop voltage increases. Preferably the power supply voltage + 9 ~ + 18V. Transmitter output current expression is:
