Hi,
In my new project, i need to generate a current loop from ph sensor and transmit this to the main control board. I am using xtr117 for this purpose. Here i am providing loop supply from the control board itself. Will it enough to supply power to the xtr117 and other signal conditioning circuitry?.
The ph sensor reading is from -2000mV to +2000mV. so here i supply the 2000mV to the reference electrode of the ph sensor using the voltage reference ic and the potentiometer(the value may vary for different sensors). Also there is a gain adjustment at the opamp output.
Please find the attached schematics
Kindly comment on my design, waiting for a reply
