Hi, good afternoon, I am an Electronics Engineer specializing in Applied electronics and Circuit design. I have designed systems using the LM331 before like highly interference immune transceivers and level-to-pitch converters. furthermore, I am familiar with the 4-20mA current loop communication scheme. I propose using an op-amp-based, trans-impedance amplifier to convert the current loop signal into a suitable voltage level, then filter, offset shift and gain shift the signal, and finally, feed it to the LM331 or similar converter. Of course, many design details need (and will) to be solved, take this only as a high-level proposal. I detail my previous experience related to the project: * 4-20mA signaling scheme. * General sensitive Analog circuitry design and simulation, using Spice-based tools, such as PSpice, NGSpice and LTSpice. * Signal transceivers, noise and EMI rejection. Filtering. * Control loop design, simulation, and calculation. Please get in touch with me to discuss this further, I can guarantee first-class work, offering unlimited reviews until you are delighted with the final job. Regards,
