How a 4 20mA Transmitter Works Instrumentation Tools Example : Process variable indicates 50 m3 hr. Transmitter regulates output to 12mA in the loop as per the configured range and measured process variable and its equivalent voltage is 3 V DC which is measured by A D Converter which indicates 50% of Process Variable. Positive feedback A simple feedback loop is shown in the diagram. If the loop gain AB is positive, then a condition of positive or regenerative feedback exists. If the functions A and B are linear and AB is smaller than unity, then the overall system gain from the input to output is finite, but can be very large as AB approaches unity. In that case, it can be ... How to Get Started with a Microwave Radar Motion Sensor Here’s a simple but useful electronic circuit of an adaptive security light that you can build yourself.
