Sensors of this type that I know of, already has an amplifier built into the sensor. Processing ultrasonic pulses to (analog / proximity digital out) measurements is a special field. It can keep you very busy that you miss the goals of your original project. The sensor with built-in amplifier gives out (as example) an analog signal such as 0 to 10V. The S7-1200 does have analog inputs on-board the CPU. This will be your best option. |
