I've got a torque transducer which gives 2mv/v output, i need connect the transducer to a Siemens PLC, can any one helps me with design a amplifier and tell me why i need that for interface the transducer with PLC?
What is the maximum output of the torque transducer and what is the full-scale input voltage of the PLC? That will determine the required amplifier gain (if any).
