Transmitter accurately transfers voltage input: 05/15/03
EDN-Design Ideas / When you connect remote sensors to a
central process controller, a simple, robust, and commonly used
interface is the 4 to 20-mA loop. The advantages of this current
loop include the simplicity of just two twisted wires that share
both power and signal, the loop's high noise immunity in harsh
environments, and the de facto loop standard within the
process-control industry... |
