To complement the 2-wire and 3-wire sensor transmitter blogs that Kevin Duke and I have already published on Precision Hub, my next few blog topics will be on 4-wire sensor transmitters. The blogs ...

The HCPL-4100 isolated 20 mA currrent loop transmitter is designed to operate as a transmitter in equipment using the 20 mA current loop. 20 mA current loop systems conventionally signal a logic high ...

Many instrumentation and control applications use analogue current loops as the physical links for telemetry measurements and remote actuator control. Most popular is the 4 to 20mA standard, in which ...

The accurate transmission of analog signals over long distances in noisy industrial environments is a difficult design problem. One of the oldest solutionsisolated current loopsis still one of the ...
