This application note’s primary goal is to provide an easy-to-understand primer for users who are not familiar with 4-20mA current-loops and their applications. Some of the many topics discussed ...

Transmitters are available with either floating outputs (typically used in loop-powered applications) or with single-ended outputs (typically used in locally-powered applications). This application ...

Open-loop current sensors have a definite price advantage over closed-loop counterparts. While you can use them in drive applications where torque accuracy isn't demanding — such as pump and fan ...

Instrument loop problems are frustrating at the best of times and can be really time consuming affairs to deal with. Most of the time these problems are related to isolation and ground faults.
