Tracking down cable cuts and differentiating them from normal open circuits is critical. Flexibly evolving the circuit design ...
The humble 4 to 20mA current loop has been a faithful servant of process control systems for decades, largely down to its reliability and simplicity. The underlying principles of the current loop are ...
My recent DI contribution (Another silly simple precision 0/20mA to 4/20mA converter) used the LM337 regulator in a novel circuit arrangement to translate an input 0-20 mA current source into a 4-20 ...
With an eye on factory automation, Maxim has released a reference design for a precision 4-20mA temperature transmitter with added data capability. The whole thing, branded Novato, is loop-powered, ...
A whitepaper that explains the proper way to use and install transmiters in a current loop is now available from Acromag. As the leading analog transmission standard for industrial I/O, the future ...
NewTek Sensor Solutions of New Jersey is offering hermetically-sealed LVDT position sensors with a 4 – 20mA current loop output. “Sustaining accuracy with no errors over long distance transmissions, 4 ...
