Most circuits that require current loss detection use expensive isolation amplifiers. This circuit solves that problem with a simple and low-cost method to detect current loss of 4-20 mA.

Applications of Comparator The four comparators form a current detection circuit which can be used to indicate the four states of the input current, with resistors "Shunt" used to convert the ...

AFCI electronics function independently from thethermal and instantaneous sensing functions of the conventional circuit breaker. AFCI electronics detect current flow from the load terminals with ...

Schematic of TI surface bands and experimental concept. Transport measurements were also performed with the applied field and detector contact magnetization parallel/antiparallel to the current ...

Avago Technologies announced a new series of competitively priced isolation amplifiers with short circuit and overload detection. Based on optical ... Typical applications include inverter current ...

If the concept scales to actual conditions, the technique has the potential to reveal smuggled nuclear material that would pass unnoticed using current detection methods. It’s nearly impossible ...
