This design will interest technicians who work on pneumatically operated valves and other 4-20mA current loop controlled devices. Although 4-20mA signal injector/calibrators are available, this one is ...

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 ...

Analog Devices has designed a high-resolution data acquisition chip for 4-20mA current loops around an ARM Cortex-M3 core. Called ADuCM360, the chip includes dual 4ksample/s 24-bit sigma-delta DACs ...

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, ...

To reduce noise and voltage drops in analog voltage signals, the market place has adopted an analog current (4-20mA) output as its sensor signaling standard. A very robust signal, 4-20mA current ...

National Semiconductor's new DAC161P997 16bit d/a converter features a single wire interface and 4 to 20mA current loop drive and is designed to simplify the design of smart transmitters used in ...

Imagine this scenario: There is a flow meter with 4–20 mA output setup. The switch is flipped, thereby turning it on. Then it is noted that the readings are off, and the required output is not shown.
