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 ...

Industrial temperature sensors are widely used with 4–20mA current-loop transmitters in industrial control and automation. In the current loop the temperature sensor converts a temperature into a ...

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 ...

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 ...

Current-mode control loops (particularly the popular 4- to 20-mA controls) are used in many industrial applications because of their immunity to induced EMI from motors, contactors, relays, and other ...

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, ...

Galvanically (that is, optically or electromagnetically) isolated 4- to 20-mA current loops offer robust noise immunity and tolerate long cable runs. These advantages, combined with simple unshielded ...
