The accuracy of a 4-20 mA transmitter depends on the integrity of its current-loop path, which must be free of shunt paths and ground loops, both within the transmitter and external to it. External to ...

The MAX12900 ultra-low-power, highly integrated 4–20-mA sensor transmitter from Maxim Integrated Products has a 10-ppm/°C voltage reference for up to 3.5 times lower drift compared to traditional ...

Sealevel Systems, Inc. adds a new 4-20 mA current loop board to the SeaRAQ family of I/O expansion designed for Relio industrial computers. Sealevel Systems, Inc. adds a new 4-20 mA current loop board ...

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 ...

The XTR105, XTR112, and XTR114 from Burr-Brown are a family of two-wire, 4-20 mA current-loop transmitters with instrumentation-amplifier input stages. The front end is designed to be used with a ...

The I/O capabilities built into most microcontrollers make it easy to measure the analog world. Say you want to build a data logger for temperature. All you need to do is get some kind of sensor that ...
