Over long cable runs, an isolated 4-to-20-mA current loop offers robust noise immunity and tolerance. This characteristic makes it popular for analog data transmission in noisy industrial and ...

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 ...

In current loop systems, a transducer monitoring some process variable — temperature, pressure, flow, etc. — is connected to a transmitter.

Tucson, Ariz. – A programmable 4- to 20-milliamp current loop transmitter from Texas Instruments Inc.'s BurrBrown product line provides for digital calibration of sensor and transmitter errors, thus ...

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.

Figure 1: This loop-powered 4-20 mA transmitter features PWM drive and galvanic isolation from the input signal. (Click on image to enlarge) The external PWM-encoded signal is a rectangular waveform ...

These fully integrated, loop-powered displacement transmitters offer a unique streamlined solution for shaft displacement and vibration monitoring capability for a wide range of industrial machines.

The firm has a more detailed description of the precision current interface on line in a paper titled “ High-Performance, High-Accuracy 4-20mA Current-Loop Transmitter Meets Toughest Industrial ...
