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 ...

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. Related To: Sealevel Systems Inc. Sealevel Systems, Inc.

I recently published a simple design for a platinum resistance detector (PRTD) 4 to 20mA transmitter circuit, illustrated in Figure 1. Unfortunately, implementing such quadratic floating-point ...

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 ...

NORWALK, CT / ACCESSWIRE / March 15, 2023 / Omega's newest RTDs, the PRTXI and the PRTXS Series, offer more configuration and higher temperature ranges than other RTDs on the market. These innovative ...

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 ...

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.
