The HCPL-4100 isolated 20 mA currrent loop transmitter is designed to operate as a transmitter in equipment using the 20 mA current loop. 20 mA current loop systems conventionally signal a logic high ...

Significant efficiency and performance improvements can be realized by improving the current loop’s power supplies, replacing linear regulators with high-efficiency buck regulators. It also increases ...

To complement the 2-wire and 3-wire sensor transmitter blogs that Kevin Duke and I have already published on Precision Hub, my next few blog topics will be on 4-wire sensor transmitters. The blogs ...

The Loop-Powered Transmitter (LPT) from Otek Corp. extracts power from the loop’s current and uses it to charge a supercapacitor that powers the RF transmitter. The Loop-Powered Transmitter (LPT) ...

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 ...

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, ...

Many instrumentation and control applications use analogue current loops as the physical links for telemetry measurements and remote actuator control. Most popular is the 4 to 20mA standard, in which ...

In order to fulfill the need for economical displacement transmitters with simplified installation, Brüel & Kjær Vibro (B&K Vibro) announces the release of the DT-12x series of transmitters. These ...

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 ...
