Smart 4-20ma transmitter The old-fashioned way to build a 4-20mA transmitter included a field-mounted device that sensed a physical parameter and generated a proportional current in the standard range ...

The 4–20mA transmitter converts the digital input to the analog output over the current loop. The sensor used with Monterey is a platinum resistance temperature detector (PT1000). The entire system ...

But despite their popularity, two-wire transmitters and 4-20mA loops are often misapplied and many misconceptions exist. This white paper explains the proper way to use and install transmitters in a ...

Nowadays, system designers must develop enhanced 4-20mA sensor transmitters with several considerations in mind. These include improved measurement accuracy over a wide temperature range and ...

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, ...

4-20mA sensor transmitter from Maxim Maxim has launched a 4-20mA sensor transmitter for industrial automation applications The MAX12900 is for automation and process control, loop-powered 4-20mA ...

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 ...
