How to connect a Yokogawa transmitter in two-wire configuration to a three-wire measuring instrument
Thread Content
Here’s the situation: we have existing Yokogawa transmitters that are now ready to be sent for testing. However, these transmitters use a two-wire connection system, while the testing equipment requires a three-wire connection. The question is, how can we connect the Yokogawa transmitters to the testing equipment?

I’m afraid it won’t connect… A three-wire system can be connected to a four-wire gauge, but a two-wire gauge probably can’t be connected.
Your description isn’t very clear; please provide the specific models of the transmitters and measuring instruments so that we can determine the appropriate solution.
First, let’s take a look at how the input signal flows into the detector
Measuring current involves a simple series circuit, while measuring voltage involves a parallel circuit – something that middle school students already know....
