How to connect a pressure transmitter and HART communicator
Hi. I have a question about HART communicators and devices. Can you help? How do I connect a pressure transmitter with a HART communicator? .
Expert’s answer: How to connect a pressure transmitter and HART communicator
Hi! Connecting a pressure transmitter and HART communicator? Then, let’s do this!
Transmitter connection – Pressure transmitters usually use current loops for power. That means you have 24 volts of direct current (VDC) in the same loop where you have 4-20 mA and HART. Now, to send data with the device in the workshop, you need a 24-VDC power supply, a 250-ohm resistor, and a handheld. Look at the diagram below to see how to install the device and connect the handheld.
In the field, you shouldn’t need the resistor because your cable resistance should suffice. But if it’s not enough for some reason, just use the same setup you had in the workshop.
