Hi, I have what I consider a simple project, but am having a bit of trouble understanding the basics. All I want to do to read the signal from a hydraulic pressure transmitter (such as, SETRA C206 Pressure Transmitter 24VDC, 0-7500 PSIG, 4-20mA) and display it on a load cell digital indicator. This is to use it as a scale on an industrial loader.
All the load cell displays I've seen can drive 1 or more 350Ω load cells, but the pressure transducers seem to be 800Ω. Is it possible to 'plug' a pressure transmitter into a load cell display and get it to work? The reason why I want to use a load cell display is because they're cheap on eBay, less than $100(and less than $100 for the pressure transmitter), whereas complete loader scales are $700 and up.
I'm just a dumb farmer and while I can happily plant and grow a couple of thousand tonnes of wheat, lupins, canola, etc. I just get lost when I try to work out electronics! It frustrates me that this would seem to be a simple problem for someone with probably basic knowledge, but it's beyond me.
Any help would be greatly appreciated. Even if someone can just explain the Ohm difference between the 2 and what it affects.
Thanks
ps. Yeh, it's taken me 5 years to make my first post. You can't rush these things you know..... ;-)
