I have a setra pressure transducer with 3-wire connection
1) +EXC - need to connect to power supply
2) COM - negative for power supply and multimeter
3) -OUT - need to connect to multimeter
Connection need to be made as shown in picture
Its voltage input requirement is 12 - 30 VDC. Is there any NI module I can use to connect all three or two different module?
Also, I have NI 9870 module. Can I use that? and if yes how?
Thank you in advance
No, you can't use the 9870 , but maybe the supply and the rack...
However, you didn't provided the type of the sensor (or to be kind, a link to the datasheet 😉 )
So we don't know the type and range of the output and how fast you need to read it?
Thank You Henry,
below is link to data sheet:
Setra267 is Low differential pressure transducer. If you can suggest any module which I can use that will be great. I am new to NI system so not much familiar with it,
Thank you again.
That sensor has an analog current output 4-20mA (industrial standard)and is used for (quasi) static measurements.
We don't know about the existing modul/s racks... (somehow the C-module you mentioned is connected to the computer, and you might (re) use that.
so the modul only could start with a ni 9203 (8 current channels)
or you might choose a more versatile module that can measure current and voltage and other type of sensors (future use?)
ni 9218 ? the 9218 needs a certain adapter to measure 20mA ..
Anyway, I recommend to talk to an NI sales/application person
If you look for a cheap, but not so accurate solution, there are other possible ways to go, but by your questions a wire,plug and pray solution is what you look for 😄
The sensor datasheet mentions that the sensor calibration is done with a 24V supply, so depending on your needs, a 24v supply is a good idea.
