NI 6008, Measurement Computing usb-201

[Mulerine]

So i need daq module i choose this two as similar. Have anyone use USB-201 ? what are pros and cons, price is for sure the pros

and i have pressure transducer http://peltron.pl/wp-content/uploads/2015/04/NPC.pdf ( is in another language )

The power supply for output signal 0-10V   (the one i choose and USB-201 is for voltage input only) is 15÷30 V three wire so schematic on the left

So how should i connect transducer? the usv-201 is power by usb 5V 

i connect one wire in analog input in modeule and groud an powre transducer by external powwer suplay with voltage range 15÷30 V ?

First of all, here is the English manual: http://peltron.pl/en/produkty/npc/

The USB-201 and the NI USB-6008 both has a 12 bit ADC. It means if the usb module can be run in the 0-10 Volts range (check the spec sheet), it gives you a 10 Volts / 2^12 = 2.4 mV resolution. The pressure transducer states a full scale accuracy of 0.5% --> 50 mV. Therefore, the 12 bit ADC is enough in this case, either using the USB-201 or the NI product. Another important thing is that, the USB-201 is NOT an NI product. So it will not be shown in MAX by default, and you have to install drivers I guess from the manufacturer's website.

About the wiring: first make sure you have the 3-wire model, not the 2-wire one (the 3-wire model gives out voltage signal, the 2-wire current signal!). The usual way to connect such 3-wire voltage output sensor is to power the sensor between the ground (com) and the power input (+15-30 Volts DC voltage), and you can measure the signal between the signal wire (+) and the ground using your USB module.
