Can multiple transducer be handled by single datalogger

[zeeextra]

I have 3 presure guages generating 0-20mA analog signal and one differential pressure transducer also generating 0-20 mA signal. I need to maintain a log of all pressure readings. In this regard I need to have a datalogger which can translate my analog signal into digital format so that Labview will display and maintain record.

In this regard I would like to ask that do I need to buy only 1 datalogger or 4 dataloggers for all the pressure devices.

Sorry if I ask very basic question but I am far away from the field of electronics/instrumentaion.

Most NI data acquisition devices are multichannel and you would only need to buy 1. The least expensive is the 6008. With 4 differential inputs, it just meet that need.
