4-20 mA Process Current Loop Data Acquisition

DATAQ Instruments offers a wide range of environmental 4-20 mA current loop data acquisition products for any application and budget. Choose from Ethernet or USB interfaces, and stand-alone or PC-connected configurations. Included software acquires, displays, reviews, and exports data with ease and without programming. Our hardware and software combinations take you from concept to results in minutes. Most products shown here are voltage mode input devices, but are easily converted to measure 4-20 mA with an inexpensive external shunt resistor that we sell as an accessory (model R250.) This application note shows you how: Learn more about 4-20mA current loop measurements.
