4-20 mA Current Loop Data Logger

4-20 mA current loop data loggers capture sensor and control data that vary current as a function of measured parameters. Measurements from process current loops are popular in many applications for load, pressure, torque and other mechanical parameters. DATAQ Instruments is an expert in data loggers for process current data applications, and offers a wide range of product solutions for any application. 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.)
