How To Power Multiple 4-20 mA Sensors

Data Logger > 4-20mA Process Current We’re often asked how to power multiple 4-20 mA sensors using a single power supply. While it is possible to do this, the usual cautions apply regarding ground loops and other subtleties. Readers who are┬ánew to measurements using sensors with 4-20 mA process current outputs should refer to our Read More

How To Determine 4-20 mA Loop Load

Data Acquisition > Current Process current (4-20 mA) measurements are popular with DATAQ Instruments’ customers, and that often leads to some interesting application questions. One of the better ones relates to how many process current instruments can be connected to a single current loop. Customers know that there MUST be a limit, but they’re not Read More
