DC Voltage and 4-20 mA Sensors

This is where you will find the equipment that connects sensors with DC voltage or 4-20 mA current outputs to a monitoring system. There are multichannel loggers with software-configurable inputs, compact Wi-Fi or Bluetooth loggers, Ethernet loggers that grow into a network, LoRaWAN loggers and the base station of a wireless sensor network.

The category also includes split-core current transformers, which convert a circuit’s current into a voltage signal, and a dissolved oxygen system with an analog output.
