The majority of applications utilize a simple 0-10v signal which can be converted into a pressure using a simple equation. This is available on all our active gauges. However, some industrial industries still favor the 4-20mA output, therefore the DI/DU gauge, which is firmly aimed at heavy industrial applications, has a 4-20mA variant.
However, with the increase of data collection, more digital communication protocols are becoming common directly on the gauge head itself, instead of via a hub converter. These include RS232/RS485, EtherCAT, Profibus, Ethernet IP, and the list goes on.
