Loop-powered differential pressure and flow transmitters, for environmentally harsh applications, feature a two-wire, 4- to 20-mA output, 9- to 35-Vdc input voltage, and come with or without a dial gage. Three or four-wire, 0- to 5-Vdc output versions are also available. They have 2% FS accuracy; 0- to 5-in. H2O to 0- to 1000-psid differential pressure ranges, and 0-1 to 0-10-gpm flow ranges.
