Loop-powered differential pressure and flow transmitters feature twowire, 4- to 20-mA output. They come with or without a dial gauge, for local or redundant readout of pressure or flow. They have a 9- to 35-Vdc input voltage range, are offered with a standard three or four-wire, 0- to 5-Vdc output, and have 2% FS accuracy. Users can select from 0- to 5-in. H2O to 0- to 1000-psid differential pressure ranges and 0- to 1-gpm to 0- to 10-gpm flow ranges.
