Using Ceraphire ceramic sensor in pressure sensor modules, Deltabar FMD71 calculates differential pressure (DP) from 2 pressure sensor modules, each connected electronically to single transmitter, and transmits level, volume, or mass via 4–20 mA with HART as standard 2-wire, loop-powered device. Electronic system eliminates issues associated with impulse lines or capillaries, such as icing, clogging, leaks, condensation, and changing ambient temperatures.
