The Model 4020LT-A two-wire transmitter (photo) provides enhanced resolution measurements of metal loss due to corrosion inside pipelines. The new transmitter is designed for operation in plant locations with widely separated monitoring points and a preexisting distributed control system (DCS). According to the company, similar products only have resolutions of 0.4%, while the Model 4020LT-A features measurement resolution of±0.1%. A switchable probe-type selector allows users to easily adjust between different electrical resistance probe types. The unit provides isolation between the probe and the 4–20-mA circuits required to power the loop, making it intrinsically safe. — Rohrback Cosasco Systems, Inc., Sante Fe Springs, Calif.
