Rohrback Cosasco Introduces 4020LT-A Transmitter

The Model 4020LT-A two-wire transmitter provides enhanced resolution measurements of metal loss due to corrosion inside pipelines. Compliant with all CE, ATEX and IECEx standards, it is designed for operation in plant locations with widely separated monitoring points and a preexisting distributed control system. Measurement resolution to ±0.1% allows a timely response to corrosion rate spikes. It has an available NEMA 4X-rated stainless-steel enclosure for operation in harsh environments. A switchable probe-type selector allows users to easily adjust between different Corrosometer electrical resistance probe types. Isolation between the probe and the 4–20-mA circuits required to power the loop make it intrinsically safe.
