The transmitter is compliant with all CE, ATEX and IECEx standards, and designed for operation in plant locations with widely separated monitoring points and a pre-existing distributed control system.
While similar products only have resolutions of 0.4%, the Model 4020LT-A features measurement resolution to ±0.1%, allowing a timely response to corrosion rate spikes.
The transmitter has an available NEMA 4x rated stainless steel enclosure for reliable operation in harsh environments. A switchable probe type selector allows users to easily adjust between different Corrosometer 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 to USA, Canadian and European standards.
