The new 4020LT-A corrosion transmitter from Cosasco

The new Model 4020LT-A two-wire transmitter from Cosasco provides enhanced resolution measurements of metal loss due to corrosion inside pipelines.

The new transmitter is compliant with all CE, ATEX and IECEx standards, and designed for operation in plant locations with widely separated monitoring points and a preexisting distributed control system.

While similar products only have resolutions of 0.4 per cent, the Model 4020LT-A features measurement resolution to plus or minus0.1 per cent, 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(R) 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.

Rohrback Cosasco Systems (a Halma company) specialises in a complete range of corrosion management and monitoring solutions. Consasco equipment is used for a range of monitoring applications, including internal corrosion, atmospheric, remote, downhole corrosion, rouge, erosion, and scale in water.
