Rosemount 4390 Series Corrosion and Erosion Wireless Transmitters

Description

The Rosemount 4390 series provides continuous, high-sensitivity metal loss and corrosion monitoring for critical pipelines, refineries, and offshore production assets. By delivering continuous wall-loss telemetry directly to asset management systems, it eliminates dangerous manual field walkdowns. TPT24 supplies genuine Emerson process integrity solutions with verified documentation and rapid worldwide logistics.

Continuous Metal Loss Tracking with Rosemount 4390 Architecture

Internal corrosion and particulate erosion can cause catastrophic pipe failures if undetected. The Rosemount 4390 transmitter family continuously captures Electrical Resistance (ER) and Linear Polarization Resistance (LPR) measurements with 24-bit internal precision. Plant operators receive both raw sensor curves and calculated corrosion velocity trends, enabling rapid chemical inhibitor adjustments.

Versatile Probe Compatibility and Remote Mounting

Unlike rigid direct-mount instruments, this series accommodates remote probe cables up to 20 meters in length. This flexibility allows engineers to install probes in tight, high-vibration pipe racks while positioning the transmitter antenna in an unobstructed location for optimal WirelessHART transmission. The device effortlessly integrates with multi-element sand erosion probes as well as standard industry corrosion probes.

Rugged Field Reliability in Hazardous Environments

Engineered to withstand harsh ambient conditions from -40 °C to +70 °C, the Rosemount 4390 is certified for Zone 0 / Class I Div 1 intrinsically safe installations. Its advanced power management extends operating lifecycles by up to four times over previous transmitter generations, substantially reducing routine field maintenance overhead in remote facilities.
