Radiodetection PCMx

Advanced Pipeline Current Mapper & Corrosion Control System

The Radiodetection PCMx is the industry-standard pipeline current mapping solution engineered specifically for pipeline integrity managers, corrosion engineers, and Cathodic Protection (CP) specialists. Designed to evaluate CP current distribution and locate pipeline coating defects, the PCMx enables rapid, non-destructive survey sweeps over long-distance buried steel pipelines.

Combining advanced electromagnetic signal processing with simultaneous AC Voltage Gradient (ACVG) capability, the PCMx identifies current loss points, holiday defects, and electrical contacts with secondary structures—ensuring compliance and extending asset life.

  • Simultaneous Surveys: Conduct Pipeline Current Mapping (PCM) and AC Voltage Gradient (ACVG) coating defect surveys in a single pass.

  • Long-Range Signal Propagation: High-power Tx-150 transmitter drives current up to 30 km (19 miles) along buried pipelines.

  • Automated Georeferencing: Integrated high-precision GPS/GNSS receiver automatically geotags every measurement trace for effortless GIS integration.

Precision Corrosion Diagnostics and Technical Specifications

Evaluating buried pipeline coating health historically required separate surveys and time-consuming manual measurement steps. The Radiodetection PCMx streamlines pipeline integrity workflows by capturing simultaneous current mapping (PCM) and AC Voltage Gradient (ACVG) data. Operators can trace pipeline paths, measure signal current magnitude and direction, and pinpoint coating faults concurrently.

  • Current Direction (CD) Indicator: Confirms target pipeline identity and detects signal return paths or current bleed-over onto adjacent metallic structures.

  • ACVG A-Frame Integration: Attaches directly to the PCMx receiver to pinpoint coating defects (holidays) down to precise centimeters.

  • Convertible Dual-Purpose Receiver: Removable magnetometer foot easily converts the unit into a full-featured RD8200-class precision utility locator.
