Dakota PMX4-DL High Penetration Thickness Gauge

Overview

The Dakota PMX4-DL High Penetration Thickness Gauge is engineered specifically to measure materials that present challenges for traditional ultrasonic thickness instruments due to poor sound penetration. These materials often have inconsistent grain structure, high density, or composite makeup, making accurate thickness measurement difficult without optimized ultrasonic pulsing and filtering. 

Unlike conventional thickness gauges, the PMX4-DL includes customizable high voltage pulser options and filters tuned for low frequency transducers, enabling deeper penetration into materials such as fiberglass, carbon fiber, cast metals, rubber, and various plastics. This expanded capability makes the Dakota PMX4-DL a dependable choice for industrial inspection of hard-to-measure substrates where conventional ultrasonic instruments may fail. 

The gauge’s advanced electronic platform—FPGA driven for enhanced responsiveness—and high screen refresh rate improve overall measurement performance and responsiveness in complex inspection conditions. These features, combined with intuitive user controls and rugged construction, support inspection teams in industrial environments where precision and reliability are critical.
