Intrinsically safe explosion-proof electromagnetic ultrasonic thickness probes measure wall thickness in explosive atmospheres. They use electromagnetic acoustic transducers to generate ultrasonic waves directly in conductive metal. This method needs no couplant, reduces surface preparation, and allows fast inspection on painted, coated, or rough steel.

In oil refineries, chemical plants, offshore platforms, gas pipelines, and fuel depots, small electrical energy can ignite flammable gas or dust. An intrinsically safe explosion-proof design limits voltage, current, and stored energy. Certified to ATEX and IECEx, the probe can be used in Zone 0, Zone 1, or Zone 2 hazardous areas with an approved barrier or isolator.

The probe measures remaining wall thickness of pipes, tanks, pressure vessels, and structural steel. It detects corrosion, erosion, pitting, and hidden metal loss before leaks occur. Real-time readings improve asset integrity, maintenance planning, and safety compliance. Operators can inspect hot or inaccessible points with less downtime.

Key features include rugged stainless steel housing, high-temperature tolerance, stable signal output, low power consumption, and simple connectivity to portable gauges or data loggers. Intrinsic safety lowers ignition risk without heavy explosion-proof enclosures, making the probe lighter and easier to carry. It supports safer, longer-lasting assets in hazardous areas. Regular monitoring improves safety and reliability.
