Applus RTD’s Plant Master is a permanently installed monitoring system based on ultrasound. It provides continuous measurements of wall thickness in critical and hard-to-access components in refineries, chemical plants, power plants, and offshore facilities. Using high-temperature piezo-ceramics, sensors are applied to ultrathin foils. Permanently dry-coupled directly to the surface of a component, the flexible ultrasonic transducers are then used for single-point pulse-echo measurements of the component’s wall thickness. The sensors continuously operate at optimum performance for years at temperatures of up to 200°C (390°F), thus allowing the inspection of high-temperature components.
