Product Overview

The German K.K DA303 thick-range probe is a high-performance accessory designed for ultrasonic thickness gauges, specifically developed for measuring thick materials in industrial applications. With its 2MHz low-frequency design, the probe can effectively penetrate metals and other ultrasonic conductive materials ranging from 5.0mm to 300mm, making it particularly suitable for wall thickness monitoring of pipelines, pressure vessels and other large industrial equipment. The 16.2mm diameter contact surface ensures optimal coupling and measurement stability, while its operating temperature range of -20℃ to 60℃ meets requirements for standard industrial environments.146

Technical Features

The DA303 probe incorporates optimized acoustic structure design with excellent penetration capability and signal stability, providing accurate thickness measurements for various metals including carbon steel, stainless steel and aluminum. Its low-frequency characteristic makes it particularly effective for materials with significant sound wave attenuation such as castings or coarse-grained materials. The probe features standard DA231 cable interface and is compatible with multiple mainstream thickness gauges including K.K DM4 and DM5 series, supporting automatic probe recognition and zero calibration. The wide-band design effectively minimizes the impact of surface roughness on measurement results, and when used with high-temperature couplant, enables thickness measurement through surface coatings.2715

Application Scenarios

This probe is widely used in equipment maintenance inspection across petroleum chemical, power energy and shipbuilding industries, especially for periodic wall thickness monitoring of critical equipment like refinery pipelines, boiler pressure vessels and storage tanks. In corrosion inspection, it can accurately identify remaining wall thickness after corrosion, providing data support for preventive maintenance. It s also applicable for thickness quality control of large forgings, rollers in mechanical manufacturing, as well as safety evaluation of steel structures in construction industry. The rugged housing design adapts to complex industrial field conditions.61218

Operating Instructions

Special couplant should be used to ensure effective sound wave transmission during measurement. Clean measurement surface to remove oxide layers and impurities before testing. For high-temperature surfaces, high-temperature couplant is recommended with controlled contact duration. Built-in damping material effectively suppresses noise interference for clear echo signals. Regular inspection of probe wear condition is advised, and probe status should be checked when abnormal measurement fluctuations occur. This product is not designed for continuous operation in extreme high-temperature or highly corrosive environments.91720
