Corrosion is one of the primary causes of material degradation across industries, potentially leading to catastrophic failures if left unchecked. As industries around the world face challenges related to corrosion, accurate monitoring of material thickness is crucial to ensure safety, performance, and compliance with regulations. Whether it’s assessing pipelines, storage tanks, ships, or industrial equipment, a corrosion thickness gauge is an essential tool for identifying and managing corrosion risks. Cygnus Instruments, a renowned leader in the field of non-destructive testing (NDT), offers a wide range of corrosion thickness gauges, including ultrasonic and magnetic models, designed to provide accurate, reliable, and non-destructive measurements for diverse industrial applications.

Understanding Corrosion Thickness Gauges

A corrosion thickness gauge is used to measure the remaining thickness of materials that have been subject to corrosion or erosion. It helps detect thinning caused by corrosion, ensuring that infrastructure remains within safe operational limits. These gauges are used in industries where material integrity is crucial to safety and performance, such as oil and gas, construction, marine, manufacturing, and power generation.

Corrosion thickness gauges can measure the thickness of various materials, including metals, plastics, and coatings. Among the most popular types of corrosion thickness gauges are ultrasonic and magnetic gauges. Each type has its unique application, and Cygnus Instruments offers both to meet the diverse needs of professionals worldwide.

Ultrasonic Thickness Gauges: Precision for Tough Environments

Ultrasonic thickness gauges are among the most accurate tools for measuring the thickness of materials, especially in harsh or inaccessible environments. These devices use sound waves to determine material thickness. The gauge sends high-frequency sound waves through the material being measured. When the waves reach the back surface, they are reflected back to the sensor, and the time it takes for the waves to return is used to calculate the thickness.

One of the main advantages of ultrasonic thickness gauges is their ability to measure thickness from one side of the material, even when coatings or insulation are present. This feature makes ultrasonic gauges ideal for use in industries where materials are coated or insulated for corrosion protection, such as the oil and gas, petrochemical, and marine sectors.

Cygnus Instruments offers a range of high-quality ultrasonic thickness gauges, with models like the Cygnus 6+ and Cygnus 4+ leading the way in performance and reliability. These gauges are designed for tough environments, providing highly accurate results even in challenging conditions. For example, the Cygnus 6+ features advanced technology that can measure through coatings up to 20mm thick, which makes it especially useful for inspecting corrosion on pipelines and tanks without having to remove protective layers.

Key benefits of ultrasonic thickness gauges from Cygnus Instruments include:

• High Accuracy: Cygnus ultrasonic gauges offer exceptional precision, with measurements down to fractions of a millimetre.
• Non-Destructive: These gauges can measure material thickness without causing any damage, making them ideal for ongoing inspections without interrupting operations.
• Versatility: Suitable for a wide range of materials, including metals, plastics, and composites, ultrasonic gauges are used in many industries.
• Temperature Compensation: Cygnus gauges automatically adjust for temperature fluctuations, ensuring consistent results across varying environmental conditions.

Magnetic Thickness Gauges: Fast, Reliable & Cost-Effective

Magnetic thickness gauges are designed for a different purpose: measuring the thickness of non-ferrous coatings on ferrous metals. This includes applications such as measuring paint, galvanising, or other protective coatings applied to steel, iron, or other ferromagnetic materials. Magnetic gauges work by measuring the force of the magnetic field that passes through the coating and interacts with the underlying ferrous substrate. The greater the coating thickness, the weaker the magnetic field.

These gauges are known for their ease of use and speed. They provide fast, accurate readings and are ideal for quality control, routine inspections, and monitoring coating thickness in manufacturing, automotive, and construction industries.

Cygnus Instruments’ Cygnus 1 and Cygnus 2 magnetic thickness gauges are compact, portable, and designed to deliver reliable results in a range of industrial environments. The simplicity of operation, combined with robust performance, makes these gauges a top choice for professionals who require quick, accurate measurements on-site.
