Thickness Measurements of Fiberglass Plates, Pipes and Storage Tanks


Ultrasonic thickness gages can be used for a variety of fiberglass applications, measuring parts from one side. Fiberglass storage tanks and pipes, for example, can be checked as part of the manufacturing process, and also in service to assure that no erosion or delamination from corrosive chemicals has resulted. Other applications include hot tubs, electronic circuit boards, coil bobbins, and sporting equipment. Ultrasonic gages can be used on many types of fiberglass: cloth, mat, roving, filament wound, or combinations of these.

Equipment: Fiberglass measurements are normally performed with gage models 38DL PLUS with the High Penetration software option, and 45MG with the High Penetration software. Transducer selection and setup depend on the desired thickness range capability and quality of the composite material. A typical measurement range would be from 0.050 to 3 in. (1.25 to 75 mm) using the specialized 0.5 MHz M2008 fiberglass transducer for thicker parts and other transducers such as the M1036 (2.25 MHz) or M109 (5 MHz) for thicknesses under 0.50 in. (12.5 mm).

Products used for this application


45MG

The handheld 45MG ultrasonic thickness gage is packed with measurement features and software options. This unique instrument is compatible with the complete range of Olympus dual element and single element transducers, making this gage an all-in-one solution for virtually every thickness gage application.

38DL PLUS

The 38DL PLUS is an advanced ultrasonic thickness gage. Uses dual element transducer for internal corrosion applications, and has features that include THRU-COAT technology and echo-to-echo. Uses single element transducers for very precise thickness measurements of thin, very thick, or multilayer materials.

Magna-Mike 8600

The Magna-Mike is a Hall effect thickness gage that uses a magnetic probe to perform accurate measurements on nonferrous and thin materials such as plastic bottles.
