A Practical Foil That Protects the Measuring Point
ABM75 covering material is an aluminum foil coated with kneadable putty that ensures fast and easy measuring point protection.
ABM75 aluminum foil with kneadable putty is an easy-to-use strain gauge covering material. The product consists of a 0.05 mm thick aluminum foil coated with 3 mm thick kneadable putty. ABM75 is simply pressed by hand onto the measuring point.
Especially when various substances can impact the measuring point (e.g. oil and water), it is recommended to use a combination of these covering materials. In these cases, the oil-soluble covering material should be directly applied to the strain gauge, since the aluminum foil serves as a diffusion barrier. The final layer should be an oil-resistant epoxy resin.
ABM75 covering material for strain gauges can be stored at room temperature for approximately 2 years.
