Measuring Wheels

email: sales@impulseautomation.co.uk web: www.impulseautomation.co.uk Measuring Wheels APPLICATION In order to avoid errors when using mea- suring wheel actuation, it is important that the slip is kept as low as possible. When choosing a profile (surface struc- ture), special attention must be given to the properties the material being mea- sured, such as elasticity, thickness and interaction resistance. Slippage is also influenced by the width of the contac- ting measuring wheel, the pressure of contact, the tensile stress in the mate- rial that is being measured and the angle of wrap. The angle of wrap should be as large as possible.

Wheel bodies are made of cast metal or plastics (see designa- tion). The position of the measuring wheel should be chosen such that the material moves away from the bearing of the sen- sor.
