Measuring Wheels APPLICATION In order to avoid errors when using measuring wheel actuation, it is important that the slip is kept as low as possible. When choosing a profile (surface structure), special attention must be given to the properties the material being measured, such as elasticity, thickness and interaction resistance. Slippage is also influenced by the width of the contacting measuring wheel, the pressure of contact, the tensile stress in the material 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 designation). The position of the measuring wheel should be chosen such that the material moves away from the bearing of the sensor. Use the following measuring wheels for different transmission ratios of counters: Counter transmission ratio 500:1 50:1 5:1 2:1 1:2 1:5 1:20 CORRECT MEASURING WHEEL OR PULSE GENERATOR WRONG MEASURING WHEEL OR PULSE GENERATOR MEASURING WHEEL CIRCUMFERENCE/ TRANSMISSION RATIO Components 2000 measuring wheel circumference 0.2 m (1/5 yd.) 0.2 m (1/5 yd.) 0.2 m (1/5 yd.) 0.5 m (1/2 yd.) 0.2 m (1/5 yd.) 0.5 m (1/2 yd.) 0.2 m (1/5 yd.)
