- 1) The surface of a measuring wheel is subject to wear. This depends on contact pressure, acceleration behavior in the application, traversing speed, measurement surface, mechanical alignment of the measuring wheel, temperature, and ambient conditions. We recommend you regularly check the condition of the measuring wheel and replace as required.2) Based on an encoder with a plug connector output and urethane rollers, no mounting necessary (arm mount).3) Only applies to variants with spring arm mounting.
