1 Straightness, Angle and Inclination Measurement Straightness, Angle and Inclination Measurement H-1

2 Straightness, Angle and Inclination Measurement Levels with Natural Measuring Base Mechanical instruments with vial or electronic inclinometers with gravity pendulum are based on longtime stabilisation, on reliability and moreover, on a free of charge measuring base, the centre of the earth. Due to the gravitation, liquids (vials) respectively gravity pendulum depend on the natural reference of the centre of the earth. The position of the pendulum facing the housing of the level is measured by using the measuring faces. Based on these perfect conditions, levels and inclination gauges offer a great number of applications with high precision measurements. The horizontal and vertical positions of the measuring faces on the housing allow form errors of the geometrical elements to be measured on the workpiece. For instance, straightness or flatness errors as well as position errors, such as deviations from parallelism or squareness. Depending on the type of level, readings may differ. Typical measurement outputs are: inclination in / m, respectively in / 10 in radians in mrad angle in decimal output, e.g sexagesimal angle in degrees ( ), minutes ( ) and seconds ( ), e.g Calibrating a try square using the ETALON RA squareness measuring instrument Application of two electronic clinometers in differential mode for the capture of the squareness errors on a machine tool (example).
