Specification

Measurement principle: Comparison measurement. Displacement sensor is used to measure the difference between the measured parts and the calibration parts, and then the relative sizes of the measured parts are calculated. The whole control system adopts Profinet bus communication mode for OPC communication with the host computer. The integration is strong and the communication is safe and reliable.

Measurement range: Manual adjustments for various sizes measurements. Centre-to-centre distance: 120mm-150mm, large bore inner diameter: 40mm-60mm, small bore inner diameter: 15mm - 30mm, big end thickness: 18mm-30mm.

Measurement takt time: ≤10 seconds, under normal condition and operation

Measurement position technology level: sensor resolution: 0.0001mm, measurement accuracy: ±0.001mm, GRR: ≤10%.
