It also suits position-error checks on cross tables (for example PCB drilling machines) and testing equipment. The scanning unit runs along the scale without mechanical contact. The set consists of a stainless steel U-beam scale carrier with a precision phase-grating scale protected by a glass lamella, the scanning unit, an auxiliary carriage for set-up and the APE 101 interface electronics, which produces two sinusoidal output signals with a 4 µm signal period. Measuring steps as small as 0.02 µm are possible.\u003c\/p\u003e\n\u003cp\u003eIf your unit is giving trouble, Automation and Metrology can evaluate it before you commit to a replacement.
