Exposed Linear Encoders
Open lineaire encoders zijn ontwikkeld voor toepassingen in machines en installaties waar een hoge nauwkeurigheid verlangd wordt van de meetwaarde. Typische toepassingen zijn:
For very high accuracy
The LIP exposed linear encoders are characterized by very small measuring steps together with very high accuracy and repeatability. They operate according to the interferential scanning principle and feature a DIADUR phase grating as the measuring standard.
For high accuracy
The LIF exposed linear encoders have a measuring standard manufactured in the SUPRADUR process on a glass substrate and operate on the interferential scanning principle. They feature high accuracy and repeatability, are especially easy to mount, and have limit switches and homing tracks. The special version LIF 481 V can be used in high vacuum up to 10–7 bar (see separate Product Information sheet).
For high traversing speeds and large measuring lengths
The LIDA exposed linear encoders are specially designed for high traversing speeds up to 10 m/s, and are particularly easy to mount with various mounting possibilities. Steel scale tapes, glass or glass ceramic are used as carriers for METALLUR graduations, depending on the respective encoder. They also feature a limit switch.
For two-coordinate measurement
On the PP two-coordinate encoder, a planar phase-grating structure manufactured with the DIADUR process serves as the measuring standard, which is scanned interferentially. This makes it possible to measure positions in a plane.
For application in high and ultrahigh vacuum technology
Our standard encoders are suitable for use in a low or medium vacuum. Encoders used for applications in a high or ultrahigh vacuum need to fulfill special requirements. Design and materials used have to be specially adapted for it. For more information, refer to the Technical Information document Linear Encoders for Vacuum Technology.The following exposed linear encoders are specially adapted for use in high and ultrahigh vacuum environments. • High vacuum: LIP 481 V and LIF 481 V
• High vacuum: LIC 4113 V and LIC 4193 V
• Ultrahigh vacuum: LIP 481 U
Open lengtemeetsystemen van HEIDENHAIN worden overal gebruikt waar behoefte is aan een positionering met een extreem hoge nauwkeurigheid of aan een nauwkeurig gedefinieerde beweging. Om ervoor te zorgen dat aan deze hoge nauwkeurigheidseisen gedurende de gehele levenscyclus van het meetsysteem kan worden voldaan, heeft HEIDENHAIN een nieuwe signaalverwerking ASIC ontwikkeld: de HSP 1.0. Deze video laat zien hoe deze ASIC de fluctuaties in de signaalkwaliteit bijna volledig compenseert en de oorspronkelijke signaalkwaliteit herstelt.
