Slot die gap measurement wand holder
CAPACITEC
During the development of an extremely precise slot die coater gap system, Capacitec discovered the importance of wand positioning when taking gap measurements. The best measurements were attained when the sensor wand was held stable in a parallel position relative to the two halves of the coater die. When the wand was allowed to twist or rock out of this position, accuracy and repeatability would deteriorate. In order to assure best-case parallelism between the sensor wand and the die slot, a special custom fixture was designed. The fixture includes side tabs that can be changed based on gap width and the wand insertion length is easily adjusted.
This fixture offers the following improvements to the measurement process:
* Allows for easy handling and positioning of the wand into coater die slots
* Prevents twisting of wand when positioning wand for measurement
* Prevents wand from rocking out of the ideal measurement area
