Product News for Band Gap
Thermal Pads: Gap Filler or Gap Pads
Stockwell carries a variety of thermal management products, the most popular being Gap Fillers or Gap Pads. Gap fillers are commonly used to improve the efficiency of heat sinks. (read more)
Wind Turbine rotor/stator gap measurement
As a more precise and repeatable method, Gapman "an electronic feeler gage" is used instead of feeler gages to set the gap between the rotor poles and the stator. This gap is particularly critical at the 6 o'clock position due to the gravity effect of the heavy rotor shaft and magnetic assemblies. In a 1.65 kW model 50 to 60 individual pole gaps must measured.

Maintaining 300°C Gap Uniformity on Extruder Dies
Capacitec is introducing the new non-contact capacitive gap measurement GPD sensor wand that measures extruder lips gaps at operation temperatures up to 300°C. It functions the same as standard dual sensor wands except it opens up new possibilities for use in considerably hotter extrusion and coating die processes. Currently there are no electronic gap gauging tools to confirm gap sizes in... (read more)
Thin gap sensors
Engineers have long been searching for reliable and repeatable methods to measure thin gaps between 0.004" (0.11mm) and 0.20" (5mm). Mechanical contact methods such as feeler gauges, shims and calipers had long been the only available method to measure gaps, even in areas where damage could be caused to polished or sensitive surfaces. (read more)
High Temp CVD to Roller Gap Measurement Sensors
Capacitec is supplying high temperature (800°C) capacitive non contact displacement sensors to maintain the gap between a Chemical Vapor Deposition (CVD) head and a metal foil during the production of Flexible Solar Cell Laminates. A roll-to-roll production process is used in the deposition of various active and non active ultra thin layers onto the solar cell. (read more)
