Gapmaster® 3 - Three Position Sensing
The Gapmaster® 3 is lightweight and fully portable. The Gapmaster® 3 features three pre-amplifiers providing users with up to three channels for non-contact displacement sensors measurement system. Sensors can be selected among displacement sensors (HPB, HPC, HPT) or single point gap sensors (HPS, GPS).
The Gapmaster® 3 features:
- A three-line display indicating the currently measured distances in engineering units (mils, inches, microns, millimeters).
- Fully portable package powered by 3 AA lithium batteries with a minimum battery life of 22 hours
- Bright blue alphanumeric Active-Matrix OLED display
- External unit selector button for mils, inches, microns, or millimeters
- Inclusion of an industry standard USB Type A combination data output and external power port
Gapmaster® 3 for Aircraft Component Joining
When two large Aircraft structural elements are joined together and overlapping sections have ideally no gaps, but in practice there are air gaps. These must be filled with liquid shims or structural shims before the fasteners are applied. These overlapping sections can create a wedge like or tapered air gap. A 3-point gap measurement tool with sensors located from inbound to middle to outboard can predict this complex shim shape to fill this void. An example of a 3-point contact wand (Model 3HPB7-7) matched to a Gapmaster® 3 simultaneously records these 3 gaps and sends them to a CNC machine to create a custom shim for this exact location.
Other precision measurement applications include:
- Semiconductor wafer parallelism
- 2- or 3-point slot die coater to media parallelism
- 2- or 3-point roller parallelism
- 2- or 3-point engine fan blade gap
- Universal 1, 2 or 3-point dimensional measurement
