PRODUCTS: HS742

The HS742 with Blue Laser Technology is a 3D Cross-Hatch sensor and is specifically used for measuring countersink alignment, fastener depth and dielectric fill height in the aerospace industry.

The HS742 DSP sensor with Blue Laser Technology is a 3D laser profiler housed in a totally self-contained, portable, handheld package. Expanding on the unique capabilities of the LaserGauge® line of DSP sensors, the HS742 utilizes a laser stripe grid with cutting edge optics and is specifically designed for inspecting and measuring fastener flushness, countersink alignment and dielectric fill height. Surface maps are displayed in real-time on the color LCD, and measurements are extracted and simultaneously written to the data table.

VIRTUAL GAUGES

Virtual Gauges that come with the HS742

"Virtual Gauges" are the mathematical algorithms used to process a scan and extract measurements from it. The following Standard Virtual Gauges are provided as a part of the preloaded configuration for both the HS702 and HS703 and are used mostly for Gap/Flush and Sheet Metal applications in the automotive industry.

  • Countersink
  • Fasteners
  • Dielectric Fill

Custom Virtual Gauges can be developed/created according to customer requirements and measurement methodology upon request. Learn more about Standard and Custom Virtual Gauges.


Measurement output includes numerical and graphical displays as well as auditory feedback

Display Output

Numerical and graphical results are displayed and can indicate in- or out-of-spec conditions. Operation feedback is provided to assist the operator in obtaining the best measurements.

Auditory Output

A variable volume speaker will sound different tones to indicate in- or out-of-spec measurements, errors or misreads, and low battery.

Data Output

All processed scans and the extracted measurements are automatically saved to the sensor memory for later retrieval. When the sensor is plugged into a PC it will map the data memory as a drive, much like a USB memory stick so that retrieving files is fast and easy.
