The HS733LE sensor is used to inspect the leading edge of blades or vanes used in aircraft and power system engines. Designed to scan both sides of the blade simultaneously, the sensor returns a complete profile around the radius of the blade, which allows the accurate measurement of the thickness and the plotting of the blade profile for comparison to its engineering design. The edge radius can also be analyzed.
The sensor connects to a laptop or tablet PC via a USB 2.0 cable. No other hardware or external power source is required.
Measurement Range – The HS733LE is designed to scan smaller blades and to fit into tighter spaces than the HS730LE model. The HS733LE has a 0.150-inch field-of-view (FOV). The table below shows the range of blade sizes that can be measured using the HS733LE sensor. The range is expressed in terms of the maximum blade thickness at a distance back from the leading edge. This distance is called the setback distance.
Resolution – With a 0.150” field-of-view (FOV), the HS733LE has a scanning resolution of 0.0002”, and measurement accuracy to within 0.0005” (12mm) on the blade thickness.
Connectivity – The hand-held sensor is connected to a computer, laptop or tablet pc with a cable to a USB 2.0 port providing 500mA. No other hardware or external power source is required.
Feedback – Scanning is as simple as positioning the sensor on the edge of the blade and pulling the sensor trigger. Raw video and the plotted profile are displayed in real-time on the laptop or computer used with the sensor. Measurements are recorded when the trigger is released. Out-of-spec conditions are flagged with color symbols.
Programs – Separate programs can be developed for different blades, specifying different profile nominals and templates and different setback distances for thickness measurements.
Documentation – Data displayed in the table can be saved. The blade profile can be saved automatically for each scan, as well as an image of the plotted profile with measurement lines as shown in the above plot window.
