One LaserGauge® system can be used for many different applications because its power and flexibility is in the software. Standard dimensional measurements are made using software algorithms called Virtual Gauges. Complex or unique measurement requirements can be automated through custom-programmed algorithms, called LGBasic Algorithms. All Virtual Gauges and LGBasic Algorithms run on all LaserGauge® systems. Many industries have the same or similar dimensional inspection needs, but use different terms to describe the same type measurement. For example, the Automotive industry uses the term “flush” while Aerospace uses the term “mismatch” to describe the measurement of alignment between two panels. If you do not find the measurement or application you are looking for in the table below, contact us. We will be happy to discuss your measurement requirements. There are three types of LaserGauge® systems: (1) battery-powered, (2) pc-based and (3) controller-based. With all three types, the sensor uses a visible semiconductor laser and imager to capture a scan or profile of the surface being inspected. The difference between the three types of systems is the location of the processor used to analyze the scan. Battery-powered sensors have an on-board processor (DSP), while pc based systems use the power of a computer, and controller based sensors use the processor in a LaserGauge® controller. BATTERY POWERED The on-board processing power allows these sensors to be used without any cables or any connection to an external component. A rechargeable, lithiumion battery provides up to four hours of continuous use. The high resolution imager provides the density of scan points for critical measurements. A graphical display provides real-time profile images and measurement results. Data and scan files are saved automatically to its non-volatile memory. Alternatively, the data can be broadcast to a local computer through a wireless connection. The HS701 sensor is the most versatile of the batterypowered sensors. In the aerospace industry, it is used to measure fastener height and angle, countersink diameter, length and angle, gaps, surface steps, and groove depths. In the automotive industry, it is used to measure gap and flush on body-in-white and on painted vehicles. The HS710 sensor is used to measure smaller features such as pitting or corrosion depth, edge radii, chamfer angle and length, and to inspect laser welds. PC-BASED Connected to a tablet, laptop or desktop, the PC-based sensors are the fastest of all sensors at completing scans and calculating the desired measurements. Power to the sensor is obtained through a USB 2.0 cable connected to a computer and there are no batteries or external connections required. The handheld HS720 sensor utilizes a dual laser-stripe to measure the radius on break edges and to measure other continuous features. The second stripe provides additional orientation information for greater accuracy and repeatability. Sensors used for stationary or tool-mounted applications include the RS750 model. CONTROLLER-BASED These sensors can only be used with a controller. A graphical controller provides real-time scan images and displays measurement results in a data table. Inspection routines can be developed and run on the controllers providing both graphical and text instructions to the operator about the location of the measurement points. Measurement data and scan images are saved automatically on the controller for subsequent transfer to a computer. There are a number of controller- based sensor models, each with their own advantages when used in specific applications. The HS306 sensor has a graphical display for enhanced image presentation, and it offers an optional barcode scanner for automatically identifying the part or assembly being inspected. The HS410 sensor has the greatest resolution of the model group and is used extensively in repair shops for measuring pitting, corrosion, scratches and other foreign object damage.
