A non-contact laser for fast, high-performance gauging has been introduced by AMETEK Solartron Metrology. The new Orbit LTH laser triangulation unit delivers 0.02 F.S. (full scale) reading over 2 or 10 mm measurement ranges. This yields accuracy up to .05 µm with the 2 mm stroke. The laser can be networked with as many as 150 different sensors by connecting to Solartron’s Orbit 3 digital measurement system.
Applications include high-volume gauging for quality control of metal and plastic products that could be damaged by contact measurement instruments.
The sensor’s auto-gain circuitry adjusts power based on feedback from the material, providing better readings on difficult surfaces. It can switch between diffuse and specular modes to measure reflective and non-reflective materials. A bridging function can be programmed to account for drop-offs in materials with gaps or holes.
Multiple outputs are available, including USB, Ethernet, TCP, RS232 and Modbus.
