Profile: Gurley Precision Instruments is a designer and producer of measuring instrumentation for a variety of industries & applications. We are an ISO 9001 certified company. Our areas of expertise include optical encoders for the precise measurement of position or speed, digital readout systems for retrofitting machine tools, generation & replication of precise patterns on glass & similar substrates, physical properties test instruments for medical tubing, paper, films, textiles, and other sheet goods, mechanical components, and open-channel flow meters to measure water velocity. We offer optical encoders for both rotary and linear motion in conventional incremental & absolute configurations, and in GPI's unique Virtual Absolute™ technology. They are used to measure or control position and/or speed in medical instrumentation, electronic manufacturing equipment, robotics, factory automation, graphic arts & printing equipment, machine tools, radar pedestals & high speed scanners. We specialize in providing customized solutions to specific problems, whether the answer is a low-cost encoder for high production volumes, or a very high performance encoder for military or aerospace applications. Digital readout systems (DRO's) are an add on accessory for machine tools to provide the machinist with information regarding the position of the cutting tool on the work piece. A system consists of linear encoders which are attached to the machine tool, and a digital display unit which is connected to the linear encoders. Systems are easily added to milling machines, lathes, horizontal and vertical boring mills, grinders, jig borers, or any other type of machine tool. We offer glass-scale encoders for lengths up to 7 ft, and rack-and-pinion encoders for virtually any length on large machines. We provide resolutions as fine as 1µm (50µin). The PointFinder DRO offers all the popular features of CRT-based systems with the visibility, reliability, and price of a standard LED display.
