Since 1845, Gurley has been a major designer and producer of measuring instrumentation for a variety of industries and applications. Our areas of expertise include optical encoders for the precise measurement of position or speed; digital readout systems for retrofitting machine tools; generation and replication of precise patterns on glass and 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 received ISO-9001 certification in January, 1996.
We offer Optical Encoders for both rotary and linear motion, in conventional incremental and 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 and printing equipment, machine tools, radar pedestals, and high speed scanners.
Our self-contained rotary incremental encoders are available in a variety of sizes, from 0.75" dia with up to 40,960 counts/rev, to a 6" dia model with 3,600,000 counts/rev. An industrial-grade rotary absolute encoder offer resolution up to 217 words/rev. Modular rotary incremental encoders provide a wide choice of size and resolution, while linear encoders come in many mounting configurations, lengths, and accuracy grades. Virtual Absolute encoders are available as rotary or linear encoders in both self-contained (housed) and modular configurations.
Gurley specializes 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.
Our Optics and Optographics product line comprises the generation and replication of precision optical patterns and parts such as reticles, resolution targets, encoder discs and scales, prisms, mirrors, beam splitters, filters, lenses and step wedges. The patterns are most commonly vacuum deposited chrome on glass; however, we also work with other pattern materials such as silver, inconel, aluminum, and photographic emulsion. Other substrates include plastic, fused silica (quartz), sapphire, mylar film, zinc selenide, silicon, germanium, and zinc sulfide.
We have some catalog items, but over 90% of our sales are items fabricated to meet customer's drawings and specifications. The products are used in fire-control systems, optical encoders, guidance systems, and other types of optical, electro-optical, and laser based systems operating in either the visible, infrared, or ultraviolet portion of the spectrum.
Hydrological Instruments are used to measure flow velocity in open channels such as rivers, streams, tidal marshes, sewers, flumes, conduits, etc. The product line comprises two models of bucket-wheel flow meters that cover the velocity range of 0.015 to 7 m/s. There are two readouts available: an earphone assembly that is used to count clicks over a fixed period of time, and a completely automatic hand held digital display.
Genuine GurleyTM Film, Sheet, and Paper Testing Instruments have been the industry standards for decades for measuring physical characteristics such as stiffness, flexibility, softness, porosity, air-permeability, and smoothness. Gurley instruments are used extensively in the paper manufacturing, paper board converting, printing, medical product manufacturing, and textile/non-woven industries. While used most often to test thin flat materials, small dimensional parts such a tubing can also be tested.
To meet the needs of measuring those characteristics over a wide range of parameters, we offer three models of stiffness testers, seven densometers, and a permeometer.
