Copyright Albion Devices, Inc., An Introduction to TComp n Albion Devices, Inc., is pleased to present the following slide presentation that introduces the functions of our TComp (“tee- comp”) snap gages and Digital Indicators. The unique, built-in temperature compensation capabilities of these units make them the most consistently accurate shop floor snap gages and indicators available. Albion Devices, Inc 742 Genevieve St. Solana Beach, CA This is a MS Powerpoint presentation. Please use mouse clicks, space bar or arrow keys to move between slides.

Copyright Albion Devices, Inc., TComp is unlike any other indicator. n TComp is a battery or mains powered indicator that is designed to fit on a custom snap gage frame or other gage fixture so as to take temperature compensated comparative measurements.

Copyright Albion Devices, Inc., n Mounted on a manually operated snap gage, TComp can produce accurate and repeatable measurements to within + / inch (5 microns) or better, over a temperature range of 40ºF to 140ºF (5ºC to 60ºC). Snap Gage configuration

Copyright Albion Devices, Inc., Fixture mounted applications n Mounted in a fixture or a stand, TComp is capable of accurate and repeatable measurements to within + / inch (2.5 microns) or better, over a temperature range of 40ºF to 140ºF (5ºC to 60ºC) on the shop floor. n Tcomp can also be mounted on a bar gage for critical large diameters.

Copyright Albion Devices, Inc., Tcomp’s transducers n TComp indicator is equipped with a transducer assembly that contains 3 sensors: an LVDT, a workpiece/master temperature sensor (that senses through the carbide face of the measuring anvil) and a gage fixture temperature sensor (that monitors the temperature of the frame or fixture in which it is mounted). Workpiece sensor LVDT Gage senso r

Copyright Albion Devices, Inc., Controls n TComp is programmed and operated through a simple touch pad on the front panel. n An LCD displays data and measurements.

Copyright Albion Devices, Inc., Transducers n LVDT probe and temperature sensors are mounted within the gage fixture so as to make suitable contact with respective components. n The “Gage” sensor monitors the temperature of the snap gage frame. The “Workpiece” sensor senses the temperature of the workpiece and the master.

Copyright Albion Devices, Inc., Operation n In operation, TComp notes the temperature of the master during the mastering (zeroing) cycle, then switches automatically into Measure Mode. In this mode it assumes that it is measuring a workpiece and applies the respective correction coefficient. Meanwhile, the gage sensor applies yet another coefficient to any changes in gage fixture or frame temperature.

Copyright Albion Devices, Inc., Compensation Algorithm n TComp’s programmed algorithm takes into account any variation in the temperatures of the workpiece, master or gage fixture from Nominal Temperature (usually 68°F/20°C). Workpiece Temperature Master Temperature Gage Temperature Workpiece Coefficient Master Coefficient Gage Coefficient Compensation Algorithm Temperature Corrected Dimension

Copyright Albion Devices, Inc., Algorithm (cont) n TComp applies these variations to user- programmable correction coefficients (expansion coefficients) and to the user programmable nominal dimension (since coefficients are expressed in terms of size variation (inch or MM) per degree of temperature (°F or °C) per unit of dimension (inch or MM)).

Copyright Albion Devices, Inc., Correction to 68°F/20°C n The net size variation after allowing for expansion or contraction in all 3 elements is applied in real time to dimensional measurements made by TComp’s LVDT. n The result is that all displayed dimensions show the size that the workpiece would measure if it, the master and the gage frame were all at Nominal Temperature (68°F/20°C).

Copyright Albion Devices, Inc., Stack gage n Dual TComps can be mounted into a specially designed bearing cup gage, called a “stack gage”. These are used extensively in the railroad industry.

Copyright Albion Devices, Inc., Temperature sensing n The key to the success of TComp’s system is in accurate and rapid temperature sensing. n This is accomplished by using stable and accurate electronic chip and thermistor technology housed in protective housings within the gage.

Copyright Albion Devices, Inc., The Dramatic Potential n Temperature Compensation of precision gages provides dramatic improvement in: n Process control n Gage repeatability n Gage correlation n Scrap and rework reduction n Overall quality control

Copyright Albion Devices, Inc., Product Range n The remarkable thermal correction capabilities of TComp can be applied to many gaging situations. Be sure to ask us about our wide range of temperature compensated gages and systems.
