Auto self-calibration arrives for leak testers.A new electronic calibration calibration /cal·i·bra·tion/ (kal?i-bra´shun) determination of the accuracy of an instrument, usually by measurement of its variation from a standard, to ascertain necessary correction factors. system is claimed to be the first to automatically calibrate To adjust or bring into balance. Scanners, CRTs and similar peripherals may require periodic adjustment. Unlike digital devices, the electronic components within these analog devices may change from their original specification. See color calibration and tweak. the leak tester with an adjustable control. The CalVal self-calibration system from InterTech Development Co., Skokie, Ill., is faster, more flexible, and more accurate than mechanical calibration methods. It is supplied as a built-in option for the company's leak testers and reportedly achieves accuracy of [+ or -] 2% of reading or 0.02 sccm. InterTech builds sophisticated leak testers for applications like automotive and medical assemblies. Conventional calibration methods have inherent limitations such as pneumatic pneumatic /pneu·mat·ic/ (noo-mat´ik) 1. pertaining to air. 2. respiratory. pneu·mat·ic adj. 1. Of or relating to air or other gases. 2. valves and other moving parts Moving parts are the components of a device that undergo continuous or frequent motion, most commonly rotation. "Parts" only include the mechanical components which does not include fuel, or any other gas or liquid. that can stick or wear, as well as small gaps or orifices that can clog, notes InterTech. CalVal is an electronic system that requires no operator and no setup time. Tel: (847) 679-3377 * www.intertechdevelopment.com |
