MULTIFUNCTIONAL DIFFERENTIAL THERMAL CONDUCTIVITY METER USED TO MEASURE THERMAL CONDUCTIVITY OF COMPOSITES AND CLOTHES

摘要

Višenamjenski diferencijalni konduktometar načinjen je od mjernog valjka (1) s grijačima (2) i senzorom temperature (3) toplinski izoliranog teflonom (4) unutar prvog čuvara topline (5) zagrijavanog grijačima (6) i s temperaturnim senzorom (7) te drugim čuvarom topline (8) debljih mjernih uzoraka (9) postavljenih na mjernu bazu (10) da nasjedaju na nju i teflonski prsten (11). Čuvari topline imaju mjerno regulacijske sustave (12) i (13), a mjerni valjak mjerno regulacijski sustav (14) za mjerenja snage održavanja stacionarnog stanja. Senzorima (15) između slojeva mjere se diferencijalne temperature sklopom (16), mjerne baze sklopom (17), a pomoću sklopa (18) temperatura mjerne baze i unose u računalo (19) za izračun toplinskih svojstva uzoraka u opuštenom ili komprimiranom stanju postignutom nosačem (20), dinamometrom (21), konzolom (22) i pomičnim mehanizmom (23) s vodilicama (24) do kontakta mjernog valjka s uzorkom utvrđenog videokamerom (25) i monitorom (27) ili pritisnom silom dinamometra uz podatke mjerila pomaka (27).Multifunctional differential thermal conductivity meter is made of a measuring roller (1) with heaters (2) and a temperature sensor (3) thermally insulated with Teflon (4) within first heat protector (5) heated with the heaters (6) and with a temperature sensor (7) and another heat protector (8) of thicker measuring samples (9) set onto the measuring base (10) to sit on it and a Teflon ring (11). Heat protectors have measuring regulation systems (12) and (13), and a measuring roller has a measuring regulation system (14) to measure power of maintaining stationary condition. Sensors (15) between layers are used to measure differential temperatures with a set (16), measuring bases with a set (17), and with the aid of a set (18) to measure temperature of a measuring base and to be entered in a computer (19) for calculation of thermal features of samples in loose or compressed condition achieved by a support (20), a dynamometer (21), a console (22) and a movable mechanism (23) with guides (24) up to the contact of the measuring roller with a sample identified with a video camera (25) and a monitor (27) or compression force of a dynamometer with shift gauge data (27).
