THERMOELECTRIC UNIT FOR CHECK OF THICKNESS OF LAYERS OF DOUBLE-LAYER CONDUCTING MATERIALS

摘要

FIELD: measurement technology. ^ SUBSTANCE: proposed device is provided with thermal screen surrounding hot measuring thermal probe which is electrically insulated from it; thermal probe is provided with heater and is made in form of hollow thick-walled metal cylinder manufactured from high-conducting material for forming thermal field with isothermal surfaces; one surface coincides with interface of layers. Located in body of screen are additional heater and auxiliary thermal probe which is also electrically insulated from thermal screen. ^ EFFECT: reduction of measurement error due to thermal protection of measuring channel. ^ 2 dwg
