Abstract

Abstract:

An integral system is presented based on a microcomputer data acquisition, which can be used in on line checking of the time constant of thermocouples and measuring of dynamic temperature.Time constant of thermocouple is checked on line with an electric heating method, and with the same thermocouple temperature is measured.

Key words: thermocouple, dynamic temperature, measurement, on-line checking, timeconst ant, dynamic compensation
