Abstract
A simple method is presented for measuring the response of thermocouples in liquid media. Response times down to 50 μsec have been measured. Various coating techniques for obtaining fast responding electrically insulated junctions are discussed. The effect of thermocouple materials and insulation coatings on the response time has been experimentally determined and the results compared with a computer calculation simulating the physical system. The computer calculation involves two difference equations and solves a multilayered media problem without the introduction of heat transfer coefficients. The results agree to within experimental error.This publication has 9 references indexed in Scilit:
