FIELD: metallurgy. SUBSTANCE: device has two spring-actuated rods connected to the measuring instrument by one end. The second end of the first rod contacts with linear and forms thermocouple. The second end the second rod contacts with linear and is carried out of material which excepts thermo-e.m.f. in contact point of rod with linear. Besides the second rod is carried out of material whose hardness is higher than material hardness of liner. EFFECT: increased accuracy and reliability of control. 2 cl, 1 dwg
