Thermocouple and resistor for oil & chemical industry
Cut-off wear-resistant thermocouple
Cut-off wear-resistant thermocouple
产品概述

Cut off the wear-resistant thermocouple is the special thermocouple for the process of refining, and its measurement terminal use temperature resistance , wear-resistant, corrosion-resistant materials, except the wear-resistant, corrosion-resistant characteristics, When the protective tube use wear, leakage occurs It can artificially close the shut-off valve to prevent the continued occurrence of leakage. So cut off wear-resistant thermocouple is one of the essential products to ensure the safety of oil refining production

It is built-in single or double armored components, process connection flange, thread and other forms. Thermocouple K, E, J and other optional.
