APPARATUS FOR MANUFACTURING THERMOCOUPLE UNITS

摘要

This invention relates to a mould for use in manufacturing thermocouple units of the type having a bi-metal junction located in a glass u-tube to project from a body of ceramic material, comprising a mould for a thermocouple unit formed in at least two mould members of mouldable material. These members include means for locating and holding at least some of the non-ceramic components of the thermocouple unit, in accurate spaced relation to each other prior to introduction of the ceramic material.
