Heat transmission measuring unit with measurement head acted on by fluid to be measured

摘要

The has a measurement head (10), acted on by a fluid to be measured. It has a calorimetric sensor (18) standing in contact with a heat-conducting partition wall (16). The partition wall is designed as a prefabricated thin-walled disc with a selected wall thickness. This is material keyed connected with an opening edge (20) of a tubular attachment (14) at the measuring head (10). The thin-walled disc (16) is welded or soldered to the tubular attachment. The disc is made of metal and can be connected to the tubular attachment using a laser welded seam. The prefabricated disc is equipped with the sensor (18).
