Process for making sensor for detecting fluid flow velocity or flow amount |
摘要 |
A sensor for detecting a fluid flow velocity or flow amount with high precision and high reliability is made by applying a conductor paste comprising platinum powder and an organic vehicle to the outer surface of a fine inorganic insulating tube, followed by drying and firing, thereby forming a platinum film, processing the platinum film into a spiral band form by laser application, inserting a lead wire into the insulating tube, applying a platinum conductor paste to between the spiral platinum band and the lead wire, followed by drying and baking, thereby connecting the spiral platinum band film to the lead wire.
