Title:
PRESSURE SENSOR HAVING JOINT MEANS
Document Type and Number:
Japanese Patent JP2004333139
Kind Code:
A
Abstract:
To provide structure for a pressure sensor in which a pressure introducing pipe can be securely connected to a joint pipe.
A junction surface 13 of the pressure introducing pipe 11 and a junction surface 31 of the joint means 3 are laser-welded in this pressure sensor. At a lower end part of the pressure introducing pipe 11, an inclined surface 14 is provided. Outer diameter d13 of the junction surface 13 of the pressure introducing pipe 11 is set to be equal to outer diameter d31 of the junction surface 31 of the joint means 3. Inner diameter d12 of the junction surface 13 and inner diameter d32 of the junction surface 31 are set in different size from each other.
