差圧検出装置
Document Type and Number:
Japanese Patent JP6983744
Kind Code:
B2
Abstract:
A differential pressure measurement range is widened and differential pressure can be measured particularly during low differential pressure. A first spool facing a space in a high pressure side is lighter than a second spool facing a space in a low pressure side in a state where a magnet is provided. Urging force of a first elastic member that urges the first spool toward the space in the high pressure side is smaller than urging force of a second elastic member that urges the second spool toward the space in the high pressure side, and the first elastic member and the second elastic member are disposed in series.
