Title:
PRESSURE SENSOR
Document Type and Number:
Japanese Patent JP2010249524
Kind Code:
A
Abstract:
To provide a pressure sensor including first and second sensor parts 20, 30 on which gauge resistors 25a-25d, 35a-35d are respectively formed, and providing improved detection accuracy of pressure than a conventional pressure sensor.
The first and second sensor parts 20, 30, having identical shape and being of a square-plate type include first and second drop regions 12a, 13a, where a seal member 50 drops onto first and second recessed parts 12, 13 having the identical shape, respectively. The arrangement of the gauge resistors 25a-25d in the first sensor part 20, in relation to the first drop region 12a and the arrangement of the gauge resistors 35a-35d in the second sensor part 30 in relation to the second drop region 13a, are identical.
