Patent ID: 6883219

Claim:
A method for manufacturing a sensor device having a sensing chamber defined by a first case and a second case, one of which is crimped to the other, and a sensing portion in the sensing chamber, wherein an internal pressure of the sensing chamber is affected by a crimping force applied to the case crimped to the other, comprising: arranging the sensing portion in a well formed in the first case; introducing a pressure transmission medium in the well; fitting the first case and the second case together; applying the crimping force to one of the first and the second cases for crimping the one of the first and the second cases to the other of the first and the second cases; monitor the internal pressure of the sensing chamber by monitoring an output signal of the sensing portion during the application of the crimping force; and controlling the crimping force based on the monitored output signal to adjust the internal pressure of the sensing chamber to a predetermined level.
