Abstract
A pressure sensor includes a sensing element in a sensing chamber defined by two cases, one of which is crimped to the other. An internal pressure of the chamber is affected by a crimping force. In the manufacturing process of the pressure sensor, the internal pressure is monitored during crimping the cases. To monitor the internal pressure, the sensing element of the pressure sensor is used. An output signal of the sensing element is sent to a crimping machine. The crimping machine controls a crimping force based on the output signal.
