PRESSURE SENSOR DEVICE WITH A PROGRESSIVE STOPPER

A progressive stopper for a pressure sensing element is able to redistribute and reduce the stress of a diaphragm exposed to high pressure via multi-step contacts, such as at least dual contacts, where the diaphragm (designed for detecting pressure within a defined pressure range) is enabled to withstand much higher pressures above of the defined pressure range, such that the progressive stopper prevents catastrophic failure of the diaphragm. The progressive stopper is created to redistribute and reduce stress on the diaphragm significantly and effectively. The progressive stopper does not limit the output of the pressure sensing element such that the pressure sensing element is able to maintain the output voltage above the maximum output voltage of the defined pressure range when the diaphragm is exposed to high pressures with reduced stresses and strains.
