ABSTRACT:
A transducer of an H-shaped cross section employs a depression relatively equal to the line width of a diffused piezoresistor located in said depression. The depression is sealed by means of a glass member which acts as a "stop" for the transducer for all forces in excess of a rated force which causes a maximum diaphragm deflection relatively equal to the depth of said depression as selected in accordance with said resistor line width and the overall diaphragm diameter.
