ABSTRACT:
The useful range of the disclosed pressure transducers is extended by isolating the sensing means of the transducer from bending moments produced in the transducer body by the fluid pressure being measured. The isolating means may comprise an isolating ring interposed between the body and the sensor means, disposed behind a diaphragm which is attached to the isolating ring and the body. The isolating ring is connected to the body by means adapted to hold the sensor means in an established relationship with the diaphragm while being of a character to avoid transmitting bending moments, whereby the isolating ring and the sensor means are isolated from bending moments developed in the body due to fluid pressure.
