ABSTRACT:
A transmitter measures pressures and has a pressure sensor and an additional pressure sensor providing additional measurement capability to the transmitter, such as an extended measurement range or measurement redundancy. Both pressure sensors share an overpressure protection device which protects them from pressures exceeding a preselected pressure limit. The pressure sensors are batch fabricated and are formed in a single piece of brittle material.
