BP93420DII Differential Pressure Transmitter
The BP93420DII differential pressure transmitter utilizes piezoresistive diffused silicon sensor technology. When differential pressure from the measured medium acts on the corrugated diaphragms at both sensor ends, the Wheatstone bridge output signal maintains excellent linear correlation with differential pressure, ensuring precise measurement performance.
