Introduction of flush diaphragm pressure sensor:
The BP93420-III-FL pressure transmitter uses the HT series silicon resistive film oil-filled core as the signal measuring element. The process connection adopts direct welding of 316L isolation diaphragm and matching flange to ensure the precision of pressure measurement. The customized heat sink can adapt to high-temperature environments. The signal processing circuit located inside the stainless steel housing converts the sensor signal into a standard output signal. The entire product has undergone rigorous testing and aging screening of components, semi-finished products, and finished products, ensuring stable and reliable performance.
