Introduction of flush diaphragm pressure sensor:
The BP93420-III-FL pressure transmitter utilizes the HT series silicon resistive film oil-filled core as the signal measuring element. Its process connection involves the direct welding of a 316L isolation diaphragm and matching flange, ensuring precise pressure measurement. The customized heat sink is designed to adapt to high-temperature environments. Inside the stainless steel housing, the signal processing circuit converts the sensor signal into a standard output signal. Rigorous testing and aging screening of the components, semi-finished products, and finished products have been conducted to guarantee the transmitter's stable and reliable performance.
