This low power 24-bit DS ADC digital output pressure sensor supports an I2C interface protocol and is designed for threaded o-ring mounting. A custom ASIC is used for temperature compensation and offset correction. The sensing package utilizes silicone oil to transfer pressure from the 316L stainless steel diaphragm to the sensing element. A flex cable allows the 89BSD to connect to a smaller connection terminal where size is of primary concern. The 89BSD is designed for high performance, low pressure applications.
