TE Connectivity / Measurement Specialties 89BSD Digital Output Pressure Sensors

TE Connectivity's Measurement Specialties 89BSD Digital Output Pressure Sensors feature a small profile with a 9mm diameter and 316L stainless steel housing. These piezoresistive silicon pressure sensors are media compatible and support an I²C interface protocol. A custom ASIC is used for offset correction and temperature compensation. The sensing package utilizes silicone oil to transfer pressure from the 316L stainless steel diaphragm to the sensing element. These low-power, 24-bit ADC digital output pressure sensors are designed for threaded O-ring mounting. A flex cable allows the 89BSD to connect to a smaller connection terminal where size is a concern. TE Measurement Specialties 89BSD sensors are created for high performance, low pressure applications such as level controls, sealed systems, dive computers, and tank level measurement.
