Pressure and Temperature Sensor - 89BSD

Applications: Level Controls, Tank Level Measurement, Corrosive Fluids and Gas Measurement Systems, Sealed Systems, Manifold Pressure Measurement, Barometric Pressure Measurement, Dive Computers

Industries: General Industry, Consumer Goods


Datasheet: 89BSD

Description: The 89BSD is a 9mm diameter small profile, media compatible, piezoresistive silicon pressure sensor packaged in a 316L stainless steel housing. This low power 24-bit ΔΣ 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. For a similar sensor with a plastic threaded fitting, refer to the LM pressure transducer.
