154BSD Digital Output Pressure Sensor
Brand: American Sensor Technologies IncThe 154BSD is a small profile, media compatible, piezoresistive silicon pressure sensor packaged in a 316L stainless steel housing.
This 14-bit digital output pressure sensor supports I2C and SPI interface protocols with a 3.3 or 5.0 Vdc supply voltage and is designed for o-ring mounting.
The sensing package utilizes silicone oil to transfer pressure from the 316L stainless steel diaphragm to the sensing element.
The 154BSD is designed for high performance, low pressure applications. A custom ASIC is used for temperature compensation, offset correction, and provides a digital output of 10% to 90% or 5% to 95%.
