TE Connectivity SM9000 ultra-low digital pressure sensor

There’s an increasing demand for lower pressure-sensing capabilities in industrial and medical markets. From HVAC and gas flow to continuous positive airway pressure (CPAP), ventilation, and patient monitoring applications, the ability to detect small pressure changes is critical. TE Connectivity’s (TE), SM9000 pressure sensor series offers superior performance and long-term stability in a robust, compact package.

The SM9000 series enables ultra-low pressure sensing offering pressure ranges as low as 125 Pa with a 16-bit I2C digital interface. The sensors are available in gage and differential configuration in JEDEC standard SOIC-16 package with dual vertical or horizontal porting options. With the ability to detect even the smallest pressure changes with high levels of accuracy, these sensors provide long-term stability and a total error band of < 1% FS after board mount and system level autozero.
