Features
SS311 series small pressure sensor combines a piezoresistive pressure transducer with -40 to 105°C capable signal conditioning in one package. The package is compact and easy to integrate. The entire sensor is embedded within a hermetically sealed, oil-filled housing. It is highly resistant to environmental influences. OEM products can seamlessly integrate the sensor. Thus, it achieves cost savings and improves system performance.
SS311 series utilizes high-stability piezoresistive pressure transducers and innovative digital signal processing. Now, we integrate the pressure sensor and signal processor into a miniature, hermetically sealed housing no larger than was once required for the sensor only!
