SMI (Silicon Microstructures, Inc.), a subsidiary of Elmos, today announced the introduction of the SM5211 and SM6221 fully digital, low-pressure MEMS sensors 
series. The series covers pressures from 0.8 to 2.0 psi (56 to 140 cm H2O) with an initial accuracy of better than 1% and a total output offset of less than 1% (1000 hours of HTOL, 1% offset). AccuStableTM features ensure they are the most stable low pressure sensor . The SM1221 and SM4221 products with this feature were released earlier this year. Only products that combine superior precision with long-term stability have such high quality. The fifth series, the SM7221, is currently being released with a pressure range that extends down to 0.15 psi.
Pressure sensor The series was developed specifically for medical (ventilators, oxygenators, fluid discharges, etc.), industrial (airflow, barometers, pressure switches) and automotive (fuel vapor) markets. The product is manufactured to the highest industrial standards (ISO 9001 and ISO/TS 16949).
SMI digital output sensor The series is developed and manufactured using the industry's most advanced pressure temperature compensation range of -20 ° C to +85 ° C. The compensated pressure can be customized from 0.15 psi to 30 psi according to user requirements. The digital interface implements the I2C protocol with vertical and horizontal port options.
Pressure sensor And digital conditioning dedicated chip ASIC microcontrollers.
These products are packaged in a JEDEC standard SOIC-16 package, in a tubular or tape reel package.
SMI is a subsidiary of the global elmos semiconductor group for specific application ICs, sensors And the industrial field of complete microsystems provides proven solutions. SMI is the main developer of ISO/TS16949:2009 certification and is a MEMS pressure sensor for a wide range of markets. The manufacturer has over 25 years of experience. SMI's design, production and quality control processes enable the development of the most sensitive and smallest MEMS pressure sensor on the market today. .
