Elmos Introduces First Digital Pressure Sensor with AccuStable Technology

SMI (Silicon Microstructures, Inc.), a subsidiary of Elmos, is proud to introduce the SM3041 fully digital, medium pressure MEMS differential and gauge sensor family. The sensor has better than 1% initial accuracy and less than 1% accuracy shift over life (1% shift over 1000hr HTOL at 150C).

This makes it one of the most stable medium pressure sensors in the market. Furthermore it is the first SMI sensor with the AccuStable marking. Only products combining an extraordinary accuracy with a long-time stability are allowed to have this high quality label.

Highly Stable, Highly Accurate Medium Pressure Sensors

The pressure sensor family is developed with special focus on the following markets: Medical (ventilators, oxygenators, wound therapy, fluid evacuation and others), Industrial (gas flow, pneumatic gages, pressure switches) and Consumer (sport equipment, appliances). The manufacturing line is qualified to the highest industry standards (ISO9001 & ISO/TS 16949).

The SM3041 Series is developed and manufactured with state-of-the-art pressure transducer technology and CMOS mixed signal processing technology. It produces a digital, fully signal conditioned output. The integrated temperature compensation ranges from -20 to +85 C. Standard differential parts are offered at +/-5 and +/-15psi, but the device can be fully customized per customer requirements anywhere in the range of +/-2.5psi to +/-15psi. The SM3041 family has an I2C digital communication interface. The device is offered in several JEDEC SOIC16 package configurations, with dual vertical ports, dual horizontal ports or a single vertical port.

Combining the pressure sensor with a signal-conditioning ASIC in a single package simplifies their use. The pressure sensor can be mounted directly on a standard printed circuit board and a calibrated pressure signal can be acquired from the digital interface. This eliminates the need for additional circuitry, such as a compensation network or microcontroller containing a custom correction algorithm.

The SM3041 is shipped in sticks or tape & reel.

SMI is offering proven solutions to a range of industries, based on application-specific ICs, sensors and complete microsystems. SMI is an ISO/TS16949:2009 certified premier developer and manufacturer of MEMS-based pressure sensors for a broad range of markets, with over 25 years of experience. SMI's design, production and quality control processes have enabled it to develop both the most sensitive and smallest MEMS pressure sensors available on the market today.
