Delivery time:Delivery time on request
The SOIC pressure sensors in the SM1X91 series are analog/digital OEM sensors with a new silicon sensing element and modern electronic signal conditioning unit. The integrated digital signal processor permits calibration and temperature compensation during production.
The fully calibrated SM1291/SM1391/SM1491 sensors are supplied in a standard SOIC16 package with two vertical pressure connectors for SMD assembly. Pressure-proportional information in I2C format or as an analog 0.5 – 4.5 V voltage signal acts as an output signal. SM1291/SM1391/SM1491 are autonomous sensors which do not require any additional circuitry.
SM1291/SM1391/SM1491 are suitable for reflow soldering and automatic assembly on a PCB.
The sensor is available in a relative SM1291 or differential SM1391 sensor version or as asymmetrical, bidirectional, differential pressure sensor SM1491.
