SM5221 / SM5321 / SM5421
The SOIC pressure sensors in the SM5X21 series are 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 SM5221, SM5321 and SM5421 sensors are supplied in a standard SOIC16 package with two vertical or horizontal pressure connectors for SMD assembly. Pressure-proportional information in I2C format acts as an output signal. SM5221/SM5321/SM5421 are autonomous sensors which do not require any additional circuitry.
SM5221/SM5321/SM5421 are suitable for reflow soldering and automatic assembly on a PCB.
The sensor is available in a relative SM5221 or differential SM5321 sensor version or as asymmetrical, bidirectional, differential pressure sensor SM5421.
Variants of SM5221/SM5321/SM5421
SM5221 relative pressure ranges: 0 – 0.8 / 2.49 psi
SM5321 differential pressure ranges:
P1: -2.49 – 0.8 psi and P2: 0.8 – 2.49 psi (the absolute values of P1 and P2 must be identical. Please see the datasheet.)
SM5421 asymmetrical bidirectional pressure ranges:
P1: -2.49 – 0.8 and P2: -0,8 – 2.49 psi (the absolute values of P1 and P2 may differ from one another. The difference between P1 and P2 must be greater than 0.8 psi, however. Please see the datasheet.)
