SM5812/SM5852 is an amplified pressure sensor produced by Silicon Microstructures, Inc. It has the characteristics of low cost, fully amplified, calibrated and compensated. It can be used for differential, single-ended differential, gage and absolute applications. The sensor has multiple pressure ranges and can measure pressure from 0.15 PSI full scale to 100 PSI full scale.
The SM5812 and SM5852 series are fully amplified, calibrated pressure sensors in a dual‑in‑line package. They combine a piezoresistive bridge with an on‑chip ASIC that provides multi‑order pressure and temperature correction, delivering ratiometric analog and digital outputs.
These sensors are offered for absolute, gauge, differential and single‑ended applications, with pressure ranges from 0‑0.15 psi up to 0‑100 psi. Typical uses include barometric measurement, medical instrumentation, HVAC, pneumatic control, and gas flow monitoring.
| Zero output (absolute and gauge) | 0.50 V (typical) |
|---|---|
| Current consumption | 10 mA (typical) |
| Response time | 2 ms |
The output is ratiometric to the supply voltage and is available as both analog (4 VFS) and digital (I2C) signals.
Typical applications include barometric measurement, medical instrumentation, pneumatic control, gas flow, respirators and ventilators, and HVAC systems.
