The SM923X Series are digital, ultra low gauge pressure sensors for extremely low air pressures. 3 calibration ranges are available:
- SM9233: 0 to +250 Pa (0-1" H2O)
- SM9235: 0 to +300 Pa
- SM9236: 0 to + 600 Pa
In addition, users have a choice of accuracies when ordering - either 3%FS, 2.5% FS or 1.5% FS after autozero. The sensors have a 16-bit I2C digital pressure calibrated and temperature-compensated output. The SM923X Series have a standard SOIC-16 package with a dual vertical port.
