New Digital SPI Bus Pressure Sensors Offer Precision Measurements



Sensortechnics’ new digital RCE series offers precision absolute, gage or differential pressure measurement from ±10 mbar to 5 bar. These devices generate a calibrated and temperature compensated digital output signal with high resolution and very fast response times. The sensors comply with the SPI bus protocol and can be easily interfaced to microcontrollers without the need for additional electronic components. Custom specific outputs, I2C bus, analog or switching outputs can also be provided on request.


The RCE series utilises the latest ASIC technologies for high precision digital signal conditioning and achieve high total accuracies of up to ±1.0 %FSS (Full Scale Span). The sensors feature highly stable micromachined silicon elements packaged with two pressure ports for easy manifold or tubing connection and mounting holes for convenient PCB-assembly.


Important features of the new RCE series are:

  • Absolute, gage or differential pressure ranges from ±10 mbar to 5 bar Digital output signal using SPI bus protocol

  • I2C bus, analog, switching outputs or custom specific outputs on request

  • High total accuracies of up to ±1.0 %FSS

The digital RCE series offers OEM customers precision pressure measurement for a wide range of applications. Typical examples include medical instrumentation, barometry, HVAC and pneumatic controls.
