ADP1108 Differential pressure sensor

Description

1.  Product Summary;

The response time of the ADP1108-R is optimizing for medical ventilation applications.

Mounted in a rugged, chemically inert PPS housing the ADP1108-R differential pressure sensors feature a unique dynamic range, zero offset and unsurpassed long term stability. This makes it an ideal fit for demanding yet cost sensitive OEM applications in medical and HVAC equipment.

The ADP1108-R is supplied with 5.0 V and provides a 0.25~4.0 V output. Although the sensor has an analog output, the internal linearization and temperature compensation are executed digitally. This results in a superior accuracy, outstanding resolution (up to 0.05 Pa), and lowest temperature dependence.
Its leading performance is based on ASAIR proprietary ASAIR® sensor technology. A thermal sensing element measures the differential pressure. Compared with other thermal differential pressure sensors, it only requires a very small amount of air. This leads to a reliable operation even under harsh conditions. In comparison to membrane and piezo-resistive based sensors the ADP1108-R differential pressure sensors show an extended measurement range, better offset stability and improved reproducibility even at lowest pressure ranges. In addition, ADP1108-R has strong resistance to pressure explosion and is not sensitive to the installation direction.
