ADP1108 Differential Pressure Sensor Product Introduction

Product Summary

The response time of the ADP1108 Differential Pressure Sensor has been optimized for medical ventilation applications.

Mounted in a rugged, chemically inert PPS housing the ADP1108 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 Differential Pressure Sensor is supplied with 5.0 V and provides a 0.25~4.0 V output. Although the output of the sensor is analog, the internal linearization and temperature compensation is performed digitally. This results in a superior accuracy, outstanding resolution (up to 0.05 Pa), and lowest temperature dependence.

The differential pressure is measured by a thermal sensing element. In contrast to other thermal differential pressure sensors only a very small amount of air is required. This leads to a reliable operation even under harsh conditions. In comparison to membrane and piezo-resistive based sensors the ADP1108 differential pressure sensors show an extended measurement range, better offset stability and improved reproducibility even at lowest pressure ranges. In addition the ADP1108 is robust against pressure bursts and shows no sensitivity to the mounting orientatio
