The Honeywell ASDX Series Pressure Sensors are an amplified version of Honeywell's proven performer and industry leading SDX Series sensors. The ASDX sensor's footprint is slightly larger than the SDX; however, it offers a high level output (4.0 Vdc span) on a very cost-effective basis. This series is fully calibrated and temperature compensated with on-board Application Specific Integrated Circuitry (ASIC).
These Honeywell DIP (Dual In-line Package) sensors are designed for use with non-corrosive, non-ionic working fluids; such as air and dry gases.
The ASDX sensors are available to measure absolute, differential and gauge pressures. The absolute sensors have an internal vacuum reference and an output voltage proportional to absolute pressure. The differential sensors allow application of pressure to either side of the sensing diaphragm and may used for differential or gage measurements. Bidirectional versions are also available.
The ASDX-DO Series with compensated 14-bit digital output provides either an I2C or SPI digital interface for reading pressure over the specified full scale pressure span and temperature range, minimizing connections and providing higher resolution and faster performance through reduced conversion requirements and the convenience of direct interface to the microprocessors or microcontrollers.
All Honeywell ASDX Series pressure sensors are accurate to within ±2.0% full scale and are designed for operation from a single 5.0 Vdc supply.
