ASDX Series Pressure Sensors

The ASDX Series is an amplified version of Honeywell’s proven performer and industry leading SDX Series sensor. 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 DIP (Dual In-line Package) sensors are designed for use with non-corrosive, non-ionic working fluids; such as air and dry gases.

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.

All ASDX Series sensors are accurate to within ±2.0% full scale and are designed for operation from a single 5.0 Vdc supply.
