描述 Description

ASDX Series, digital output I2C address 0x28, amplified, gage, 0 psi to 1 psi, AV pressure port, DIP, 10% to 90% calibration, 5.0 Vdc power supply.The ASDX Series are silicon pressure sensors offering an I2C or SPI digital interface for reading pressure over the specified full scale pressure span and temperature range.The ASDX is fully calibrated and temperature compensated for sensor offset, sensitivity, temperatureeffects and non-linearity using an on-board Application Specific Integrated Circuit (ASIC).Calibrated output values for pressure are updated at approximately 1 kHz. The standard ASDX is calibrated over the temperature range of 0°C to 85°C [32°F to 185°F]. The sensor ischaracterized for operation from a single power supply of either 3.3 Vdc or 5.0 Vdc.These sensors are available to measure absolute, differential and gage pressures. The absoluteversions have an internal vacuum reference and an output value proportional to absolutepressure. Differential versions allow application of pressure to either side of the sensingdiaphragm. Gage versions are referenced to atmospheric pressure and provide an outputproportional to pressure variations from atmosphere.The ASDX Series sensors are intended for use with non-corrosive, non-ionic working fluids such as air and dry gases. They aredesigned and manufactured according to standards in ISO 9001.
