Product Details
Pressure Sensor ASDXRRX005PGAA5(ASDX005D44R) For Gas flow
Instrumentation
Product Overview:
The ASDX series is a kind of silicon pressure sensor, which
provides I2C or SPI digital interfaces for reading pressure within
the specified full - scale pressure range and temperature range. It
is fully calibrated, and the temperature compensation is carried
out for sensor offset, sensitivity, temperature effect and non -
linearity by using the on - board Application Specific Integrated
Circuit (ASIC). The calibrated output value of pressure is updated
at about 1 kHz. The standard ASDX is calibrated in the temperature
range of 0 °C to 85 °C (32 °F to 185 °F).
Features:
- It has a ratiometric 12 - bit analog output.
- With precision ASIC conditioning, it has good performance in the
temperature range of 0 °C to 85 °C (32 °F to 185 °F).
- It supports three pressure measurement types: absolute,
differential and gage.
- The pressure range is wide, and this model can measure 0 to 5 psi
(0 to 3.52 m H2O).
- It can work with a single - power supply of 3.3 Vdc or 5.0 Vdc.
- The total error band is within ±2.0% of the full - scale range at
most.
- It complies with RoHS standards.
Pressure Measurement Types:
- Absolute Type: It has an internal vacuum reference, and the output
value is proportional to the absolute pressure.
- Differential Type: Pressure can be applied to either side of the
sensing diaphragm.
- Gage Type: Referenced to atmospheric pressure, it provides an
output proportional to the change of atmospheric pressure.
Application Scenarios:
- Flow calibrators.
- Ventilation and air - flow monitors.
- Gas flow instrumentation.
- Sleep apnea monitoring and therapy equipment.
- Barometry.
- Pneumatic controls.
- HVAC systems.
