Pressure sensor duo for down to 1.24kPa

Honeywell ASDXL and ASDXL DO pressure sensors are for applications that require precision pressure management at low-pressure measurements down to 1.24kPa and 2.5kPa.

Honeywell has introduced two pressure sensors.

Based on its SDX sensors, the ASDXL and ASDXL DO pressure sensors are for applications that require precision pressure management at low-pressure measurements down to 1.24kPa and 2.5kPa.

Potential applications include medical equipment, HVAC controls, barometry and pneumatic controls.

The sensors are fully calibrated and temperature compensated with an on-board ASIC.

The ASDXL DO has a digital output and provides digital correction of the sensor offset, sensitivity, temperature coefficients and non-linearity.

It uses an I2C compatible protocol for interfacing to most commonly used microcontrollers and microprocessors without additional components or electronic circuitry.

The two-wire I2C interface has an SCL input and serial digital output data line.

The output of the device is a corrected pressure value in hexadecimal format with 12bit accuracy.

The ASDXL is amplified with an analogue output span of 2.0V or 4.0V DC.

Both devices can measure absolute, differential and gauge pressures.

They have an internal vacuum reference and an output proportional to absolute pressure.

Differential devices allow application of pressure to either side of the sensing diaphragm and can be used for gauge or differential measurements.

Both sensors come in pressure ranges from 1.24kPa and 2.5kPa to 690kPa.

They are accurate to within +/-2.0% full scale and are for operation from a 5.0V DC supply.

The sensors have standard DIP packaging and are made to ISO9001 standards.

They are for use with non-corrosive, non-ionic working fluids, such as air and dry gases.
