FREEPORT, Ill., February 11, 2005 — Honeywell [NYSE: HON] today introduced two additional offerings in its new family of pressure sensors. Based on Honeywell industry-leading SDX Series sensors, ASDX and ASDX DO Series Pressure Sensors are designed for applications that require precision pressure management. Typical applications include medical equipment, HVAC controls, barometry and pneumatic controls.The ASDX and ASDX DO Series Pressure Sensors are fully calibrated and temperature compensated with on-board Application Specific Integrated Circuitry (ASIC). “The ASDX DO features a digital output, which translates into higher clarity, better response times, and ease of interface with your application,” said Lynn Koch, senior product specialist. “The ASDX DO Series sensors provide digital correction of the sensor offset, sensitivity, temperature coefficients and non-linearity.” The ASDX DO sensors use I2C compatible protocol, which allows easy interfacing to most commonly used microcontrollers and microprocessors without additional components or electronic circuitry. The 2-wire I2C interface has a Serial Clock Line (SCL) input and serial digital output data line. The output of the device is a corrected pressure value in hexadecimal format with 12-bit accuracy. The ASDX Series is amplified with an analog output span of 4.0 Vdc. ASDX and ASDX DO devices are available to measure absolute, differential and gage pressures. The absolute devices 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 gage or differential measurements. The ASDX and ASDX DO Series sensors are available in pressure ranges that cover pressures from 0 psi to 1 psi up to 0 psi to 100 psi. All ASDX and ASDX DO Series devices are accurate to within 2.0 % full scale and are intended for operation from a single 5.0 Vdc supply. The sensors have standard DIP packaging with compact footprints and are designed and manufactured in accordance with standards laid down in ISO 9001 standards. They are intended for use with non-corrosive, non-ionic working fluids, such as air and dry gases. Honeywell ASDX and ASDX DO Pressure Sensors feature highly consistent operating characteristics from one sensor to the next, and interchangeability without calibration. They are a small, low-cost and reliable pressure management solution. For more information, please visit www.honeywell.com/sensing/promo/prasdxdo, or call 800-784-3011 (reference code ASDXDO).
