www.honeywell.com/sensing 1 The pressure is on. The answer is here. No matter the need, Honeywell Sensing and Control (S&C) has the microstructure, pressure sensor solution. Our sensing element design consists of four piezoresistors galvanized with a thin, chemically etched silicon diaphragm. A pressure change will flex the mechanism, causing a strain in the diaphragm and the buried resistors. The resistor values will change in proportion to the stress FEATURES Ultra -Low Presure Sensors ASDX Series. Features: Calibrated and temperature compensated • ASIC-enhanced output • Analog output with 12-bit resolution • 12-bit digital output (I2C- or SPIcompatible protocol) • Ratiometric output • Enhanced response time and accuracy • DIP package • Cost effective Benefits: Fully calibrated and temperature compensated with on-board ASIC designed to provide digital correction of sensor offset, sensitivity, temperature coefficients, and non-linearity. Analog output ratiometric with supply voltage over compensated supply range with 12-bit resolution. 12-bit I2C- or SPI-compatible protocol allows easy interfacing to most commonly used microcontrollers and microprocessors without additional components and electronic circuitry. Output is corrected pressure value in hexadecimal format with 12-bit accuracy (unsigned) and independent of the supply voltage. Offers high level output on a costeffective basis. Intended for use with noncorrosive, non-ionic working fluids such as air and dry gases in potential applications Silicon Pressure Sensors Line Guide continued on page 10 such as flow calibrators, ventilation and airflow monitors, gas flow instrumentation, sleep apnea monitoring, and therapy equipment. CPCL Series. Features: Calibrated and temperature compensated • Cost effective • Small size • Constant voltage excitation • High impedance, low current Benefits: Integrates silicon micromachined sensing technology, temperature compensation, and calibration in a small, cost-effective package. Tube arrangements with nylon housings available for various pressure applications, especially those requiring small size or vacuum reference. Although designed for use with non-corrosive, non-ionic pressure media, sensors may accommodate many potential medical application gases. CPXL Series. Features: Non-calibrated and nontemperature compensated • Small size • Cost effective • Constant voltage excitation • High impedance, low current Benefits: Integrates silicon micromachined sensing technology in a cost-effective package. Tube arrangements with nylon housings available for various pressure applications, especially those requiring small size, or vacuum reference. Although designed for use with non-corrosive, non-ionic pressure media, accommodates many potential medical application gases. DCXL-DS Series. Features: Calibrated and temperature compensated • Improved stress isolation • Reduced output offset errors Benefits: Based on proprietary technology designed to reduce output offset or common mode errors due to changes in temperature, warm-up, long-term stability and position sensitivity. Features calibrated offset, full scale span and thermal error calibration to promote accuracy for flow pressure measurement. Industry-standard, ported package with improved stress isolation for printed circuit board mount applications. Used in medical, HVAC and industrial instrumentation applications. applied, which produces an electrical output. So you’ll find our components performing in potential applications including dialysis equipment, blood analysis, centrofusion and oxygen and nitrogen gas distribution, HVAC devices, data storage, process controls, industrial machinery, pumps, and robotics. Honeywell S&C is always working harder, no matter the situation. Or the pressure.
