The differential-output ASDX series of amplified sensors combines MEMS, ASIC and modern packaging technologies.
Meeting the need for taking the risk and high cost out of system-critical sensing and control and addressing an increasing demand for low cost, accurate, high reliability differential sensors with built-in signal conditioning in a space-saving size, Honeywell Sensor Systems (HSS) has released the differential-output ASDX series of amplified sensors based on combining MEMS, ASIC, and modern packaging technology.
This differential output version of the ASDX series is an amplified product that has a +/-2V DC output centred around a 2.5V DC offset.
This version is fully calibrated and temperature compensated using an onboard ASIC.
These sensors are intended for use with noncorrosive, nonionic working fluids, such as air and dry gases.
Typical applications include medical equipment (respirators, oximeters, sleep apnea), flow calibrators, and instrumentation.
The ASDX series - with its signal-conditioned output - will excel anywhere a small, reliable sensor is needed to monitor differential pressure.
All ASDX devices are accurate to within +/-2.0%, with a temperature-compensated range of -10 to +85C.
This +/-2.0% accuracy includes the combined errors from offset and span calibration, linearity, pressure hysteresis and all temperature effects.
The devices are characterised for operation from a single 5V supply.
ASDX sensors are ideal for applications such as medical respiratory and ventilator controls, ventilation and air flow monitors and gas flow instrumentation.
This new product is the next natural evolutionary stage of the popular ASIC-amplified product family.
