SENSORS:Honeywell has continued its expansion of the industry-leading ASDX silicon pressure sensor family with the new ASDX Series which now offers pressure ranges of 15, 30 and 100 psi. With this launch, Honeywell’s ASDX Series portfolio consists of 1 to 100 psi low pressure products and ultra-low pressure products of 0 to 10 inches of H2O gage, ±10 inches of H2O differential, and ±5 inches of H2O differential.
The ASDX Series’ Application Specific Integrated Circuit (ASIC)-based design provides a quick, highly accurate, amplified condition pressure reading. Calibrated output values for pressure are updated at approximately 1 kHz. These sensors offer enhanced application flexibility with output options of ratiometric 12-bit analog or 12-bit I2C or SPI digital; supply voltages of 3.3 or 5.0V dc; standard calibrations including inches H2O, cm H2 O, psi, mbar, bar, kPa; and absolute, differential, and gage pressure types.
Additional signal conditioning incorporated into ASDX Series sensors allows customers to remove components from their PC board in order to free space and reduce costs normally associated with those components (acquisition, inventory, assembly, etc.). Incorporating this ability within the sensor eliminates many potential problems that could arise from having multiple components for signal conditioning spread across a circuit board.
Designed to provide digital correction of sensor offset, sensitivity, temperature coefficients and non-linearity, ASDX sensors are intended for use with non-corrosive, non-iconic working fluids such as the air and dry gases found in potential industrial and medical applications including barometry, flow calibrators/gas-flow instrumentation, HVAC, sleep apnea equipment, pneumatic controls and ventilation/airflow monitors.
During a teardown of the iPad Air and Microsoft Surface Pro 3 at the Medical Design & Manufacturing Show in Schaumburg, Ill., an engineer showed this "inflammatory" video about the dangers of maliciously mishandling lithium-ion batteries.
Science fiction author Isaac Asimov may have the best rules for effective brainstorming and creativity. His never-before-published essay, "On Creativity," recently made it to the Web pages of MIT Technology Review.
Much has been made over the potentially dangerous flammability of lithium-ion batteries after major companies like Boeing, Sony, and Tesla have grappled with well-publicized battery fires. Researchers at Stanford University may have come up with a solution to this problem with a smart sensor for lithium-ion batteries that provides a warning if the battery is about to overheat or catch fire.
In this new Design News feature, "How it Works," we’re starting off by examining the inner workings of the electronic cigarette. While e-cigarettes seemed like a gimmick just two or three years ago, they’re catching fire -- so to speak. Sales topped $1 billion last year and are set to hit $10 billion by 2017. Cigarette companies are fighting back by buying up e-cigarette manufacturers.
