Heating ventilation and air conditioning (HVAC) applications can use a wide range of full-scale, low-pressure sensors to address the variety of measurements involved in controlling and monitoring for maximum efficiency and performance. In a multilevel building, these measurements could include the use of differential pressure transmitters, a variable airflow volume (VAV) unit, a positive pressure […]
How can kirigami be used for sensing pressure?
If you are like me, you are aware of origami (the Japanese art of paper folding) but need a refresher on kirigami. Unlike origami figures that can only be made by folding, kirigami involves both folding and cutting. Inspired by kirigami, researchers at Texas A&M University developed 3D polymer-based kirigami architectures for microelectromechanical systems (MEMS) […]
Heilind Electronics expands sensor portfolio with P51 series
Heilind Electronics has added SSI Technologies’ MediaSensor P51 Series pressure sensors to its portfolio. Made in the USA, this family of sensors includes bulk micro-machined, absolute, sealed and gauge pressure sensors. MediaSensor P51 pressure sensors are an excellent choice for both harsh and benign media, both due to their stainless steel construction and laser-welded design. […]
How can a carmaker provide more ventilators and/or respirators?
Ventilators and respirators become a critical but limited supply item when a pandemic such as the coronavirus (COVID-19) occurs. Since air pressure and air flow are involved in both, pressure sensors are an integral part of many products. As different aspects of society pull together or respond to the implementation of the Defense Production Act, […]
How can the world solve the global ventilator shortage problem? Pt 5
Ventilator shortages in the US could be on the order of 300,00 to 700, 000 units or more but the estimated supply of existing ventilators in world-wide hospitals was less than 200,000 before the COVID-19 outbreak. A more recent indication is that the US has about 150,000 to 200,000 but still just a fraction of […]
How can the world solve the global ventilator shortage problem? Pt 3
Continued from the university efforts in Pt2. Another example of a university-designed automated AMBU bag-based ventilator was demonstrated by Rice University. Working with Metric Technologies, a Canadian global health design firm, Rice University developed an automated AMBU-based ventilation unit that can be built for less than $300 worth of parts and was based on a […]
What type of packaging exists for sensing pressure?
At Sensors Expo 2019, Tom Nguyen, CEO of DunAn Sensing, explains innovative packaging for silicon microelectromechanical systems (MEMS) pressure sensor die that does not sacrifice performance. To complement its stable silicon MEMS die, DunAn Sensing is investing in packaging that takes advantage of the stability and adds flexibility without giving up performance in the package. […]
MLDX series compensated millivolt-output pressure sensors
Amphenol All Sensors Corp. of Morgan Hill, Calif. now sells MLDX series pressure sensors — which are fully compatible as a drop-in replacement for Honeywell SDX series sensors. The new series offers OEM customers design flexibility and high performance over a wide temperature range … for pressure ranges from 5 inH2O to 100 PSI. The […]
Heilind Electronics adds SSI Technologies to Amphenol sensor portfolio
Heilind Electronics has partnered with SSI Technologies (an Amphenol Company) to bring its customers a broad range of industry-leading automotive and heavy equipment sensor solutions. As an authorized distributor for SSI Technologies, Heilind will offer an extensive selection of level sensors, pressure sensors, digital gauges, speed and position sensors, and other sensing products. The company […]
How does sensor fusion improve an alarm system?
At Sensors Expo 2019, Tanja Hofner, a Principal Hardware Engineer for RF and Sensors in Infineon’s Power Management and Multimarket segment explains the operation of the company’s Integrated Alarm System demo. The demo uses two Infineon sensors: the digital XENSIV IM69D130 microelectromechanical systems (MEMS) microphone and a DPS310 digital barometric pressure sensor as well as […]
