It’s amazing how much information a sensor’s package conveys regarding its application. American Sensor Technologies, Inc. (AST) AST5400 screams industrial, high pressure. In fact, the wet / wet differential pressure sensor can measure line pressures up to 2,000 PSI. With microelectromechanical system (MEMS) technology as the sensing mechanism, the package uses Krystal Bond Technology to […]
Sense Differential Pressure over a Wide Range in Medical Ventilation Applications
While many medical ventilation measurements are easily handled by a 0 to 500 Pa differential pressure sensor, some require a wider dynamic range. For these applications, Sensirion introduced the SDP2108-R sensor. Based on its SDP1108-R that covers a measurement range of 0 to 500 Pa, the SDP2108-R addresses a range of 0 to 3500 Pa.The […]
Acquire Motion Control and Position Sensing Data with Serial Synchronous Interface Module
Opto 22’s SNAP-SCM-SSI Serial Module provides a communications interface between digital encoders and its SNAP PAC System I/O processors or programmable automation controllers. The module’s two isolated serial synchronous inputs (SSI) simplify acquiring data from optical and mechanical encoders and other types of linear and rotary transducers. Accommodating an SSI clock frequency of up to […]
Legislating More Sensors
If the National Highway Traffic Safety Administration (NHTSA) gets its way, backup cameras will be required on all new vehicles by 2014. Intended to prevent drivers from backing over pedestrians, the Rule could add the cost of camera and display electronics to low-end cars, the most cost-sensitive vehicles. NHTSA data indicates an average of 292 […]
Monitor Energy Consumption to Save Energy
A MEMS Update from Roger Grace
MEMS-Based Gas Meter Flow Sensors
Experts predict that gas meters are poised to undergo the same change as electricity meters for smarter, remote meter reading. In response, STMicroelectronics and Omron have collaborated to provide a complete solution for electronic gas meter flow sensors. The design uses an Omron transducer and a companion analog front-end chip developed by ST. The resulting […]
Highly Integrated MEMS-Based Motion Sensing
Motion sensing is at the heart of several new features in consumer products including cell phone, tablet PCs and games. InvenSense has been a major player in these applications but its newest product family makes motion sensing even easier to design and manufacturer. MPU-6000 product family integrates a 3-axis gyroscope and a 3-axis accelerometer on […]
High Temperature Pressure Sensor Targets Gas Turbine Monitoring
Most pressure sensors are offered in plastic packages and operate in a maximum ambient temperature of 125°C or less. Monitoring the pressure of a gas turbine requires a totally different approach. IMI Sensors Series 176 pressure sensors use a stainless steel housing and piezoelectric sensing technology to tolerate the extreme heat environment (+986°F, +530°C) generated […]
Three-dimensional Hall Encoders for Industrial Apps
Austriamicrosystems is developing a portfolio of 3D Hall products for automotive and industrial applications. The 3D HallinOne magnetic encoder family provides absolute and highest resolution angular or linear output data. The AS540x series uses two “pixel-cells” in a differential mode to guarantee robustness against all possible external influences like stray magnetic fields. In addition, the […]
