Pressure Systems' newest KPSI™ transducer upgrades allow waterMONITOR transducers to come in an absolute reference pressure format. There is no vent tube or desiccant filter to keep moisture out, making maintenance easier. The baroMONITOR transducers now offer a specialized configuration for collecting barometric (atmospheric) pressure readings, which compensate for absolute level measurement errors caused by changing barometric pressure. Compensation is controlled by K-ware, Pressure Systems' Visual Basic-based application, designed to be intuitive yet comprehensive. The software presents measurement data in a number of formats, both for review and transfer to other software programs. Upgrades are free on Pressure Systems' website at http://rbi.ims.ca/4921-593. Both transducers can be used in groundwater and surface water applications in boreholes, tanks, rivers, lakes, streams and other areas. There are linear, linear averaging, event, logarithmic and other selectable sampling modes. They upload data at 100 scans/sec at a baud rate of 19,200, with a pressure and temperature time stamp. They incorporate internal, non-volatile memory of 2 or 4 Mbytes, and feature up to 15 readings/sec programmable sampling rates. They can each store up to 600,000 level, temperature and time stamp measurements. They have an accuracy of up to ±0.05 percent FS TEB (Total Error Band) over the compensated temperature range of 14 to 104F(-10 to 40C), with a full-scale range from 10 to 692 ft (3 to 210m) H2O. The baroMONITOR has a pressure range of 8 to 16 psia (55 to 100 kPa). The electronics and two replaceable AA batteries are sealed in a ¾-inch stainless-steel or titanium housing.
With major product releases coming from big names like Sony, Microsoft, and Samsung, and big investments by companies like Facebook, 2015 could be the year that virtual reality (VR) and augmented reality (AR) finally pop. Here's take a look back at some of the technologies that got us here (for better and worse).
Good engineering designs are those that work in the real world; bad designs are those that don’t. If we agree to set our egos aside and let the real world be our guide, we can resolve nearly any disagreement.
The Industrial Internet of Things is bringing a previously reluctant process industry into the wireless fold. The ability to connect smart sensors to the Internet has spiked the demand for wireless devices in process manufacturing, according to the new study from ARC Advisory Group.
If you’re developing an embedded monitoring and control application, then you’ll want to take note of the upcoming Design News Continuing Education Center class, “Embedded Development Using Microchip Microcontrollers and the CCS C Compiler."
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
