Many critical industries, such as pharmaceutical or biotech, require monitoring and validation of the consistently maintained temperature and humidity in warehouses, chambers, refrigerators and/or freezers. Traditional techniques of collecting the data involve wiring to a central collection site or manually transporting either the host or the data logger to transfer its contents. Real-time data transfer using wireless radio frequency (RF) mesh technology simplifies data collection and allows easy verification of the status at critical times.
GE Sensing's Kaye RF ValProbe wireless validation system uses proprietary 2.4 GHz mesh technology to obtain data from up to 100 remote nodes. Mesh technology allows direct transmission to a base station or transmission through other nodes if the direct path has a weak signal to ensure data delivery. This automatically implemented alternative ensures the message always gets through. Encryption protects data transmitted between nodes and the base station. The system's software enables regulatory-compliant text and graph reports, without downloading data to a separate spreadsheet program. With the ability to store up to 10,000 samples per sensor, if RF communication is not possible, critical data is not lost and can be transmitted when RF signal integrity is restored.
The unit's internal relative humidity (RH) sensor has a range of 10 to 95 percent RH with an accuracy of 2 percent RH. In addition to sensing an internal temperature range of -20 to 60C with an accuracy of 0.5C, an external sensor can be used to provide a temperature range of -200 to 200C with an accuracy of 0.1 to 0.3C. An option allows a node to read 4 to 20 mA or 0 to 10V outputs from other sensors, as well as contact switch inputs. Under average usage, the node batteries last about two years. If the unit samples every minute, 8,000 hours (333 days) of battery life can be expected.
Wireless RF mesh technology links the data in real-time directly to a base station or through other remote data loggers to avoid lost data.
Truchard will be presented the award at the 2014 Golden Mousetrap Awards ceremony during the co-located events Pacific Design & Manufacturing, MD&M West, WestPack, PLASTEC West, Electronics West, ATX West, and AeroCon.
Robots that walk have come a long way from simple barebones walking machines or pairs of legs without an upper body and head. Much of the research these days focuses on making more humanoid robots. But they are not all created equal.
The IEEE Computer Society has named the top 10 trends for 2014. You can expect the convergence of cloud computing and mobile devices, advances in health care data and devices, as well as privacy issues in social media to make the headlines. And 3D printing came out of nowhere to make a big splash.
For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This discussion will examine what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
