The Labfacility L300 Pt100 temperature alarm / on-off controller can be used in conjunction with a PC to provide accurate monitoring and alarm or on-off control of up to 8- zones simultaneously. It can also be used as a stand-alone instrument without the need for a PC. The PC software supplied with the instrument allows control, configuration, measurement, logging, charting, alarm & relay configuration and calibration functions via a PC. The in-built self-calibration facility of Pt100 ranges ...
NASA is experiencing a few challenges when it comes to the accurate collection of data from Earth and space. They might need help from the private sector and regular citizens to solve the problem. NASA citizen science project app on a phone. (Image via citizen science center)   When it comes to precision in data, many will agree that the National Aeronautics and Space Administration must be the most reliable place to get it from. However recently the agency is finding it hard to always mai ...
Introduction   My old Kewtech voltage probe came to bits on me, so as it was no good to me anymore, I took the liberty of having a look inside it as detailed in an earlier blog.   Uh-oh broken my voltage   I have spent a few days looking at a replacement and placed an order with Farnell, that arrived promptly the next day. Unfortunately, they didn't have the proving unit to go with this, so I purchased that from another well known online electronics supplier.   Unboxing ...
A real world example that uses the electronic load to automatically measure the efficiency of a switch mode power device: The LabVIEW controls a power supply and the DC load. It will test the efficiency for more than 800 combinations of input voltage and output current. The results are logged to a spreadsheet and can be used to graph the behaviour of the device under test.   The Setup  The device under test is a DC to DC switcher that I got from element14 for a Road Test: TI SW ...
This blog focuses on the LCD for the electronic load that peteroakes, jc2048 and jancumps are designing.   The post shows what's displayed on the screen and how that info is retrieved..   The Layout  The LCD shows the mode, status, set and measured values.       The Display  The optional display is a boosterpack, Product Link. The load doesn’t need the display to operate. It was added for two reasons: it served as a debug tool at the beginning o ...
A Japanese research team created an artificial skin that could help improve the quality of life. (Image via University of Tokyo)   From a pacemaker for the brain that helps patients with memory to an artificial limb that teach the patient how to command voluntary movements, medicine keeps copying engineering to improve lives. Or, maybe it is engineering that is evolving to provides better tools for the medical practitioners. This time it is the electronic chip that is crossing from electro ...
Peter, Jon and I are building a Programmable Electronic Load. In this series of blogs I'm building a LabVIEW library of reusable components   In this fifth article: Enable and Disable the Input.   LabVIEW has a set of blocks to build flows with serial communication devices. Those blocks work well with our instrument. However, inspired by what many instruments do (in this case, the BK Precision 85xx series), I'm creating more abstract blocks.   Input Control Block  This ...
Exercising and fun have merged with the new health tracker: a hula hoop that track your data while the user is having fun spinning the hoop around his waist. Pitcured, Vhoop segments and bag. (Image via Vhoop)   Every day researchers are looking for ways to make life easier and more exciting. Given the hype around being and staying healthy, the best and biggest target market for a product currently would be the health-conscious people: from people who want to lose weight to those who want ...
Peter, Jon and I are building a Programmable Electronic Load. In this series of blogs I'm building a LabVIEW library of reusable components   In this fourth article: Set the constant mode function to Current, Voltage, Power or Resistance   LabVIEW has a set of blocks to build flows with serial communication devices. Those blocks work well with our instrument. However, inspired by what many instruments do, I'm creating more abstract blocks.   Function Set Block  This b ...
Peter, Jon and I are building a Programmable Electronic Load. In this series of blogs I'm building a LabVIEW library of reusable components   In this third article: Close all instrument resources   LabVIEW has a set of blocks to build flows with serial communication devices. Those blocks work well with our instrument. However, inspired by what many instruments do, I'm creating more abstract blocks.   Close Block  This blog is easy. It closes all resources assigned to ...
Peter, Jon and I are building a Programmable Electronic Load. In this series of blogs I'm building a LabVIEW library of reusable components       In this second article: Reading the the instrument's measurements   LabVIEW has a set of blocks to build flows with serial communication devices. Those blocks work well with our instrument. However, inspired by the example for (in this case) the BK Precision 91xx family, I'm going to create more abstract blocks.   Read Ou ...
