Measuring the Hall effect
The Hall effect, first described by Edwin Hall in 1879, results in an electrical output when a thin metal plate is immersed in a magnetic field of sufficient strength. The magnetic field must be perpendicular to an electrical current conducted through the plate. The Hall effect voltage potential depends upon the strength of the magnetic […]
OpenVPX backplanes designed for horizontal-mount enclosures
New OpenVPX backplanes are designed for horizontal-mount enclosures. The horizontal-mount backplanes can be placed into 1U-4U tall 19-in rackmount OpenVPX enclosures. They provide enough space to have three 3U slots or one 3U and one 6U slot side-by-side. So, a wide range of configurations and size options are available. The backplanes are typically designed to […]
NI CEO: COVID-19 on day one
NI CEO Eric Starkloff’s first decision was what to do about COVID-19 the night before he took over on February 1, 2020. Since then, he’s seen the opportunities in communications resulting from the pandemic. How would you like to take on a new leadership role just as a pandemic takes hold? That’s what Eric Starkloff […]
Versatile development enclosures support SOSA, OpenVPX
Versatile backplane/chassis configurations are geared for 3U and 6U OpenVPX and SOSA development. The versatile development enclosures start with a line of single-slot power and ground backplanes in various 3U and 6U configurations. This includes VITA 65 (standard VPX), VITA 66.4 (VPX with optical), and VITA 67.3 types (VPX with RF). The backplanes can be […]
USB power sensor characterizes Wi-Fi 6 devices
The Boonton RTP5008 Real-Time Peak USB Power Sensor enables characterization of Wi-Fi 6 devices in the newly allocated 6-GHz band (5.925 to 7.125 GHz). The RTP5008 offers industry-leading performance with wide video bandwidth, fast rise times, fine time resolution, narrow minimum pulse widths, high pulse repetition rates, and superior measurement reading rates. The RTP5008 can […]
Micro-Measurements releases Advanced Sensors Technology CEA and EA
Micro-Measurements, a Vishay Precision Group (NYSE: VPG) brand, announced the successful integration of Advanced Sensors Technology in its new CEA-Series and EA-Series strain gages. Designed for general purpose, static and dynamic stress analysis, the new CEA and EA strain gage sensors are ideally suited for a broad range of applications including structural health monitoring, autonomous vehicles, […]
The hot and cold of thermocouples
The common temperature probe contains a thermocouple consisting of two dissimilar metals welded together to form an electrical junction. A voltage that varies with temperature is generated. Slightly less accurate than resistance temperature detectors (RTDs), thermocouples cover a wide temperature range and respond quickly. Combinations of different metals create different voltage responses. All dissimilar metals […]
Lasers and how to measure their output
Laser is an acronym for light amplification by stimulated emission of radiation. Lasers, of course, started out as comprised of discrete components. The most basic laser consists of a cylinder containing the lasing medium, a material that emits light when exposed to an outside source of energy. The gain medium can be gas, liquid, solid […]
Basics of monitoring vs. testing in current, voltage and power
Industrial measurements often must take place via specialized transducers sized specifically for the current and voltage swings involved. Will Delsman | NK Technologies Older ammeters worked great when the current flowed at a steady 50 or 60 Hz. Consider the antique GE model 8AK1A1AF. I have one that remains accurate after decades of use and […]
