Measurements of air velocity, temperature, pressure and humidity combined in one instrument

January 25, 2022 By Lee Teschler Leave a Comment

advanced thermal systems

The iQx instrument system is a device that measures air temperature and velocity, surface temperature, air pressure drop, and humidity. Measurements can be made concurrently or individually. The iQx system is equipped with input ports for up to eight air temperature/velocity sensors, four J type thermocouples, two pressure sensors and one humidity sensor. These can […]

Gauging the thermoelectric effect

December 17, 2021 By David Herres Leave a Comment

thermoelectrics

The thermoelectric effect can be exploited to convert temperature difference to electric voltage or to convert electric voltage to a temperature difference. And devices incorporating the thermoelectric effect can be built and configured to produce heat when voltage is applied. The effect is distinct from resistive (joule) heating, although in actual practice, both effects may […]

How to measure display screen output

November 23, 2021 By David Herres Leave a Comment

The flat display screens of today typically look great. But when it comes to quantifying their output, confusion may reign. There are three main measurement tools used to gauge the output of displays. Before we get into their details, it might be helpful to review the main display technologies we are typically trying to measure. […]

How to look at magnetic domains

August 30, 2021 By David Herres Leave a Comment

magnetic domains

A central concept in magnetism is the domain, discovered in 1906 by Pierre-Ernest Weiss. He theorized that in any magnetically permeable material, a large number of mostly microscopic regions existed as separate walled-off entities. In each of these entities, called domains, the atomic moments align in parallel when magnetized. But the alignment of individual domains […]

Ultrahigh-speed cameras include back-side illumination

August 3, 2021 By Lee Teschler Leave a Comment

vision research

Two new models in the Ultrahigh-speed performance line of Phantom cameras feature a breakthrough CMOS sensor with back side illumination (BSI). The new T3610 and TMX 5010 cameras sustain their image throughput with optimized light sensitivity for high frame rates and sub-microsecond exposures.  Joining the T-Series platform, the Phantom T3610 achieves significantly higher frame rates […]

Measuring the Hall effect

November 24, 2020 By David Herres Leave a Comment

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 […]

Current Digital Issue

A frequency you can count on There are few constants in life, but what few there are might include death, taxes, and a U.S. grid frequency that doesn’t vary by more than ±0.5 Hz. However, the certainty of the grid frequency is coming into question, thanks to the rising percentage of renewable energy sources that…
