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 […]
Tester helps check out digital coherent optical modules
The VIAVI 800G FLEX DCO Module provides a wide range of critical test and measurement capabilities that manufacturers need to design and validate pluggable digital coherent optical modules. Native support for both 400G class CFP2 (DCO) and QSFP-DD 400ZR modules is backed by a solid power and thermal cooling environment. Electrical adapters allow testing on […]
How to measure CCD and CMOS image sensor qualities
Today, about 95% of all digital cameras use CMOS image sensors with the rest employing CCDs. From the standpoint of sensor outputs, the main difference between CMOS and CCD sensors is that each pixel in a CMOS sensor has its own readout circuit next to the photosensitive area. In CCDs, charge collected in individual pixels […]
Hand-held pistol-grip camera gives high-quality radiometric images
The FOTRIC 326 Thermal Imaging Camera is a rugged, durable, accurate, and portable handheld heat investigation device, designed for a wide range of equipment and infrastructure thermal diagnostic tasks. The 326 has a large aperture f1.0 IR lens for taking superior quality radiometric thermal images for professional use. TheFotric 326 has a -20 to +650°C […]

A new product line of coaxial packaged tunnel diode detectors are candidates for prototype and proof-of-concept applications used in aerospace and defense, military and commercial radar, test and measurement, SATCOM applications and more. Pasternack’s comprehensive offering includes 26 models of tunnel diode detectors that feature rugged Germanium planar construction and operate over octave and broadband […]
On the “edge” of a revolution
New computing architectures are changing industrial applications, impacting the way measurements are made, data is collected, and how it all gets processed. Miles Budimir Senior Editor The Internet of Things (IoT) continues to influence how industrial systems are designed and built. The core of IoT systems is the collection of data at the device level […]
Flicker spectrometer quantifies light flicker, gauges CIE photometric/radiometric parameter
The GL Spectis 1.0 Touch Flicker Spectrometer is an upgraded version of the handheld Spectis 1.0 Touch Spectral Light Meter. This device can now measure the increasingly important parameter of light flicker in addition to the extensive range of standard photometric and colorimetric values already available. The Spectis 1.0 Touch Flicker Spectrometer is now equipped […]
