In Part 1, we looked at the basic principle and function of the solid-state temperature sensors, as well as the first widely available model, the AD590. Part 2 looks at some application considerations. Q: What are the interface considerations? A: A basic solid-state sensor has a PTAT current-only output. This means that the subsequent circuitry, […]
CMOS image sensor works well in both low and bright-light conditions
ON Semiconductor has introduced a new 1/4-inch, 1.0 Megapixel (Mp) (1280H x 800V) CMOS digital image sensor that captures clean, accurate images with no artifacts in both bright and low light conditions. Its high shutter efficiency and signal-to-noise ratio minimize ghosting and noise effects improving overall image quality. The 3.0 μm pixel AR0144 incorporates an innovative global shutter design that […]
Thermal imaging sensor aids in characterizing critical production equipment
Fluke Corp. has expanded the capabilities of its Condition Monitoring system to include thermal monitoring with the addition of the new Fluke® 3550 FC Thermal Imaging Sensor. Maintenance managers can now collect a more comprehensive variety of key-indicator data — thermal imaging, voltage, current, temperature, and power — on critical equipment to build a real-time […]
What’s the future of augmented reality?
In his keynote address at Sensors Expo 2017, Ori Inbar, co-founder and CEO of AugmentedReality.org tells how augmented reality (AR) is poised for considerable growth. (Excerpt from “Superpowers to Change the World: How Augmented Reality Helps Advance Humanity.”) In 2009, Inbar told a conference audience that in ten years everyone will use AR to experience […]
Current Sense Chip Resistor Kits Offer a Range Of Sizes And Values
Stackpole’s current sense kits are a compact folder containing a variety of 1% tolerance resistance values in a choice of 1206, 2010, or 2512 chip sizes. Stackpole offers values from various series to provide a broad range of values. Higher resistance values are thick film technology, where the lower resistance values will be foil on […]
Put your finger on it: capacitive touch switching
Rather than a physical switch it is now common to use “touch” switches to interface to many types of electronic equipment. Smartphones are an obvious example but touch switches are now in cars, oscilloscopes, ovens and many other types of industrial and consumer electronics. A touch screen will usually be a specialized screen with a […]
Miniature LVDT sensors provide accurate position/path measurements in tight spaces
The new Inelta ILAT Series Miniature LVDT Sensors provide precision measurements of position and path in the range of single-digit millimeters. The sensors of this series are available in Models ILAT 2, ILAT4 and ILAT10 for the exact measurements of ±1 mm, ±2 mm or ±5 mm traveling distances. Owing to their tiny dimensions with […]

H.G. Schaevitz LLC dba Alliance Sensors Group introduces the S1A AC-LVDT Signal Conditioner that offers smart and fast LVDT setup with built-in null indication and simple front panel pushbuttons to set zero and full scale. Engineered to work with the widest range of AC-LVDTs, RVDTs and inductive half-bridge sensors including 3-wire GE LVRTs and GE gas […]
High-performance MEMS capacitive accelerometers feature improved temperature performance, scale factor and bias temperature shifts
Silicon Designs Inc. has announced the global market introduction of six new series of low-cost, high-performance MEMS capacitive accelerometers, in both traditional and smaller footprints. These include the single axis Model 2220 or triaxial Model 2470, featuring aluminum housings and a standard 1 meter integral cable; the single axis Model 2240 or triaxial Model 2480, featuring […]
How does analog to digital conversion impact sensor accuracy?
When an analog sensors’ output is converted to a digital output with an analog to digital converter (ADC), conversion resolution, conversion accuracy, conversion speed or bandwidth, inherent system noise levels, and power consumption are all ADC tradeoffs. Errors due to temperature, supply voltage, linearity, quantizing, and other factors may reduce the accuracy of an ADC […]
