Unlike an oxymoron (äksəˈmôrˌän: a combination of contradictory words), a (pulse) oximeter (äkˈsimidər) is a sensing technique to measure oxygen saturation in a person’s peripheral (capillary) blood (SpO2). Using pulses in the capillaries of the tested area, the noninvasive measurement helps to evaluate a variety of medical conditions that affect the function of the heart […]
How can touch-free sensing protect public health?
Many communicable diseases, such as viruses and bacterial infections, are transmitted by direct contact with a person who has the disease or with something that person touched. Avoiding contact is an obvious way to prevent spreading diseases. Touch-free sensors allow many frequently accessed functions in restrooms, such as automatic hands-free urinal and toilet flush, hands-free […]
What types of sensors are used in robots? Part 1 of 2
Fully functional human robots, such as those being developed by Boston Dynamics, need numerous sensors to simulate a variety of human and beyond human capabilities. For the human part, the sensors provide the ability to see, hear, touch and move. In general, industrial robots employ sensors for a variety of activities. Some sensors provide environmental […]
New infrared temperature sensor from Balluff
When there is a need to detect objects with high temperatures during various processes in foundries, forging, steel plants, metal stamping, the ceramic industry or glassworks the new infrared temperature sensor from Balluff is the ideal solution. This sensor allows the non-contact monitoring of high temperatures in inaccessible or harsh environments. Housed in a rugged […]
Ruggedized Sensor Packaging
One way to improve a successful sensor and expand its applications is design the package for more demanding environments. This was the goal for Carlo Gavazzi’s PD30ET Series of IP69K Stainless Steel Photoelectric Sensors. With AISI316L stainless steel housings, an IP69K environmental rating and ECOLAB certification, the sensors can operate reliably in applications exposed to […]
Improved Thermal Imaging Temperature Sensors
In a factory, thermal imaging can be an important part of process control and quality assurance as well as provide condition monitoring and fire prevention. To make its sensors even more attractive for these applications, FLIR Systems, Inc. upgraded its A35 and A65 thermal imaging temperature sensors for machine vision. Improvements include: Proven, innovative temperature […]
World’s Smallest Non-Contact Temperature Sensor
Need thermal management and/or temperature monitoring but have minimal space to mount a sensor? Exergen Global’s Micro IRt/c sensor could be the answer. At just 0.75” (19mm) long and 0.25” (6.4mm) in diameter, the infrared (IR) thermocouple fits into extremely tight spaces. The sensor provides accuracy to within ±1%, repeatability of 0.02°F (0.01°C), resolution of […]
Miniature Noncontact Temperature Sensors Get Intrinsically Safe Ratings
Many areas that require temperature monitoring are also hazardous environments. These applications can be addressed with Raytek MI3 Compact Series infrared that are now fully ATEX and IECEx certified for use in Zones 1 and 2 (gas) and Zones 21 and 22 (dust). The sensor, communication box and an Ex power supply are IP65 rated […]
IR Detector Sales to Reach $500M in 2020
According to market research firm Yole Developpement’s report “Infrared Detector Technology & Market Trends 2015,” smart lighting, smart buildings and mobile devices will drive the infrared (IR) detector market to about $500M in 2020. Rather than addressing imaging, the report covers IR sensors that produce a signal to be analyzed for detection. It includes: market […]
Advanced infrared camera at an affordable price from Allied Vision
Allied Vision introduces the new Goldeye G-008 SWIR camera offering unbeatable value for money. The Goldeye G-008 SWIR is packed with all the features and benefits of the current Goldeye camera family, combined with a smaller resolution sensor. As a result, its attractive price lowers the entry barrier into short wave infrared image processing. The […]
