Pepperl+Fuchs has extended its portfolio to include reduction factor 1 sensors with IO-Link, providing users with even more flexibility, additional features, and diagnostic options. Plant designers have long had to use different types of sensors or deal with time-consuming reconfiguration when tasked with detecting objects made of different types of metal. Standard inductive sensors can […]
How can sensors make a smart ball?
At Sensor Expo 2018 in San Jose, CA, an expert from NXP Semiconductors describes the Internet of Things (IoT) smart ball demo that NXP had in its booth. Sensors in the ball provide real-time data and the system can publish the data to the cloud using IBM Bluemix Services. The data includes 3-axis measurements from […]
What’s new in magnetic sensors?
At Sensors Expo 2018, Evgeny Burmistrov, an engineering manager from Crocus Technology discusses the company’s tunnel magnetoresistance (TMR) magnetic sensor technology. For sensing, TMR is used in number of different applications. Crocus is advancing its TMR capabilities toward linear and 2D sensing. Burmistrov shows the response of a TMR sensor measuring the speed of a […]
What’s new in magnetic position sensors?
At Sensors Expo 2018, Vinicius (Vinnie) Cardoso, a field application engineer at Melexis, demonstrates the capabilities of the company’s magnetic position sensors. Using an extremely eye catching 3-D LED structure, he shows how the MLX90333 Triaxis® position sensor indicates the position of a magnet. With red and blue LEDs indicating the north-south poles of a […]
What’s new in sensing for robotic control?
At Sensors Expo 2018, Tatsuya Yuhara, from TDK Corporation demonstrates how to control a remote robotic arm with the company’s TAD2140 tunnel magnetoresistance (TMR) sensor. Following the arm and hand motion, the TMR sensor allows Yuhura to easily pick and place an object remotely. This kind of operation is common in hazardous operations where the […]
What’s new in magnetic sensors?
At Sensors Expo, Wayne Seto, Senior Director of Product Marketing from Crocus Technology, discusses the company’s tunnel magnetoresistance (TMR) magnetic sensing technology. For sensing, TMR is used in number of different applications. Wayne demonstrated several digital latches with omnipolar (CT832DM), bipolar (CT852AN), unipolar (CT832EK, CT832BV, CT832SK and CT811DK) and analog (CT834DR) magnetics. For omnipolar sensing […]
How big is the magnetic sensing market?
Angle, position and current sensing, as well as compasses and even some switches, rely on magnetic sensors. While Hall-effect technology has been a dominant enabler of these sensors, so-called xMR or magnetoresistive/magnetoresistance technologies are playing an increasing role. The x can stand for anisotropic (AMR), giant (GMR) or tunnel (TMR). With these new technologies playing […]
What advanced sensing techniques are used to find lost treasures? Part 2: Electromagnetic induction
Part 1 of this series addressed magnetometry. Another sensing technique used by archeologists and treasure hunters to find objects is electromagnetic induction (EMI or EM). EMI sensing measures the change in mutual impedance between a pair of coils on or above the earth’s surface. Typical EMI instruments use two or more sets of coils, electrically […]
What advanced sensing techniques are used to find lost treasures? Part 1: Magnetometry
While “one man’s trash is another man’s treasure,” the same types of advanced sensing techniques are used both for investigating archeological sites that frequently reveal much about previous inhabitants from their garbage to true treasure hunts for gold, silver, lost gems and more. Among the more commonly used sensing techniques are magnetometry, electromagnetic induction (EMI […]
What types of sensors are used in robots? Part 2 of 2
In addition to the sensors identified in Part 1 of this blog, there are several others required for different types of robots. Chemical, light and color sensors enable the robot to evaluate, adjust and detect problems with its environment. For humanoid robots that can walk, run or even dance (like Dobi, made by Chinese company […]
