Gear tooth speed sensor employs magnetoresistance technology
Allegro MicroSystems, Inc. has introduced a new, state-of-the-art giant magnetoresistance (GMR) speed sensor that measures the rotation of ferromagnetic gears. The ATS19480 speed sensor IC provides a single-channel solution that’s ideal for hybrid and pure electric vehicle transmissions, with use cases extending to two-wheelers, off-road vehicles, and industrial application designs requiring speed-only information. Combining advanced GMR […]
What is the difference between variable reluctance and eddy current speed sensors?
Both variable reluctance (VR) and eddy current (EC) technologies provide contactless speed sensors based on interaction with a magnetic field. A variable reluctance sensor can be thought of as an ac generator with an output voltage proportional to speed. With its self-generating electrical signal, a VR sensor does not require an external power supply. The […]
SICK launches new product for non-contact measurement of speed and length
With the SPEETEC, SICK is expanding its product range for speed and length measurement of objects moving in a linear path to include technology that measures directly on the material surface. The non-contact sensor is able to measure a wide range of web and continuous materials, as well as blanks with an accuracy of just […]
User-programmable angle and speed sensors
Novotechnik, U.S. introduces the IO-Link programming tool for its RFC-4800 Series of touchless angle sensors. This device connects a sensor to a mini USB port of a PC running Windows or newer operating system. IO-Link enables users to program, test and adjust custom offset values to null point, set direction of rotation as clockwise or […]
What functions do sensors provide to drones?
Depending on the type of drone and its function, there can be a few essential sensors or an extensive number of sensors on board. Whether the drones are civilian or military craft, the sensors fall roughly into three categories: Make Them Fly, Make Them Work and Diagnose & Prevent Problems. Make Them Fly An inertial […]
How fast is that thing going?
The need for speed implies the requirement for speed sensing. Speed sensors provide the input and feedback data to monitor and control motors and other rate sensitive linear and rotary applications. For example, the throughput of automated high-speed production lines depends on many parameters but the line speed is an early indication of expected versus […]
No Contact- No Wear Angle Sensors
Novotechnik, U.S. RFC4800 Series of touchless angle sensors can measure angular position up to 360° for a revolution counter and speed measurements. The RFC4800 Series of Hall Effect sensors includes programmable zero point offset, measurement averaging and sign of rotational direction and has a resolution of 14-bits across 360°, repeatability of 0.36° and independent linearity […]
Key standards to know when specifying sensors
by Ted Tomita, Global Product Marketing Manager, Honeywell Sensing & Productivity Solutions Everything from an excavator to a thermostat is getting smarter and the demand for more intelligent and connected systems is driving more demand for sensors in nearly every industry. A report by market research firm BCC Research anticipates the sensor market will grow […]
Bicycle Power Meter Easily Attaches to the Handlebars
Measuring the power (in watts) produced by both legs at a rate of up to 800 times per second, the PowerPod power meter employees several sensors. It includes an accelerometer, air pressure sensor, elevation sensor and speed sensor as well as mounting hardware, and rechargeable internal battery, Micro USB cable. Transmitting data to any ANT+ […]
