High-speed cameras for the UV light spectrum

September 15, 2023 By Redding Traiger

Vision Research has introduced high-speed cameras capable of capturing images in the extended light spectrum of UV, visible, and Near-IR wavelengths. The cameras have over 70% Quantum Efficiency (QE) at 300nm, as well as unprecedented QE at other points of the UV light spectrum, allowing researchers to potentially capture images using just the camera and […]

What sensors does NASA use to monitor Martian weather?

April 5, 2022 By Jeff Shepard

The Mars Environmental Dynamics Analyzer (MEDA) on the Perseverance rover is characterizing the surface weather as well as the dust particle size and morphology. Understanding dust behavior is a key to predicting Martian weather. Dust influences Mars’ weather the way that water controls Earth’s weather. Two of MEDA’s weather-related goals are: determination of the destructive […]

What is the difference between variable reluctance and eddy current speed sensors?

May 19, 2021 By Randy Frank

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

October 13, 2020 By Mike Santora

SICK

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

March 26, 2018 By Mike Santora

Novotechnik-IOlink-4800

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?

November 29, 2017 By Randy Frank

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?

May 22, 2017 By Randy Frank

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 […]
