Renesas is claiming “total stray field immunity” for a automotive-grade magnet-free inductive rotation position sensor that works up to what the company describes as “600,000rpm (electrical)”. “We are excited with the response to the inductive position sensing technology we introduced last June for industrial motors, and we look forward to bringing its advantages to automotive customers with the new IPS2550,” said ...

Stress analysis strain gage sensors from Micro-Measurements have pre-attached lead wires to eliminate soldering. The C4A series can be used for simulation and analysis in structural design verification, and can be used for real-time condition monitoring bridges, dams, ships and wind turbines. The sensors are available from New Yorker Electronics. The lead wires are claimed to ensure reliable installation, particularly in ...

Allegro MicroSystems has integrated power, voltage and current monitoring into a single chip with reinforced isolation. Only a handful of resistors are needed to complete the high-voltage interface (diagram right). Called ACS37800, it uses a Hall effect scheme to measure current and external resistors to stand-off the voltage measurement – no opto-isolators, Rogowski coils, current transformers, isolated operational amplifiers nor shunt resistors are ...

Warwick Control Technologies has released a Simulation Kit that allows users to simulate CAN, CAN FD and LIN devices and networks. It can also be used to simulate devices and networks for the SAE J1939, NMEA2000 and CANopen CAN higher layer protocols. These are data-communication protocols typically used for high-speed broadcasting of sensor data, whether they be marine sensors, or ...

Arduino and Seeed have collaborated to produce the Arduino Sensor Kit. Based on the Arduino UNO, the STEM kit is aimed at those getting started with electronics and sensors easier. It contains a Base Shield and ten Grove modules that can be connected either through the digital, analog or I2C connectors on the shield (there are accompanying lessons for the ...

Vishay has release of two high-resolution automotive grade optical reflective proximity sensors that operate down to 20µm for force sensing applications. In use, an infra-red beam is sent out and its reflection detected. Sensing can be from up-close to half a meter away, and can have enough resolution to detect the displacement of a surface for force, push or glove-independent ...

Sensirion has introduced an evaluation kit for its single-use LD20-2600B liquid flow sensors, built around the Swiss company’s CMOSens-branded technology. “Barbed fittings ensure safe and secure integration into the fluidic line,” according to Sensirion, “The straight and unobstructed flow channel design has no moving parts. Medical-grade wetted materials provide chemical resistance and media compatibility.” Flow measurement is bi-directional measurement up ...

Exploiting a quantum principle in a novel way, researchers at the US National Institute of Standards and Technology (NIST) have created a miniature thermometer that works below 1K with errors less that 14mK and a response time of 5ms. Two of the novel temperature sensors (top right, bottom left) are bonded to a chip under test. A conventional wired ruthenium ...

UK-based Teledyne e2v’s Space Imaging division has completed the signing of Thales’ Alenia Space contract for the supply of a specialised image sensor for CO2I and NO2 instruments. The company will supply image sensors and detectors to the recently announced proposal of the European Space Agency to place six Copernicus Sentinel satellite missions in space. As the sensor partner for ...

Most international travellers arriving and departing from Los Angeles International Airport probably haven’t noticed the thermal imaging cameras mounted on what look like streetlights inside the terminal, writes Texas Instruments’ Apoorva Awasthy. But travellers with a temperature above 38°C may be familiar with the new thermal screening technology deployed there this summer. That’s because airport officials are advising anyone with ...
