Sensor Technology is created a torque transducer for power take-off (PTO) shafts in agriculture, construction and industry. Called SGR570, it is a range that will cover 1Nm to 2kNm. Sealing will be to IP65, and there will be “analogue and digital outputs, the same as the SGR520, configuration software, PC connectivity, user-configurable limits and an anti-rotation eye hook”, according to ...

Kaman Precision Products has introduced a high-reliability version of its KD-5100 eddy current distance measuring module, intended to be used for nanometre resolution feedback where moving mirrors are used to steer lasers, for example. Bandwidth is 0 to 5kHz. The module works with pairs of eddy current coils, connected by flying leads, positioned on the mirror assembly so that the ...

Researchers at UK universities have developed a wearable ‘sticker’ that can monitor and detect changes in people’s breathing rates. The non-invasive sensor-based system – using a capacitive sensor – can efficiently discern changes even when not in direct contact with the skin. It represents an alternative to chest-band or face mask systems, which can be uncomfortable for use over long ...

Melexis has brought out a pressure sensor which measures both gas and liquid media from 2 to 70 bar, all within a compact SO16 package. The MLX90833 is a factory-calibrated device which provides absolute pressure readings with a LIN digital output, simplifying integration for heat pump manufacturers. The increasing number of heating and cooling modes in heat pumps, particularly EVs, is ...

Asahi Kasei Microdevices (AKM) is shipping has its new InAs Hall element, the HQ0A11. HQ0A11 features AKM’s smallest and thinnest package size for an InAs-based Hall element, measuring 0.8 x 0.4 x 0.23 mm. It achieves an 85% reduction in volume compared to the previous model of HQ0811 in the high-sensitivity HQ series. It is expected that HQ0A11 will contribute ...

At Electronica 2024 we caught up with Lisa Trollo, ST’s Marketing Communication Manager, as part of our promotional coverage for the event. In this interview, she discusses ST unveiling its new biosensor family with ST1VAFE3BX. It is the first dual-function biosensor combining a vertical analog front-end (vAFE) for detecting biopotential signals and a 3-axis ultralow-power accelerometer for motion tracking. Biopotential ...

At Electronica 2024 we caught up with Norbert Breyer, Director Marketing & Product Manager at ScioSense, as part of our promotional coverage for the event. As a specialist in environmental and flow sensors, ScioSense is helping companies use the planet’s vital resources more sustainably to ensure we all live healthier lives. Its sensors are designed to be small, smart, and ...

Melexis is aiming at electric motors with family of angle-sensing absolute magnetic encoder ICs that can work at high speed and typically deliver 1° accuracy or better. “By detecting the three components of the magnetic flux density – Bx, By and Bz – and measuring the differential magnetic field in the z-axis, MLX90382 enables tracking of absolute angle position and ...

Melexis has announced a magnetism-based current sensor that needs no ferromagnetic core, for measuring currents through power PCBs and busbars (see diagram). MLX91235 is gradiometric, taking a differential magnetic field measurement with two internal sensing elements “ensuring stray field effects are eliminated”, according to the company. It is aimed at automotive and other e-mobility applications and, as such, has been ...

Cambridge Integrated Circuits has introduced a non-contact rotary position sensing IC that can operate at 66,000rpm producing 1,000 quadrature cycles per revolution, or can work at resolutions up to 16,384AB cycle/rev. Edge rate up to 4.5MHz are possible, equating to 4,170rpm at 16bits, and up to 33,000 position sample/s. “33,000 measurements per second is over six times faster than our ...
