How current sensing impacts electric vehicles: part 2
Part 1 of this blog addressed current shunts and Hall-effect sensor designs. This part discusses current transformers and new technology options, such as magnetoresistance and diamond quantum sensors. One of the significant issues in today’s electric vehicles (EVs) is the ongoing evolution of technology, with the standards evolving as well. In the 100+ years that […]
How current sensing impacts electric vehicles: part 1
The need to transition from gasoline and diesel (fossil fuels) powered vehicles to electric vehicles (EVs) to reduce carbon dioxide levels has revealed many controversial issues. Common issues include implementation timing, required infrastructure (including fast-charging multi-vehicle systems), legislated rather than consumer-based adoption, ongoing system enhancements, and new critical raw materials sources. Current sensing technology is […]
Current sensors and current shunt monitors for common-mode voltages and temperatures
Texas Instruments debuted new current sensors to help engineers simplify their designs while improving accuracy. Designed for a broad range of common-mode voltages and temperatures, the new products include a lowest-drift isolated Hall-effect current sensor for high-voltage systems and a portfolio of current shunt monitors that eliminate the need for an external shunt resistor for […]
ON/OFF current sensor from Carlo Gavazzi
CARLO GAVAZZI has announced the addition of a compact ON/OFF current sensor, which is ideal for monitoring of critical loads such as fans, water pumps, lighting, and motors. The EISH Series can detect current as low as 200 mA AC and up to 60 Amps AC, making it optimal for applications in a variety of […]
4 to 20 mA current loops made easy
by Edward E. Herceg, VP and CTO, Alliance Sensors Group For analog sensor data transmission, a 4-20 mA current loop is a very common method to convey the sensor data acquired. Sensors or transducers are usually designed to measure a range of values of the measured parameter, which is known as the measurand. The measurand […]
Electronics that operate in extreme heat to 800°C
Extreme environments require electronic systems capable of surviving beyond the MIL-STD operating temperature range of -55°C to +125°C. This FAQ series will go to extremes and look at super hot electronics (up to 800°C) and cryogenic electronics. Part one of this series looks at electronics that operate in extreme heat. Part two will look at […]
Kelvin 4-Wire sensing solves the “IR Drop” problem
Novice engineers usually don’t learn about this problem and its solution in school, but “practicing” ones learn about it soon enough! Problem: I need to determine the change in resistance of a low-resistance sensor located many meters away. My plan was simply to apply a known voltage across the thin-wire sensor leads and measure the […]
