TDK Corporation expands its tunnel-magnetoresistance (TMR) angle sensor portfolio with the launch of the TAS4240 TMR-based angle sensor for automotive and industrial applications. The TAS4240 comes in a compact TSSOP8 package and provides two redundant analog single-ended SIN/COS outputs. The sensor enables precise angle measurements in applications where high performance is needed and space is […]
Resistance/resistivity
RTD probes come in 3-wire and transmitter models
Tel-Tru Manufacturing has introduced an advanced line of 3-wire industrial RTD assemblies and temperature transmitters. These probes are designed for the applications common to food and pharmaceutical processing, refineries, chemical plants, water and wastewater facilities, breweries, dairies, HVAC, and the OEMs serving them. The temperature transmitters provide 4-20 mA or HART outputs. Standard RTD assemblies […]
Modular instant and metal contacts for pneumatic connections
Mencom announces an improved version of the MIXO modular pneumatic connection system that uses a new self-extinguishing thermoplastic insert and metal contacts. The new MIXO system not only allows more frequent mating cycles for compressed air distribution systems but also guarantees better mechanical resistance, increased airflow for transmitting dry and compressed air in pneumatic systems. […]
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 […]
Electronics that operate in cryogenic cold
The first part of this FAQ series looked at “electronics that operate in extreme heat” (up to 800°C). This FAQ delves into the opposite end of the temperature spectrum and heads toward absolute zero. There are several existing cryogenic electronics applications, including superconducting quantum interference devices (SQUIDs) for measuring extremely subtle magnetic fields, microwave preamplification, […]
What advanced sensing techniques are used to find lost treasures? Part 4: Resistivity measurements
This series has previously addressed magnetometry, electromagnetic induction and ground penetrating radar. Another sensing technique frequently used by archeologists and treasure hunters to find objects involves resistivity measurements. Unlike other sensing techniques, resistance measurements involve inserting metal probes into the ground rather than non-invasive surface measurements. Since electrical currents are conducted through the soil by […]
