DC Transducers for Current Applications up to 400A

The DCT series of DC current transducers combines a Hall Effect sensor and signal conditioner into a single package for use in DC current applications up to 400A. Designed to be compatible with most PLCs, data loggers and SCADA systems, the DCT series features jumper-selectable current input ranges and industry standard 4-20 mA or +/- 10 VDC outputs. For example, the 400A DCT400-42-24-S has  0-200A, 0-300A or 0-400A jumper-selectable input ranges.

Split-core or fixed-core models are available.

Motion Sensor Market Growing 20.3% Annually

All those accelerometers, gyroscopes and compasses and in mobile and gaming applications add up quickly. In fact, in the new report “Motion Sensors for Consumer & Mobile Applications,” Yole Developpement researchers expect 2009’s sales of $847M to reach $2.56B in 2015 – a 20.3% annual growth rate. Yole projects that many applications will employ 3-axis accelerometer and 3-axis gyroscope combined into a single package within 2015. Compasses (magnetometers) now popular in handsets will add gaming and digital still cameras (DSC) for advanced geo-tagging to the list of applications driving their usage. Over 50 companies targeting these applications will make the product offerings quite interesting and competitive.

Using Integrated Giant Magnetoresistance Sensors for EVs and HEVs

At the SAE Hybrid Vehicle Technologies Symposium in Anaheim, CA, Dusan Gravoc, senior manager and Head of Product Marketing for Infineon Technologies AG shows how an iGMR sensing IC can replace incremental encoders and resolvers in electric and hybrid vehicles. Infineon’s TLE5012 is housed in a small SO-8 package that targets integration in electrically commutated motors.

Measuring Hydraulic Cylinder/ Actuator Travel and Tank Level

While many sensors, especially those based on microelectromechanical systems (MEMS) technology, get increasingly smaller, some measurements dictate the need for a large or sufficiently long sensor. This is the case when measuring the position of moving machine parts in applications such as paper and pulp mills, injection molding machinery, turbine blades and process level management. These are the types of applications addressed by a new series of sensors from Macro Sensors. The MLW Series of Long Stroke Linear Position Sensors are designed for highly accurately absolute position measurement of displacements up to 1.2 meters.  

The sensors use magnetostrictive technology and operate by transmitting a current pulse through a tube that is reflected by a moveable permanent magnet.  The output signal is based on a time of flight measurement by the sensor that determines the position of the magnet on the tube.

Motion Sensing Monitors Swimming Activity

Using motion sensing technology, FINIS Swimsense Performance Monitor automatically detects and distinguishes stroke types, and records the number of laps swum, total distance, calories burned, lap time, pace and stroke count. The monitor fits in a watchband form factor and uses accelerometers, magnetometers and patent-pending proprietary algorithms to identify the user’s swim. The swimmer simply uploads swim data to the Swimsense Training Log to analyze distance, calories, different stroke types, pace, stroke count and SWOLF (swimming efficiency) score. Designed for fitness enthusiasts and recreational swimmers to elite swimmers and triathletes, they can view their current workout while they swim and up to 14 past workouts/swims on the Swimsense monitor

Three-dimensional Hall Encoders for Industrial Apps

Austriamicrosystems is developing a portfolio of 3D Hall products for automotive and industrial applications. The 3D HallinOne magnetic encoder family provides absolute and highest resolution angular or linear output data.

The AS540x series uses two “pixel-cells” in a differential mode to guarantee robustness against all possible external influences like stray magnetic fields.  In addition, the IC contains an EEPROM to provide maximum flexibility to system designers when programming and linearizing the IC.  The use of this approach extends  the absolute linear position measurement range to 40 mm.
