World’s Lowest Power Consumption Accelerometer with Embedded Algorithms

 

Ithaca, New York, November 2008 – Kionix has announced the expansion of its digital-output, tri-axis accelerometer product line with the KXTE9 product series. With embedded algorithms for orientation and activity monitoring, the KXTE9 simplifies the adoption of increasingly-popular, motion-based functionality in consumer electronics while reducing operating power consumption to the world’s lowest levels for such feature-rich products.

 

The advanced, orientation-detection feature of the KXTE9 reports changes in landscape, portrait, face-up, and face-down conditions. This sophisticated, embedded algorithm eliminates the need for continuous data collection and complex calculations by a microprocessor. Accordingly, the KXTE9 enables the implementation of screen rotation—such as that found on some high-end mobile phones— into any handheld device. With a few adjustable parameters, the screen-rotation algorithm can be optimized for an intuitive user experience ...

A Contactless, High-resolution Magnetic Encoder IC for Automotive Applications

 

Unterpremstaetten, Austria - austriamicrosystems expanded its magnetic rotary encoder portfolio with the AS5145, a 12-bit encoder IC especially designed for the growing demands in automotive. The AS5145 is a contactless, complete system-on-chip magnetic rotary encoder for accurate angular measurement over a full turn of 360° with a resolution of 0.0879° = 4096 positions per revolution. This digital angle data is available using a simple serial interface or as PWM signal. In addition, an incremental quadrature output mode with an improved interpolation algorithm can be enabled and permanently programmed with a resolution of 10 up to 12 bits. Due to the higher noise performance the accuracy is further improved ...

Piezoelectric High-temperature Pressure Sensor for Monitoring Cylinder Pressure

 

Kistler's new piezoelectric Type 6351A1 offers a high-temperature M5 size pressure sensor with in-line charge amplifier and a robust, steel-sheathed cable. The minimal dimensions of this sensor make it ideal for compact engines offering extremely limited mounting room. In addition to conventional mounting in the cylinder block, the sensor can even be integrated into engine components such as gas injection valves. With the new PiezoStar® crystal the sensor, despite its miniaturization, is very sensitive and can be used for knock control as well as monitoring thermodynamic parameters. The service life of the new Type 6351A1 is comparable with the tried and tested M10 monitoring sensor Type 6613C ...

Accurate Pressure Transmitters for Measurement on Natural Gas Compressors

 

Telford UK - The Gefran XPSA pressure transmitters use a bonded strain gauge measurement technique, developed by Gefran to produce a rugged, compact sensor with a stainless steel diaphragm. The XPSA series offers a high accuracy and stability (0.1% of FS) and fast response (<1msec) unit, that is insensitive to vibration. With intrinsically safe hazardous area approvals, the Gefran XPSA is particularly suited to the monitoring of natural gas pressure in distribution plants, compressor units and pressure reduction stations, as well as for general use on chemical plants. The standard ranges available cover from 0 - 50 bar, up to as high as 0 - 1000 bar, with most standard process connections available, such as G1/4, G1/2, 7-16UNF and 1/4NPT ...

Hall-Effect Rotary Position Sensor Endures Harsh Conditions and Enhances Precision

 

Honeywell has introduced 17 new RPN Series Hall-Effect Rotary Position Sensors that simplify customer use by providing the inputs, outputs and voltage ranges needed for nearly any control system.

 

Eight operating ranges up to 360° give customers greater control system accuracy by allowing them to select a range more closely suited to their application. Five supply voltage outputs (5 Vdc to 30 Vdc) and eight output configurations (mA or Vdc) improve compatibility with a variety of control systems. Linearity as low as ± 0.35° provides customers with increased measurement precision. This precision can be essential depending on the application. Two connector choices (AMP Superseal, Deutsch) satisfy customer connection requirements. The RPN Series' products also share the same footprint, eliminating special recalibrations and simplifying use ...

RFID Time and Temperature Recording IC Saves Medicines and Lives

 

Dresden, Germany - November, 2008 - ZMD AG, has launched the ZMD41211, a multifunction temperature logger and smart-label radio-frequency identification (RFID) integrated circuit (IC). Using the ZMD41211, logistics customers can precisely monitor and record temperature and humidity throughout the shipping process. This is a key capability, since many materials can tolerate temperature fluctuations but only for a limited time. ZMD's new RFID IC records time as well as temperature, so shippers can determine the total exposure. This avoids the necessity of discarding products that may only have been briefly exposed to temperatures outside the permitted range.

 

The ZMD41211 is cost-effective for all types of temperature or spoilage-sensitive products, from vaccines to vegetables. It has a built-in timer function that allows the user to customize the monitoring frequency. An on-chip temperature sensor and EEPROM allows the logging of time and temperature values during the entire transportation process. The RF interface is easy to use. ZMD's new temperature logger complies with ISO 15693 RFID technology and can be read and programmed with existing standard compliant systems ...

Multichannel Data Acquisition System

 

Many industrial and research application need to acquire physical phenomena (force, weight, displacement, pressure, temperature etc.) with transducers and sensors, to show wave forms on a screen, to print graphs and to save measured data. DS Europe has been producing sensors and transducers for 30 years and is proposing series DSLab multi channel data acquisition system to satisfy these needs. The DSLab system includes transducers with compatible analog signals (mV differential, 5 V, 10 V, 4-20 mA) that measure and transmit their analog signals to a mod. SAP digitizing electronics with up to 8 pcs max. input channels. Mod. SAP acquires the analog signals with high resolution (24 bit max. A/D converters), high sampling rate (up to 1 kHz max. allow to acquire slow and fast values) and digitally retransmits the acquired values by means of CAN Open bus net to the computer USB port where DSLab acquisition software is installed ...
