Sensors Web Portal has Opened the First Sensors e-Shop in the Net


January 6, 2003, TORONTO, ON – The sensors e-Shop for B2B and B2C e-commerce has been opened at Sensors Web Portal (http://www.sensorsportal.com/HTML/E-SHOP/e-shop.htm).


“It is the first e-Shop at a specialized vertical web portal devoted to sensors, transducers and sensor instrumentation”, said Jim Stewart, sales manager of Sensors Web Portal Inc. “The e-Shop will allow visitors to Sensors Web Portal to compare the price and technical performance of sensors and measuring instruments from different vendors. The availability of side by side comparisons of products will yield savings in time and money for users as they can select the product that best meets their needs and purchase it in one on-line visit. The efficiency of an easy one-step operation will attract many new customers to this burgeoning sales channel. Sales of products on-line at Sensors Web Portal, promises to reduce vendor costs for product distribution and also has the potential to deliver savings in marketing and procurement.


Many manufacturers have e-Shops at their own corporate web sites, but prospective customers are often unaware of this fact. To generate a high traffic level to these on-line stores requires considerable investment in promotion with no guarantee of an adequate return on the funds invested. Sensors Web Portal represents a different starting point. It is a well-known, high traffic web portal specifically focused on the sensors and transducers industry. Standard search engines like Yahoo!, Google, AltaVista, etc. return enormous numbers (sometimes millions) of web results which requires that the user spend excessive amounts of time sorting and filtering to find the desired information. Customers start their search for sensors information from the Sensors Web Portal gateway because the data returned is classified in a manner consistent with the vertical focus of the site. As a hub of the sensors market, Sensors Web Portal is the ideal environment for selling on-line.


“The first products at our e-Shop are being sold in association with Amazon and we welcome any vendors interested in exploring this opportunity further to contact us.” - added Mr. Stewart.

Piezoresistive Accelerometer Designed for Crash and Flutter Testing Applications

SAN JUAN CAPISTRANO – January 8, 2003 – Endevco’s new Model 7268C is a miniature piezoresistive accelerometer (10 x 10 x 13 mm) that employs advanced micro-machined (MEMS) sensors with integral mechanical stops for ruggedness and years of reliable service. This 3-axis accelerometer is designed for applications that require minimal mass loading, such as crash testing and flutter testing, and meets SAE J211 specifications for anthropomorphic dummy instrumentation. The Model 7268C’s broad frequency response extends down to DC (steady state) acceleration, allowing it to measure both long duration transients and short duration shocks.


Based on Endevco’s proprietary sensor design, the Model 7268C offers high output and high resonance frequency. The sensor has minimum damping, thereby producing no phase shift over the useful frequency range. An operating temperature of 0F to +150F (-18C to +66C) ensures high performance even under the harshest testing conditions. Two active arms and two internal precision fixed resistors provide shunt calibration, while internal diodes furnish electrostatic discharge protection. A 12 wire integral cable is also included. The Model 7268C is the replacement for the Model 7268B and is available in two acceleration ranges, 500g or 2000g full scale.

In-Line Charge Converters for Conditioning High-Temperature,

Charge Mode, Piezoelectric Sensors

NY - Models 422E35 and 422E36 In-Line Charge Converters from the Electronics Division of PCB Piezotronics, Inc., serve to convert charge mode piezoelectric sensor signals into low-impedance voltage signals for input to readout, recording, and analysis instruments. These units are designed for use with high-temperature piezoelectric acceleration, pressure, and force sensors, as they will accept source resistances as low as 10k ohm.


The insulation resistance of a charge mode sensor will be reduced as its temperature is raised. At temperatures above 400°F (204°C), this resistance could be lowered to a level that may cause typical charge converters to shut off. With the PCB 422E35 and 422E36 models, this situation is avoided because the converters are specifically designed to accommodate low source resistances.


The In-Line Charge Converters operate with ICP sensor signal conditioners or readout devices which have an ICP sensor input, and are typically used in harsh, high-temperature environments such as vibration monitoring and testing of turbines, engines, and exhaust systems.

IEEE1394-EVB for FillFactory CMOS Sensors

The IEEE1394-EVB can be used with all the standard products- IBIS4, IBIS5, FUGA1000, STAR250 and STAR1000. It is an one-board solution with three functionalities: controller, memory and fire wire interface. There's 32KB memory on the fire wire interface and 512MB SDRAM on the whole board. The transfer speed is approximately 5Mb/s. For IBIS5 it will be capable of sending 2 images/s out. An other possibility is store the image on the SDRAM.

Transducer Signal Conditioner Designed for Multi-Channel Applications

SAN JUAN CAPISTRANO, Calif. – January 8, 2003 – Endevco Corporation announced the availability of the enhanced Model 482B rack-mounted signal conditioner. The eight-channel amplifier card communicates with newly developed SMART ISOTRON® (IEEE P1451.4 TEDS) accelerometers, yet provides backwards compatibility for use with other Integral Electronic PiezoElectric (IEPE) transducers and Remote Charge Convertors (RCC). The 482B is designed for multi-channel modal testing on large structures such as airplanes, spacecraft, automobiles, bridges and heavy machinery.


Endevco’s enhanced signal conditioner is part of the company’s Optimal Architecture Sensor Interface System (OASIS 2000) product line. OASIS 2000 allows the interface of multiple sensor types by using the 400 Series family of signal conditioner cards, all housed in a 16-slot, 19” rack (Endevco Model 4990). 400 Series cards can be mixed or matched in any combination, giving maximum flexibility to customize any system configuration. Specifically, up to 16 Model 482B cards can be used in the Model 4990 rack, providing a powerful 128 channels of flexible, intelligent signal conditioning at a low per-channel cost.


The combination of SMART ISOTRONS and intelligent electronics make the 482B ideal for use in modal test labs. TEDS accelerometers contain all pertinent data, which is automatically loaded into a software database at the click of a button. Data entry errors are virtually eliminated and signal conditioning setup time is minimized. Each Model 482B card also has an independent microprocessor, providing the fastest means of data transfer possible with increased reliability.


The signal conditioner features a programmable gain of 0 to 100 with an accuracy of +0.5% at 1 KHz for gains greater than 1. The 482B also has built-in, selectable Butterworth 2-pole low pass filter corners at 100Hz, 1KHz, 5KHz and broadband. In addition to an Open/Short ISOTRON Sensor fault detection, the signal conditioner has gain autoranging, digital electronic output channel identification, and a frequency response of 0.015 Hz to 100 KHz (-3dB corners).


Sensor-specific digital read/write data is in the form of the PIEEE-1451.4 Transducer Electronic Data Sheet (TEDS). TEDS data includes model number, serial number, transducer sensitivity, manufacturer, and date of last calibration. Endevco’s Model 4990 rack provides the communication link (Ethernet or RS-232) between the PC and the Model 482B card. The system controlling program is a Windows® based application software providing an extremely user-friendly interface.
