Signal Conditioner handles smart sensors.

Press Release Summary:




Three-channel Model 433 amplifier card works with single-ended piezoelectric and ISOTRON(R) accelerometers, remote charge converters, and i-TEDS IEEE P1451.4 smart sensors. Microprocessor provides fast data transfer with reliability. Gain is programmable from 0 to 1000 while accuracy is 0.5% at 1 kHz for gains greater than 1.0. Card plugs into company's Model 4990 and 4998 racks, and can be remotely controlled via Ethernet or RS-232 interface.



Original Press Release:



Model 433 Three-Channel PE/ISOTRON(R) Signal Conditioner has i-TEDS "Smart" Capability



SAN JUAN CAPISTRANO, Calif. - March 29, 2002 - Endevco Corporation's new Model 433 is a three-channel piezoelectric (PE) and ISOTRON(R) (IEPE/voltage-type) signal conditioner amplifier card that is rack-mounted. The card is used with single-ended PE and ISOTRON accelerometers, remote charge converters, and the newly developed i-TEDS IEEE P1451.4 "smart" sensors.

This unique combination of i-TEDS sensors and intelligent electronics provides a winning solution for modal test labs. Data entry errors are virtually eliminated, and signal conditioning set-up time is minimized. i-TEDS sensors contain all pertinent data, which automatically loads into a software database with a single mouse click. Each Model 433 card has an independent microprocessor, providing fast data transfer with increased reliability. Gain is programmable from 0 to 1000 while accuracy is ±0.5% at 1 kHz for gain >1.0.

The three-channel card is designed for use with Endevco's Model 4990 and 4998 racks. The 4990 rack is remotely controlled via Ethernet or RS-232 interface and holds up to 16 of the 4xx series of amplifier cards. The 4xx series amplifier card family includes (1) Model 428 dual-channel PE/ISOTRON(R) amplifier card with isolation, (2) Model 436 three-channel non-isolated bridge amplifier card, and (3) Model 482 eight channel i-TEDS amplifier card. The Model 4998 rack is a low-cost, space saving option that holds up to four OASIS-4XX cards, and up to four Model 4998 racks can be linked to one RS-232 COM port.

Endevco is the world's leading designer and manufacturer of dynamic instrumentation for vibration, shock and pressure measurements. The company's comprehensive line of piezoelectric, piezoresistive, variable capacitance, ISOTRON(R) and force balance accelerometers are used to solve measurement problems in a wide variety of industries including aerospace, defense, automotive, medical, industrial and marine. Other Endevco products include pressure transducers, microphones, electronic instruments and calibration systems.

Endevco is a subsidiary of U.K.-based Meggitt PLC, an international group of companies renowned for their specialized engineering skills.
