Acquisition support for smart and dumb sensors

An Endevco product story
Edited by the Engineeringtalk editorial team Jan 13, 2003

Endevco's enhanced Model 482B rack-mounted signal conditioner is an eight-channel amplifier card that communicates with newly developed Smart Isotron (IEEE P1451.4 TEDS) accelerometers.

Endevco's enhanced Model 482B rack-mounted signal conditioner is an eight-channel amplifier card that communicates with newly developed Smart Isotron (IEEE P1451.4 TEDS) accelerometers, yet provides backwards compatibility for use with other IEPE integral electronic piezoelectric transducers and remote charge convertors.

The 482B is designed for multichannel 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 OASIS 2000 optimal architecture sensor interface system 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, 19in rack (Endevco Model 4990).

400 Series cards can be mixed or matched in any combination, giving maximum flexibility to customise 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 minimised.

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 1kHz for gains greater than 1.

The 482B also has built-in, selectable Butterworth two-pole lowpass 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 0.015Hz to 100kHz (-3dB corners).

Sensor-specific digital read/write data is in the form of the PIEEE-1451.4 Transducer Electronic Data Sheet (TEDS).

TEDS data include model number, serial number, transducer sensitivity, manufacturer, and date of last calibration.

Endevco's Model 4990 rack provides the communication link (Ethernet or RS232) between the PC and the Model 482B card.

The system controlling program is a Windows based application software providing an extremely user-friendly interface.
