PRECISION 28000 Signal Conditioning System
 

28000 Signal Conditioning System

The Precision 28000 Signal Conditioning System provides all the flexibility you need to manage your test measurements.

The Precision 28000 makes it easy to manage a test with hundreds of channels and a mix of transducers. Choose bridge, charge, IEPE w/TEDS, voltage (filter/amplifier), strain, thermocouple, RTD/ potentiometer, current, frequency, or other transducers. In addition, the system is compatible with all 27000 signal conditioner modules. Customize the 28000 for high-speed transient applications, static applications, or a combination of both.

The 28000 employs a graphical user interface and a collection of algorithms to help you manage your measurements. The GUI provides control panels for configuration setup, operation and test. The 28000 can also be controlled as a server on an Ethernet network.

The built-in test hardware and software (optional) provide quick go/no-go measurements which can be run before each test, and rigorous factory acceptance tests to assure you that the 28000 meets your most stringent requirements for critical applications. It won’t be long before these tests earn a permanent place in your maintenance routine. And since they are traceable to NIST, they eliminate the need for off-site calibration.

In every phase of your tests—record keeping, installation, design, set-up, operation, maintenance and upgrading—the Precision 28000 offers ways to help you save time and money over the life of the system.

28000 Test Subsystem

The performance verification of test instruments is a critical part of insuring data integrity of any measurement system. The 28000-?-TEST test system and the 28000C-BIF1-FT provide a complete suite of tests that may be run on the instrument “in-place” without removing the system from the equipment rack. The tests check out all critical system specifications, are NIST traceable and are the same manufacturing tests that are run at the factory.

Three levels of test are provided.

• Pre-Test Verify and Diagnostics

• Factory Acceptance Tests

• Go/No-Go Tests

Pre-Test Verify and Diagnostics are used to confirm that all elements of the Test System are functional. The Factory Acceptance Test (FAT) does a complete parametric performance checkout of the 28000 System. Parameters such as Common Mode Rejection Ratio (CMRR), noise, offset, gain, frequency response, amplitude match and phase match are tested to original factory specifications. For a quick checkout of the equipment prior to a test run, the Go/No-Go test may be run to measure system performance of the current programmed setup.
