Keithley Instruments Inc. has announced the availability of its Model 2790-A SourceMeter Airbag Inflator dc electrical test system, which it claims is the only standard, commercially available test system that combines all the sourcing, measurement, and signal routing capabilities required for insulation resistance and conductor (bridgewire) continuity testing in one compact, cost-effective package.

The Model 2790-A expands the high resistance measurement capabilities of these systems to cover a span of 1 megohm to 10 gigaohms, which allows testing a wider range of airbag system characteristics in a single box.

Designed for the testing requirements of the main passenger and driver airbag inflators and modules, the product can also be used for both single- and multi-stage inflators and modules. It consists of a precision multi-function/multi-channel datalogger mainframe, plus a set of specially designed plug-in modules. These modules enable high voltage insulation resistance testing, and low current, low resistance measurements. The source/measure modules also contain tailored switching capabilities to allow automatic configuration of single- and multi-stage inflator interconnections for all needed measurements. The combined signal switching, source, and measurement capabilities of the Model 2790-A enhance test throughput by buffering test sequences in the programmable memory pattern mode, and by allowing parallel high voltage soaks on multiple single-stage inflators or individual multi-stage devices. The multiple module mainframe expandability also accommodates multi-head test stands that increase operator efficiency and minimize idle time.

The device is priced at $5,495 for a single unit purchase quantity.
