Stimulus test cell accelerates sensor testing
The HA7300 stimulus test cell announced by Advantest is a full capability solution for the testing of differential pressure sensors which are becoming pervasive in modern automobile designs focused on better fuel economy and green technologies. The HA7300 delivers high-speed, highly precise test temperature control with a proprietary technology that utilises a heat or cold plate to control the temperature of the sensors under test.
The test cell also enables accurate application of two separate pressures within a short time, using a dedicated pressure controller and pressure application nozzle newly developed by Advantest.
A maximum of 8 devices can be measured simultaneously, achieving unprecedented efficiency in the testing of these high-volume devices.
The HA7300 also dramatically reduces floor space, development, and production manufacturing costs, compared to existing test environments.
These savings are achieved by utilising a single test environment from design and characterisation through to production test.
The measurements are performed by Advantest’s EVA100 system which is an integral part of this low-cost test-cell solution.
Automotive differential pressure sensors are gaining in importance due to their role in supporting green functions such as CO2 reduction and better fuel economy.
However, differential pressure sensor test presently relies on multiple temperature and pressure test units.
These outdated approaches suffer from ongoing costs associated with large floor space requirements, high complexity, poor reliability, difficult maintainability.
Advantest’s new HA7300 addresses these issues by dramatically simplifying the differential pressure test process with an integrated test cell that delivers results with increased speed, accuracy and reliability within an ultra-small, compact footprint.
The HA7300 is the successor to the HA7200, the temperature and pressure unit for in-vehicle pressure sensor test released by Advantest in 2015.
The new test cell expands Advantest’s in-vehicle sensor test coverage and also contributes to improved automobile functionality through better testing.
