The 921B Force Displacement Test Station is one of the most versatile, accurate and cost effective test stations of its kind

It features accuracy levels equal to or exceeding those of much more expensive, dedicated systems. It is ideal operating as a stand alone production line tester. The operator is presented with a pass/fail indication for the devices being tested. The Model 921B may also communicate with a PC and provide data for analysis and storage. The analysis includes numerical (tabular) results as well as graphical display of the tested parameters. This line of displacement-force switch test stations has a positional resolution of 0.0001 inches (0.0025 mm). Quality test departments will appreciate the high accuracy readings provided over the complete travel range.

Interchangeable force sensors with ranges up to 50 lb. (22.7 kg )are available. The 921B also permits the user to change the probe tip. The test station performs a calibration on the complete test fixture. This calibration removes the deflection and compression effects that can reduce reading accuracy. The calibration is performed over the range of forces specified in the specifically configured setup.

Invaluable as a test tool for qualifying first article product, audit testing, engineering investigation and life study tests, the 921B can also be used in automated production areas. When integrated with an automatic feed or an x-y positioner, the 921B functions as a cost-effective automated test station ideal for a wide variety of production applications.

The 921B is provided with a user friendly application software that runs on Microsoft Windows™ based PCs. The output data is in Microsoft Excel format that allows easy import of data for statistical process control (SPC).
