• DIGITAL SINE CONTROLLER Model: 208-A
The 208-A digital sine controller is designed to perform sine vibration tests. Its control technology uses an analog-to-digital conversion method of changing resolution and synchronous integration, therefore, it permits to finish a measurement in only one cycle (@1/50 resolution) to accomplish the required vibration control. The display part is simplified to realize the low cost controller. |
|
• DIGITAL SHOCK CONTROL SYSTEM Model: 271-B
The control system is specifically designed for FS Series Shock Test System. All the features needed for reproducing the popular haversine shock pulse and any time trace (actual field waveform) and for creating a user’s own custom pulse, not to speak of classical shock pulse most commonly used until now are implemented. The 271-C allows to easily perform acquisition and reproduction of user’s data and trimming and equalizing unnecessary data. All the test conditions and operations can be extremely readily defined on a keyboard in an interactive manner. |
