Quantity:

F381A is a dynamic force processor integrated with a strain gauge sensor that can display physical quantities such as pressure, load and torque in waveforms. It is able to visually capture in waveforms the fluctuations in physical quantities which are difficult to capture by only numerical values. With a 4000 times per second for high-speed processing, it is also ideal for narrow value fluctuations and comes equipped with a HI/LO limit comparison function, various hold functions and judgment function. F381A can be used in a wide-range of applications such as in control systems used in production control, automatic devices or testers.




These functions are used to judge the acceptability of measurement waveforms. Depending on type of applications, Waveform Comparison Function and Multi Hold Function can be jointly utilized for judgment.


Measurement data and set values can be logged (recorded) in the SD card. Such data can be retained as 100% recorded quality data or be used when setting up equipment or when performing cause analysis or improvement of problems. The data can be easily converted to CSV format and is therefore easily edited in Microsoft Excel or the like.



<Relative displacement>

In respect to the measurement waveform, the setup Hi/Lo limit waveforms can be set to relative displacement. When reference point is set at displacement or time, the set waveform will be in relative displacement at the load reference point of the measurement waveform.



F381A is no nonsense and straightforward and is made able to automatically mask non-required setting items and also to display a setting in the required sequence when that particular setting item has a specific setting sequence.


In respect to the measurement waveform, the setup Hi/Lo limit waveforms can be selected to be the front or back reference. With this, accurate judgment can be done even when the work inserting mold is uneven.


This function compares the actually measurement waveform against the setup Hi/Lo limit waveforms and will give out an NG judgment when any of the point exceeded the set Hi/Lo limit waveforms. As it compares the measurement waveform in overall, accurate judgment can be made even in applications that are unable to narrow down its judgment.
