Product outline

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.

LCD touch panel

Setting operation can be effortlessly performed by a direct touch on touch panel.

Excellent operability

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.

Saves measurement data in an SD card

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.

Plus common/ minus common shared sink type/ source type selectable

Its input type is combined-use plus common / minus common while its output type is selectable between sink type and source type. It can be connected to various types of external equipment such as PLCs.

4000 times/sec. high-speed processing

F381A is installed with a high-speed A/D converter and high-speed CPU that can process sensor signal input at 4000 times/sec with this, fluctuations in narrow values will not be overlooked.

Wide array of interfaces

F381A provides a wide array of interfaces to give flexibility in system networking. As starters, there is the Ethernet and the proven RS-232C that can provide a direct link to site PLCs such as the OMRON DeviceNet or the MITSUBISHI CC-Link without the need for any bridging devices.

Comparison & hold function by waveform display

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.

Waveform comparison function

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.

＜Front reference & back reference＞

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.

＜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.

Multi hold function

After the measuring area is divided, judgment can be carried out while type of hold (sample, peak, valley, P-P, Average, max, min, inflection point, End displacement) is interchanged at will. It is capable in specifying Hi limit value, Lo limit value and type of hold at each interval. Multiple point judgment is available through its processes such as detection of inhibit timer soon after the start of insertion and judgment of load before finishing insertion process via Inflection Point Hold.

Displacement input as a standard equipment

It performs 2-dimensional waveform comparison & multi hold through its dual input from the displacement sensor and strain gauge sensor. On X-axis, voltage or pulse input can be connected while on Y-axis, strain gauge sensor can be connected. This is highly effective for applications which are difficult to control only by time factor such as the control for pressing time of press machines and for the imposing time on works with indivisual differences.

* When nothing is connected with X axis, Waveform Comparison & Multi Hold by the time series can be done.

* The voltage input is an option.

Comparison results display

The comparison results of Waveform Comparison Function and Multi Hold Function can be verified on the display.【Result(List)】(An individual display) and 【Result(Single)】(a list display) to selection is possible.
