Product outline
F388A is a wave form checker integrated with a voltage / current output type 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. F388A 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.
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
F388A 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
F388A 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.
Multi hold function
After the measuring area is divided, judgment can be carried out while type of hold (sample, peak, Bottom, P-P, max, min, inflection point) is interchanged at will. It is capable in specifying Hi limit value, Lo limit value and type of hold at each interval.
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. (Latest 40 data)
