Product outline
F372A is a digital indicator integrated with a strain gauge sensor that can display physical quantities such as pressure, load and torque in waveforms.
- 2000 times/sec. high-speed processing
- Work no. can set up up to 16 types
- Can start measurement even there is no external signal
- Analog monitor output
- Variety of interfaces
- 3.5 inch color LCD module & touch panel
- Multi calibration function
- Alarm function
- Can confirm forcs pattern before measurement start. (Pre Trigger)
Voltage output is proportionate to the input signal making the recording on recorder convenient.
Approx. 2 V per 1 mV/V strain gauge input
RS-232C/ CC-Link/ DeviceNet/ D/A output/ BCD output (Sink type/ Source type)
Setting operation made easy via direct touch on the touch panel.
Stores calibration values for 4 ch portions and can be selected via touch panel or external signal
Monitors if the measured value is abnormal
– Hi/Lo limit for in comparison setting
– A/D input range
– Overflow
– Digital zero regulation value
Waveform display
Input signal from the sensor is displayed as real-time waveformdisplay.
Greatly shortens the adjustment time during the machine’s start-up.
Assuredly cancels vibration, noise and unwanted inputs.
The filtering results can be confirmed from the waveform.
Greatly improves the machine’s reliability through its in-process operational check.
The machine’s operation can be consistently monitored through the waveform and hold points in-process check.
Can also be used when investigating causes of the machine’s trouble.
Work selection (multi hold)
Necessary points in waveform are taken out to make HI/LO limit comparisons.
Operating work*is selected to perform comparison and judgment under various condition settings.
* 16 types of settings per operation (types of hold, HI/LO limit set values) can be stored.
■ Hold types
Sample, Peak, Bottom, P-P, Average, Inflection Point, Relative Maximum, Relative Minimum, Relative Difference
■ Setting of range
– Externally specified range (Peak, Bottom, P-P, Average)
– Externally + Time specified range (Peak, Bottom, P-P, Average)
– Level + Time specified range (Peak, Bottom, P-P, Average)
– Level (Peak, Bottom)
＜Double Hold＞
Specifically combined two types of hold functions are performed simultaneously in one detection. Hold modes can be selected from 26 modes shown below.
HI/LO limit comparisons of the difference value between the presently measured hold value and the previously measured hold value can be made.
Difference value = Present hold value (indicated value) – Previous hold value
＜Relative Value Comparison＞
HI/LO limit comparisons of the difference (relative value) between hold value A and hold value B can be made.
