F372A is a digital indicator 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 maximum 2000 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.
F372A is the best digital indicator for graders and testers used in results judgment of assembling work and auto machining.
F372A is digital indicator for strain gauge type sensors to measure pressure, load, torque. With various hold functions, they contribute to production line quality control.
Extensive comparison functions
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, Valley, P-P, Average, Inflection Point, Relative Maximum, Relative Minimum, Relative Difference
■ Section setting
– External section (Peak, Valley, P-P, Average)
– External + Time specified section (Peak, Valley, P-P, Average)
– Level + Time specified section (Peak, Valley, P-P, Average)
– Level (Peak, Valley)
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.
