Compact DIN 96 x 48 mm Size Digital Indicator
F331 is a digital indicator for strain gauge sensors to measure load, torque, pressure and displacement. Compact and simple configuration, practical machine with features such as hold and judgment.
Upper and lower limit comparison and judgment result output Output (2 points) : Selectable from OK・NG・HH・HI・LO・LL
Hold function with the speed of A/D converting 300 times/sec. (Sample・Peak・Bottom・P-P)
Wealth of interface
USB as a standard feature. BCD output, D/A converter(Current output), RS-485(Select from Modbus-RTU and original format), RS-232C are available as an option.
Special PC application software
We prepared the special software that can easily set up F331, downloading of measured values and analyzing on a PC.
Setting and controlling can be done by a PC for installation and when you got NG judgement result.
You can do initial setting and calibration. Installation task is easy because you can do it with confirming waveform data. PC is not required after operation is started.
Initial setting and calibrations
You can do the read・write of the setting values and calibration.
Check by waveform
It displays input signal in waveform.
You can see output timing of upper/lower limit comparison and hold at a glance. Saving of waveform data is also possible.
■When continuous control is required for e.g. long term test
When it is required, you can read and record measured value in real time by connecting a PC all the time.
It records measured value and status(Upper/Lower limit, Hold) for up to 10000 times. You can check judgment result by the OK/NG counting function.
■If result is judged as NG（Not good）
You can pursue the cause by comparing parameter set and waveform data of NG result with the data of when it is installed.
Suitable for production line quality control such as pressure load of press or swage machine, pass or fail judgment of the automated machines and testing machines.
