Load Monitor/N700｜KOMORI SAFETY DEVICE CO.,LTD

LoadMonitor　N700

The N700 is important for press operation and in-die applications. It is used with "in-line" load cells and strain gages. Die setup, SPC work and quality assurance are made easier when using a N700 Tonnage Monitor. Not only will it monitor force, but it will assist in protecting your investments by reducing downtime, improving productivity and improving product quality. 。

Outline

· The press forming load function will be greatly improved at 1,2 ch.
･ Stable quality control is possible with the auto zero function even with the old press machine.
· Four load setting modes that can be used according to work.
· Compatible with TT graph software It is possible to display waveform on PC.
Easy operation with easy-to-read digital display

N 701 installs one load sensor and displays only the total comprehensive load and monitors loads only by total load.
N702 installes two load sensors and displays the total load, the right load, the left load which are switched with the snap switch.
The upper and lower limit loads for detecting defects can be easily set by simply turning the knob.
With automatic zero balance function that can respond to sensor temperature change and wide gain (sensitivity) adjustment function,N702 display load signal stably from small distortion to large distortion.
The measurement mode is commonly used in basic peak mode.
Because it is a compact housing, it can also be embedded inside the control panel.

selectable 4 operation mode

The N700 supports four diﬀ erent means of setting high and low load set points:
1．Manual mode
Manual set point adjustment mode monitor voluntary Load value.(manual setting to higset point and Low set point).

2．Repeatability mode
the set points are re-calculated each cycle based on a percentage above and below the last load value.(It can be used to monitor variations in bottom dead center accuracy of high speed press.)

3．Benchmark +/- percentage of capacity (Auto set capasity mode)

The set points are recalculated by adding or subtracting a percentage of the machine capacity to/from the benchmark value when the benchmark is established.

4．Benchmark +/- percentage of benchmark( Auto set target mode)

The set points are recalculated by adding or subtracting a percentage of the benchmark to/from the benchmark when the benchmark is established.

Specification

SENSOR INPUTS	Accepts one or two 350 ohm full-bridge strain gage sensor(s).
SENSOR EXCITATION	+5VDC and-5VDC(10V) at70mA maximum. Short and open circuit protected.
ANALOG SIGNAL OUTPUT	3.5mm stereo phone jack. 0-2.5VDC=Maximum capacity of display.
SENSITIVITY	0.057mV/V to 0.625mV/V for (X10) high gain range at capacity. 0.568mV/V to 5.00mV/V for (X1) low gain rangeat capacity.
