3E400 Axis Force Sensor

Features:

  • The 3-axis force load cell measures forces simultaneously on 3 mutually perpendicular axes: and interference between channels.
  • Each axis provides a complete bridge output and requires no mathematical manipulation.
  • The 3-axis load cell is built to minimize eccentric loading effects and interference between channels.
  • This 3-axis load cell is ideal for many industrial and scientific applications such as aerospace, robotics, automotive and medical research (orthopedics and biomechanics).

Application Areas:

  • Force application control in robotics
  • Automotive crash test
  • Industrial test benches
  • Grinding force control, etc.

LOAD CELL SELECTION IN WEIGHING SYSTEMS

How many load cells should be used

Selection of load cells to be used in a weighing system (Load Cell Selection) is according to the design of the system varies.

The ideal use should be 4 load cells in platform scales and 3 load cells in Tank and Silo weighing.

If there are 4 or more load cells in a tank weighing, only 3 or 2 load cells will carry the total weight. In this case, excessive fatigue will occur in the load cells.

Like this. In cases, the output values of each load cell can be measured and the loads on the load cells can be equalized by supporting the bottoms of the ones with low loads with thin plates.

Load Cells should be placed so that an equal amount of weight falls on each load cell.

LOAD CALCULATION

Load Cells can be used in normal and It should be selected with a capacity to carry the total and extreme loads applied in exceptional cases.
Capacity selection should be made by calculating the minimum load cell capacity as follows.

Safety Factor Q

Safety Factor, which generally depends on the environmental conditions written below, also includes

– Eccentric loading conditions

– Shocks and Dynamic loads

– Wind Forces

Weighing System Accuracy

Load Cells and Weighing System resolution and division are determined by the combination of the indicator.

Desired resolution and division can be determined according to the formula below.

EXAMPLE

Kobastar GTI with 4 Load Cells, each with a capacity of 5 tons, 2mV/V output. If we want to have 15 tons capacity and 2 Kg divisions in a weighing
system using a weighing indicator, the result will be as follows.

Since the minimum signal increase in the Kobastar GTI weighing indicator is 0.6µV/e and with the above formula
since it is lower than the calculated value of 1 µV, it means that we can easily apply 2 Kg divisions.

SUPPLY VOLTAGE

Just like the supply voltage in the weighing indicator, the current drawn by the Load Cell is also important, this tells us how many loads. Kobastar GTI indicator can operate 8 pieces of 350 ohm Load Cells.
also explains that we can connect and operate it in parallel, Kobastar GTI indicator can operate 8 Pieces of 350 ohm Load Cells.
