VW Type Load Cell
Model: SJ-85 / SJ-100

│ DESCRIPTION │

VW Load Cell is to measure the reaction force available at Earth Anchor to analyze in connection with the change of the retaining wall and judgment of the stability of the support after construction of anchor. Also, it is to measure the axial force affecting the strut.

│ APPLICATION │

• To measure the reaction force available at Earth Anchor
• To measure axial force affecting the strut
• To ensure the stability of the support system such as retaining wall and tie back, etc.

│ FEATURE │

• Excellent reproducibility and responsiveness which is free from cable length or resistance change
• Perfect waterproof structure
• High stability and high sensibility
• High accuracy even for the eccentric load
• High accurate resistance temp sensor mounted.
• Two types separated considering the load pattern

│ CHARACTERISTIC │

For VW Load Cell, the VW stainless gauge was mounted by trisection (quadrisection) equally in the cylindrical cell hole precisely processed for the heat treated alloy materials. The principle is that when the cell is affected by the load the tensile force of the VW gauge mounted will be changed.

When the VW Load Cell is magnetized by the magnetic coil mounted due to the load the vibration wire will generate the resonant frequency and this frequency will be transmitted to the output device to display the necessary engineering unit. It can be calculated as the load unit accurately and easily by the conversion coefficient provided.

The reliability of the VW Load Cell is guaranteed since it is calibrated for each product through the verification of the effectiveness of the certified load tester. To get the best result, the load cell should be installed between upper and lower bearing plate and he Earth Anchor should be located in the center of the cell.

The bearing plate will prevent it from bending or absorbing compression power to help affect the distribution load on the entire load cell. The housing and signal cables are completely waterproof and humid-resistant to get the data on a stable basis for long time, so that it can be used under the extreme conditions at civil work while protecting from external shock, etc.

Linear Value (KHz2)
- Application: It can be used for load cell and VW pressure meter. It is also mainly used when the frequency value is decreased according to the increase in the engineering unit which is the reference standard for calibration.
- Unit: 103Hz2
- Unit Conversion
a) Hz is converted into 103Hz2 : 103Hz2 = Hz × Hz / 1000
b) 103Hz2 is converted into Hz : Hz = √(103Hz2 × 1000)
