| Description |
Model 1370 VW Soft Inclusion Stress Cell is sensor for automatic measurement. It can be installed at the large borehole of HQ, PQ, and 6 inch.
VW Soft Inclusion Stress Cell consists of round shape sensing part, wedge sensing the stress, and bearing plate for taking load. It can be installed in the precisely bored holes by using manual setting tools.
In the VW sensor structured in the form of center hole, wedge sensing the scale of the impacted force transmits it to the sensor, and magnetic coil and vibrating wire are built-in.
If there is any change in tension of vibrating wire caused by the changed scale of load, it shall be magnetized by the magnetic coil and generates the resonant frequency to be transmitted to the readout unit and recorded in the form of the necessary engineering unit.
The VW Soft Inclusion Stress Cell is designed for waterproof, and a temperature device for compensating for temperature variations in the transducers.
