Description

Introduction:

JMZX-50xxAT Earth Pressure Cell ( VW & Smart Type) is a vibrating wire sensor for measuring earth pressure, suitable for soil internal stress measurement under various conditions, and applied to roadbed, slide-resistant pile, retaining wall, tunnel and other engineering earth pressure measurement in highways, railways, embankments, mines and other industries. Long-term monitoring and automated measurements are possible. Its installation mode is various, usually use the mode that roadbed, pile waiting for test structure is formed in advance and is buried; It can also be applied to the foundation and other earth pressure measurement in the fields of construction, railway, transportation, hydropower, dam, tunnel and other engineering fields, so as to fully understand the pressure state of the measured point.

Product Features:

1. It is designed and manufactured by vibrating wire theory, which has the advantages of high sensitivity, high precision and high stability, and is suitable for long-term observation.

2.Using all-digital detection, the signal is transmitted over a long distance without distortion, and the anti-interference ability is strong

3.Equipped with intelligent memory function, the sensor stores its model number, serial number, and calibration coefficients at the factory, and can save up to 800 sets of your required measurement parameters, such as measurement time, point temperature (for temperature type), pressure value, zero-point parameters, and temperature correction values. This feature is unique to our company's products. For projects with a large number of sensors installed, this function prevents sensors from being rendered ynysable by cut test wire ends or confused test wire numbering, ensuring the long-term smooth progress of project monitoring.

4.Good insulation performance, waterproof and durable.

5.Users can choose the corresponding type of earth pressure cell according to different requirements.

6.The pulse excitation method is used for excitation, enabling fast testing speed.

7.Equipped with our company's comprehensive readout, it can directly display the pressure value as well as the vibrating wire frequency, making the measurement intuitive, simple, and fast.

8.When connected to our company's manual junction box, centralized measurement can be achieved.

9.When connected to our company's automated acquisition system, unattended automatic monitoring can be realized.

10.It can directly measure the temperature at the monitoring point and perform temperature compensation (for temperature type).

Applications

The Intelligent VW Rebar Strain Gauge is used to measure the strain of rebar in the concrete structure.
