1. Equipment Introduction

The VWHUB vibrating wire hub is a new device developed by Sanlian Technology Company for measuring vibrating wire signals. It includes 16 sets of channels and a waterproof outer box. Multi channel, low power consumptionPower supply to solve the inconvenience of on-site power supply and unstable voltage. The device test results are transmitted to the mobile phone via Bluetooth, avoiding manual and human errors, making it simple, easy, and fast for engineering personnel to complete on-site measurement work.

3. Product advantages

a. The device comes with LED display, which can instantly display experimental dataThe measurement data of each instrument can be directly displayed on the LCD screen, and up to 16 vibrating wire sensors can be connected. Each wiring terminal has 5 signal contacts, including 2 vibrating wire signals, 2 temperature signals, and 1 grounding signal.

b.Easy signal network connection, using RS485 connectionVWHUB can connect signals in series to the computer for real-time display through RS485 MODBUS mode.

c. Using Bluetooth transmission can avoid manual movement errorsInstrument data can be directly transmitted to mobile phones through Bluetooth, without the need for measurement and copying work. It can also be sent to email or office for real-time report processing using mobile network, which can save data entry time and errors caused by human negligence.

d. Multi channel power supply,VWHUB can be powered by 4 No.1 batteries or directly by an external power source, with multi-channel power supply and long-lasting battery life to solve on-site power and maintenance costs or unstable voltage conditions on the construction site.

4. Product application

Suitable for installing vibrating wire sensors such as steel bar gauges, support strain gauges, water pressure gauges, displacement gauges, etc. in railway subgrades, dams, or deep excavation projects.Smart measurement, a single device can replace traditional switch boxes, measuring equipment, and recorders.The product is displayed in real-time mode through RS485 MODBUS and can be applied to on-site drainage or pile load testing.
