Ultrasonic measurement Accurate Thickness Control for Highway Maintenance with Averaging Leveling Beam
Working principle of single probe ultrasonic balance beam
The single probe ultrasonic balance beam emits ultrasonic signals to the ground through a single ultrasonic probe and receives the reflected signals. Calculate the distance between the probe and the ground based on the round-trip time of the signal and the propagation speed of ultrasound in the air.
Application scenarios:
1.Urban road construction
Ensure the smoothness of urban roads and improve the comfort of citizens' travel.
2.Highway maintenance and renovation
Accurately control the paving thickness of the maintenance area to ensure a smooth connection between the repaired road surface and the original road surface.
Functions and Features:
1. The Chinese and English working interface of the controller can be switched, with intuitive image and convenient operation;
2. The controller has a parameter setting interface, which is convenient and simple to adjust the parameters, and can give full play to the excellent performance of the paver, making the construction intelligent and reliable.
3. The controller has short-circuit protection and automatic sensor recognition function.
4. The single-probe ultrasonic sensor collects measurement data multiple times, and the design of the compensation rod can eliminate the shortcomings of ultrasonic measurement, and the measurement is accurate.
5. Simple design, convenient and flexible operation, affordable price. Based on CAN bus design, it can always be used in conjunction with instruments based on CAN bus design.
