Piezoelectric Dynamic Quartz Weighing Sensor

Product Description:

The Weigh In Motion (WIM) Sensors are advanced devices designed to accurately measure the weight of vehicles as they move over a sensor embedded in the roadway. Utilizing cutting-edge quartz sensors technology, these weighing sensors employ the quartz piezoelectric effect to deliver highly reliable and precise weight measurements in real time. This makes them an essential tool in traffic management, toll collection, vehicle classification, and infrastructure protection.

One of the key features of the Weigh In Motion Sensors is their impressive output voltage range of DC-5V to +5V. This wide voltage output capability ensures compatibility with a variety of data acquisition systems and signal processing equipment, allowing seamless integration into existing traffic monitoring and control infrastructures. The stable and consistent voltage output is a direct result of the quartz sensors' inherent properties, which maintain accuracy and reliability even under varying environmental conditions.

These WIM sensors are engineered to handle a single axle load of up to 40 tons, making them suitable for a broad spectrum of vehicles, from light passenger cars to heavy-duty trucks and freight carriers. This capability ensures that the sensors can be deployed on highways, bridges, and toll stations to monitor heavy traffic loads, helping to prevent overloading and potential damage to road infrastructure.

The total weigh accuracy of the sensors is guaranteed to be at least 95%, which is a significant benchmark in the weigh-in-motion industry. This high degree of accuracy is achieved through the precise piezoelectric effect of the quartz sensors, which converts mechanical stress from the vehicle's weight into an electric signal with minimal error. The reliability of this accuracy level enables authorities and operators to make informed decisions regarding vehicle compliance, safety regulations, and road maintenance scheduling.

Designed to accommodate traffic flow efficiently, the Weigh In Motion Sensors support up to 8 lanes simultaneously. This multi-lane capability allows for broad coverage on busy highways and expressways, ensuring that multiple vehicles can be weighed concurrently without disrupting traffic. The ability to monitor several lanes at once enhances operational efficiency and reduces the need for multiple installations, lowering overall infrastructure costs.

The sensors operate within a frequency range of 0.01 to 10 KHz, providing flexibility in signal processing and data analysis. This frequency range allows the sensors to capture dynamic load variations as vehicles pass over the sensor, ensuring accurate weight measurements even at high speeds. The quartz piezoelectric effect is particularly effective in this frequency band, enabling the weighing sensor to respond quickly and precisely to changes in load.

At the heart of the Weigh In Motion Sensors lies the quartz piezoelectric effect, a natural property of quartz crystals that generates an electric charge in response to mechanical stress. This fundamental principle allows the quartz sensors to function as highly sensitive weighing sensors, converting the pressure exerted by vehicle axles into measurable electrical signals. The durability and stability of quartz crystals contribute to the longevity and consistent performance of the sensors, making them a reliable choice for long-term deployment in various traffic environments.

In summary, the Weigh In Motion Sensors combine sophisticated quartz sensor technology with robust engineering to deliver a high-performance weighing solution. With an output voltage range of DC-5V to +5V, the capacity to measure single axle loads up to 40 tons, a total weigh accuracy of at least 95%, support for up to 8 lanes, and a frequency range of 0.01 to 10 KHz, these sensors are designed to meet the demanding needs of modern traffic management systems. Their reliance on the quartz piezoelectric effect ensures precision, durability, and reliability, making them an indispensable component in the field of dynamic vehicle weighing and road safety monitoring.
