Comparison of Key Features of Weigh-In-Motion Sensors

Image
The three mainstream types of Weigh-In-Motion (WIM) sensors ： Quartz (Enviko and others), Plate Type, and Strip Strain Gauge, each have their own characteristics. Below is a comparative analysis of their features.   Quartz Piezoelectric sensors use the piezoelectric effect, offering high-frequency response, a wide measurement range, compact size, easy installation, and no power supply requirement. They work well for speeds from 1-200 km/h, have excellent long-term stability, low maintenance costs, and a lifespan of 5-10 years. Plate Type sensors use strain resistance technology and are suitable for low-speed (0-40 km/h) or static weighing. Accuracy decreases above 30 km/h. Installation requires a large foundation pit, leading to long construction times, significant traffic disruption, high maintenance costs, and a short lifespan of 1-3 years. Strip Strain Gauge sensors are designed for medium to low-speed weighing (1-60 km/h) but become less accurate above 40 km/h. Installa...
