Enviko CET8312 Piezoelectric Quartz Dynamic Weighing Sensor

Image
1.    Summary CET8312 Piezoelectric Quartz Dynamic Weighing Sensor has the characteristics of wide measuring range, good long-term stability, good repeatability, high measurement precision and high response frequency, so it is especially suitable for dynamic weighing detection. It is a rigid, strip dynamic weighing sensor based on piezoelectric principle and patented structure. It is composed of piezoelectric quartz crystal sheet, electrode plate and special beam bearing device. Divided into 1-meter, 1.5-meter, 1.75-meter, 2-meter size specifications, can be combined into a variety of dimensions of road traffic sensors, can adapt to the dynamic weighing needs of the road surface.   2.    Picture of CET8312 3.    Technical Parameters Cross section dimensions ( 48mm+58mm ) *58 mm Sensor Length 1m / 1.5m / 1.75m / 2m Cable length From 25m to 100m ...

Improved Installation Scheme for Piezoelectric Quartz Weighing Sensors on Asphalt Pavement

Image
  1. Background Technology   Currently, WIM systems based on piezoelectric quartz weighing sensors are widely used in projects such as overload monitoring for bridges and culverts, non-site overload enforcement for highway freight vehicles, and technological overload control. However, to ensure accuracy and service life, such projects require cement concrete pavement reconstruction for the piezoelectric quartz weighing sensor installation area with the current technology level. But in some application environments, such as bridge decks or urban trunk roads with heavy traffic pressure (where the cement curing time is too long, making long-term road closures difficult), such projects are difficult to implement.   The reason piezoelectric quartz weighing sensors cannot be directly installed on flexible pavement is: As shown in Figure 1, when the wheel (especially under heavy load) travels on the flexible pavement, the road surface will have a relatively large subsidence. How...
