Weigh In Motion solutions

The secret of our WIM solutions’ outstanding performance: Kistler’s unique piezoelectric quartz technology combined with advanced sensor design. Up to 50 disk-shaped quartz crystals, each no larger than a contact lens, are at the heart of every Lineas sensor. 

Lineas sensors have proven their durability in different pavements on all continents. They work with same precision in the cold winters of Europe as in the hot desserts of the Middle East.

With their wide measuring range, Lineas sensors can accurately measure both light and heavy vehicles, maintaining high levels of accuracy across all vehicle types. From walking pace to racing speeds, our WIM solutions ensure consistent results at all vehicle velocities.

Lineas sensors are designed for long-term reliability, with a life expectancy of at least 10 years. Built on Kistler’s pioneering expertise, they are virtually maintenance-free even with extensive use, often outlasting the roads they are installed on.

As a leading provider of quartz piezoelectric measurement technology, we achieve maximum performance by using advanced production equipment operated by skilled specialists at our Swiss plant. Advanced manufacturing processes allow us to maintain full control over every step, ensuring the highest quality at every stage.

Each sensor undergoes rigorous inspections, including tightness checks and functional tests. We verify uniform sensitivity across the entire sensor length using our calibration system. Every sensor is 100% tested, factory-calibrated, and checked with high-precision tools before leaving our Swiss headquarters, ensuring reliable, top-quality products.

Our WIM solutions can be easily extended with additional third-party components such as RFID transmitters, dimension scanners or ANPR cameras for number plate recognition. We offer comprehensive solutions covering the entire measuring chain, from sensors to software. Our WIM measuring chains can be easily networked and integrated into existing ITS systems, such as enforcement solutions. 

Thanks to Kistler’s global sales and service network, we are always close to our customers. We offer a portfolio of customized services to maximize the performance of every WIM site. Customers can choose from a range of options to enhance their individual WIM user experience and prolong their system’s lifetime.

Lineas sensors are designed for quick installation, typically completed within a single day, and deliver reliable measurements for years. Lineas sensors can be installed on all types of pavement, including concrete and asphalt, with minimal disruption to traffic flow and limited need for road closures. Installation is cost-effective, requiring no heavy machinery and causing minimal road damage—only a small slot in the pavement. The modular and flexible design allows for easy adaptation to different lane widths, and the absence of screws or frames reduces the risk of flying parts, ensuring a safe and efficient setup.
