Ready for WIM Reloaded?

Discover KiTraffic Digital,
the unique Weigh In Motion system for vehicle weight and tire enforcement

KiTraffic Digital, the all-new Weigh In Motion (WIM) solution from Kistler, delivers unprecedented levels of precision and usability. Driven by the new Lineas Digital sensors with their unique design, it measures axle loads and vehicle gross weight with utmost accuracy – even with lane changes.

These advantages make KiTraffic Digital the solution of choice for direct weight and tire enforcement of overloaded trucks. The fully digitized measuring chain ensures ease of integration and operation: setup and cabling are highly efficient (no loops needed), and calculations are now much easier – including compensation for various environmental influences (such as road quality).

Based on advanced system architecture which enables calibration of every single quartz in the sensor, KiTraffic Digital delivers highly accurate results – regardless of the vehicle's actual position. With measuring accuracy of up to 2% and many additional benefits, the new Weigh In Motion system from Kistler delivers the performance that operators need for comfortable control of traffic on their roads. KiTraffic Digital was designed to measure free-flow traffic with maximum reliability, and it can even detect double, underinflated or flat tires on trucks.

The highly accurate all-new Lineas Digital WIM sensor delivers uniform signals throughout the length of the sensing element.
The all-new Lineas Digital
WIM sensor

Lineas Digital is a highly accurate sensor based on 20 years of proven WIM quartz technology. Because each single quartz is digitized and calibrated, Lineas Digital delivers uniform signals throughout the length of the sensing element. The position of the force signal is used to detect single, dual and flat tires and to compensate road influences for each quartz. And Lineas Digital offers even more benefits: robust digital signal transmission, standardized cabling with Power over Ethernet (PoE), and a proprietary interface to KiTraffic Digital systems.

Technology highlights:

  • Quartz WIM sensor for ultra-high precision
  • Digital output
  • Digitization and calibration of each single quartz
  • Uniform signals over whole sensor length
This is how Lineas Digital is manufactured
Quartz crystals
Quartz crystals are at the heart of every Lineas sensor. Up to 50 disk-shaped crystals, the same size as a contact lens, are installed in one sensor. The quartz is processed on special machines at Kistler's headquarters in Switzerland.

Assembly of the sensor
Assembly of the sensor includes installing the cables and sealing the sensor to make it airtight and waterproof. As the final step, the aluminum profile is enclosed in a foam casing that dampens lateral forces.

In-depth inspection
In-depth final inspection of the sensor includes a tightness check and various function tests. Uniform sensitivity throughout the sensor’s entire length is verified with the calibration system.
