Weigh-In-Motion Truck Scales for Enforcement Screening
Screening for Enforcement in the United States
Weight Enforcement is vital to minimize the damage caused by overloaded vehicles to roads and highways, and to increase safety for the operators. Detection and identification of these vehicles is done at low (LS-WIM) and high-speeds (HS-WIM.)  WIM is an efficient and effective method for screening and pre-selection of vehicles for static weigh stations, and direct enforcement of weight violations where legislation incorporates Weigh-In-Motion capabilities.

Typical Configurations

Strip Sensors 4 inline Strip Sensors 6 inline












Strip sensors for screening, pre-selection, and direct enforcement incorporate strain gauge sensor technology:
  • WIM site installation employs four to six sensors, loop, and electronics
  • Consistent Accuracy for Selection of Vehicles from Screening
  • Improve Vehicle & Operator Safety
  • Simple Integration of Sensors into Existing Enforcement Systems
  • Stable readings with environmental fluctuations of temperature
  • Minimally invasive in-ground installation
  • Does not require frames or drainage
  • Maintenance free operation
 
Regions can have different requirements for accuracy of systems employed in enforcement WIM applications.  ASTM E1318, COST 323 A(5) and COST 323 B+(7) are standards commonly referenced for these sites.  Four (two pair) or six sensor (three pairs) installations have been used in countries for these applications.  Intercomp strip sensors have undergone OIML R134 performance certification testing.
 
Strip sensors are also used in data collection, tolling (ETC), ports of entry or departure, and bridge and pavement protection.

LS-WIM Axle Scale
Typical Configuration
LSWIM INSTALL
LS-WIM Axle Scales use strain gauge technology for low speed enforcement:
  • WIM site installation employs single axle scale, loop, and electronics
  • High degree of accuracy at low speeds
  • Stable readings with environmental fluctuations of temperature
  • Small Scale Footprint vs. Static Scales
  • Durable Platform Construction
  • Simplified Maintenance
At low speed, these scales can meet requirements for accuracy of systems employed in enforcement WIM applications.  The Intercomp LS-WIM Axle Scale has undergone OIML R134 performance certification testing.
