Product Description

Based in Guntur, Andhra Pradesh, we are becoming as one of the reliable manufacturers of Medium Speed WIM. It is the most innovative system required to measure the weight of vehicles moving on highways. This system is installed on the highway roads and as vehicle passes through, it records the weight. It works on the principle of using load transfer torque tubes that transfers the weight of trucks or cars on the load cells. Medium Speed WIM can be used for HTMS projects, traffic data collection, and toll ETC lanes as well.

Features:

 

  • High weighing accuracy

  • Easy to install with low maintenance

  • Sturdy structure

 

 

Medium Speed WIM

Indicator

The MVR Weight Indicator for In-Motion Vehicle Scale offers the ideal combination of accuracy and speed.

  • GLCD display with four keys on the front panel of eldon MS box.
  • Serial strings for communication as per your requirement.
  • Logic with two loops and one IRS (pnp) type.
  • MVR will supply two parallel sensing Light curtains with each controller.
  • The Light curtains will installed in a box near WIM along with junction box by MVR
  • A power supply of 24V to drive IRS.
  • LEDs on mother board for loop sensors and IRS.
  • This is low speed (max speed 20 kmph) system with accuracy of 2-4% of fsc and depends on the level of section before and after weighing zone.

Key Benefits

  • High vehicle throughput
  • Maximize operational Productivity and cost savings

  • A power supply of 24V to drive IRS.
  • LEDs on mother board for loop sensors and IRS.
  • This is Medium Speed WIM (max speed 50 kmph) system with accuracy of 2-4% of fsc and depends on the level of section before and after weighing zone.

Load Cells
MVR LC’S are double ended shear beam load cell ideally suited for Truck, track, onboard weighing applications. Its construction of high alloy tool steel provides optimum protection under impact loading & adverse conditions. The cell is environmentally protected with waterproof seal and is Electro less nickel plated to assure resistance against corrosion.
