Great quality rail strain gauge scales VRT-04 model 4 weight and balance measure, from manufacturer, railroad sensors for sale
Model 4 rail strain gauge scales. The scales are made of the customer's existing operating rails without construction work, cutting, drilling or other mechanical intervention. A set of strain gauges is attached to the existing rails to measure the deformation of the rail under the pressure of the wheels. Based on the measurements, the program calculates the wagon weight and loading symmetry. The sensors are mounted between the crossties without interfering with the track structure and stopping traffic.
The system is equipped with two 2-4 MP varifocal IP-cameras. Pictures of cars are taken at the moment of passing the scales and stored in a local folder on HDD and available for viewing from the weighing software. The cameras are mounted 5-7 meters away from the rail and at a height of 3-4 meters from the rail level.
Type:
Model 4 rail scales for weighing in motion consist of four measuring lines (load receptors), each LR includes two independent wheel load measurement units (WLMU) connected to each other, and two cameras for car sides photofixation. The LRs create four independent data sources and in case of failure of one LR, the remaining LRs will keep on working.
Measurement and inaccuracy:
Error within 1% when weighing at 1 to 10 km/h, within 2% when weighing at 10 to 20 km/h, within 5% when weighing at 20 to 60 km/h, transit speed is not limited.
Error and speed may vary depending on the particular track section.
Car numbers recognition system:
The cars are photographed by IP cameras mounted on both sides of the car and take a photo of the tail number on each side. The cars are photographed by IP-cameras mounted on both sides of the car. Photos of the car with numbers are transmitted by the weighing software to the neural network based machine vision controller for autonomous car number recognition. After that the photos are processed by the machine vision controller, and the result returns the character values of the number to the weighting software. The authenticity of the car number is determined by preset recognition threshold and the checksum. Additional equipment of the car numbers recognition system is installed close to the weighing computer. The system guarantees recognition accuracy up to 95% when using one type of cars. Recognition is made at speeds up to 10 km/h. It may be necessary to use spotlights for better operation. Spotlights are purchased and installed by the buyer, depending on the conditions and the speed. The best photo quality is achieved at speeds up to 7 km/h.

STATERA
VRT-04 scales are a patented innovation of engineers from Rostov-on-Don, Russia.
We produce scales out of your rails without construction work, cutting, drilling or other mechanical intervention.
A set of strain gauges is attached to the existing rails to measure the deformation of the rail under the pressure of the wheels. Based on the measurements, our program calculates the car weight and loading symmetry.
The sensors are installed between sleepers with no intervention with the track structure and stoppage of train traffic. Weight is measured in motion at a speed of 1-90km/h.
How long does it take to install the scales?
The installation time of the scales, depending on the configuration, takes from 6 to 12 hours
Do I need to close the movement of trains during the installation of scales?
It is not necessary to close the movement of trains during the installation of scales.
On what type of rail and track width can the scales be installed?
The scales can be mounted on any rail and track width.
What kind of foundation is needed for the scales?
The foundation for the scales is not needed
How long should a piece of rail be cut?
The scales are installed on an existing rail and do not require cutting out the rail. We make scales from an existing rail.
At what temperature can the installation of the scales be carried out?
The air temperature for the installation of the system should be from -20 C to +40 C
