Optielectric instruments

Scientific and production company RIFTEK specialises in the development and fabrication of optoelectronic instruments for measuring geometrical quantities. We offer integrated solutions for control and automation problems – from sensing devices to multifunctional rail and wheel measuring and control systems. The basic product line includes:

Laser triangulation position sensors

  • 2D and 3D laser scanners
  • Optical sensors
  • Absolute linear encoders
  • Data acquisition, processing and indication systems
  • Devices for control of movement, distance, size and shape of objects
  • Speed and distance sensors

One of our areas of expertise is the railway sector, including wheel and rail wear measuring systems.

Wheel diameter measuring gauge

Electronic gauge is designed for measuring wheel rolling circle diameter.

Measurements are made directly on rolling stock without wheel set roll-out. The measurement of the diameter is performed according to the ‘three points’ technique, without the complete wheel coverage.

The IDK gauge contains numeric display to show the value of the wheel diameter. IDK-BT gauge additionally contains Bluetooth interface for transfer results into wheel-set wear database management system.

Railway wheel profile gauge

The laser wheel profilometer is employed for measuring geometrical parameters of the wheel flange (thickness, slope and height) and tire thickness, taking a full profile of the wheel roll surface.

Triangulation Laser Module placed inside the profilometer casing performs linear scanning of the wheel surface. Measurement results (geometric parameters and profile of the surface) are displayed on PDA, can be saved in the PDA memory, and transferred to the PC database.

The device is supplied with database and software package for wheel sets wear data storage and processing.

Back-to-back distance measuring gauge

Laser gauge is designed for measuring back-to-back distance of railway, metro and tram wheels in the course of checkup, examination, repair and formation of wheel sets. Measurements are made directly on rolling stock without wheel set roll-out.

Disk brakes profile gauge

PDA based handheld instrument is employed for laser scanning and measurement of brake disks wear parameters. The device is supplied with database and software package for disks wear data storage and processing.

Rail profile measurement gauge

Portable laser rail profilometer (PRP) is designed for non-contact registration of cross-section of the railhead acting face.

The main functions of PRP are:

  • Obtaining the information on the cross-section profile of the working railhead surface
  • Full profile scanning and analyze of the railhead acting face
  • Visualisation of the combined graphical images of actual and new cross-section

Automated wheel measuring systems for geometric parameters

We can supply automated measurement systems for geometric parameters of wheel sets, sets and wheel centres.

The system for automatic measurement of 27 geometric parameters of wheel pairs of wagons can be used in the course of incoming and outgoing inspections carried out in railcar / wheel shops, wagon depots, and wheel pair repair and gathering workshops.

Laser systems for power rail position dynamic control

The system is intended for contactless control of displacement dynamics of power rail.

Operation principle is based on the control of power rail position by triangulation sensors, placed under the rail.

Measurement Sensors

RIFTEK's measurement sensors for the railway industry includes a wide range of laser sensors and scanners.
