Portable Rail Profilometer. PRP Series

Portable Rail Profilometer. PRP Series Safety precautions and measurement conditions · Prior to mounting the profilometer onto the rail, areas of contact and laser scanning of the rail surface should be thoroughly cleaned from dirt. · When mounting the module on the rail, do not allow heavy shocks of its support against the rail. · The output windows of the laser sensor must be carefully inspected and cleaned. · Do not use laser module in locations close to powerful light sources. The profilometer has been developed for use in industry and meets the requirements of the following Directives: ·...

Portable Rail Profilometer. PRP Series Operating principle Operator mounts the laser scanning module onto the railhead to be measured. Having received a command from PDA or PC, the laser module performs non-contact scanning of rail 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. Simultaneously, additional parameters can be saved: date, operator number, permanent way division, track number, rail type, etc. Rail parameters under control L-parameters Geometric parameters of the...

Portable Rail Profilometer. PRP Series Default value Used for calculation of lateral railhead wear Used for calculation of railhead width Geometric parameters of the rail under control The parameters under control and respective calculation methods are given in Table 2. Table 2. Parameter Designation Calculation method Railhead vertical Hv is calculated as a difference between the measured value and wear nominal value of new rail in direction of rail axis of symmetry Lateral railhead wear Hh is measured at the height of L1 = 13 mm from the rolling surface of rail head Lateral railhead wear Hh45...

Portable Rail Profilometer. PRP Series · After the laser module is switched on, some time will pass until automatic wireless communication is set between the profilometer and the PDA, which is accompanied by blinking of a blue LED on the laser module. The LED goes out when the link is established. · The main window of the program is updated: 10 The Measurement button, indicator of Bluetooth connection, laser module serial number and charging degree are active. There are two types of measurements: 1. Measurements without saving the results to database. 2. Measurements with saving results to database....

Portable Rail Profilometer. PRP Series · To look at the rail profile, press the Profile button , and the PDA will display the scanned rail profile as well as measured parameters: PDA program setting The Device window: Measure type Measurements with / without saving results to database Date/time setting Device type Device selection Language selection

Portable Rail Profilometer. PRP Series Measurement type Two measurement types are available: 1. Rapid measurements without saving the results. 2. Measurements with saving results to database. To set the measurement type, press the Measure type button. Then select the measurement type: Rapid measurement or Measurement with saving. Press the Save button. All parameters as well as measurement results can be presented in the Metric system (millimeters), or in the English system of units (inches). To set the units of measurement, press the Units button. Then select Millimeters (mm) or Inches (in),...
