We also offer a ruggedized Symbol MC70 PDA with industrial specifications
and GPRS. MC35 with built-in GPS

 RAILPROF is controlled by a Pocket PC (PDA). Vertical and lateral geometry are measured simultaneously. The measuring results are automatically sent to the PDA, which carries out all the calculations like filtering and computing the first derivative of the vertical geometry. This is in accordance with the new force-based weld standards of ProRail, the Dutch Rail Infra Manager. RAILPROF is a tool for accurately measuring longitudinal rail geometry. Low weight (6 kg for RAILPROF 1000) and robustness could be realized through the use of high tech materials developed in space technology. Background information on new rail geometry standards

| Recently weld registration software has been developed by which also RAILPROF measurement files can be transferred wirelessly via GPRS. For details click here. | ||||

Some PDA screen shots Templates can be created for each measuring job via the 'Setup' menu. The values of the active template are used when the measuring process is started. After tapping the command measure the values of the template are shown and can be altered. If the weld is measured again or a new weld is measured the previous values are kept. |

Applications:
Checking
and acceptance of flash butt welds, thermit welds and glued insulated joints;
Positioning
of rails before welding;
Production of glued insulated joints;
Assessment
of corrugations;
Monitoring
progress of grinding process;
Acceptance
of grinding work;
Acceptance of rails for longitudinal geometry, including
straightness of rail ends.
Special Windows based desktop software is provided to download the measurement data into a PC for viewing, editing and printing.

The desktop software now offers the possibility to select records on the basis of the quality index QI. Via the find icon a screen is opened in which a choice can be made for QI Top, QI Hor, or both. The selection value is default 1.00, but the user can assign any other value. After OK the screen at the bottom left shows just the selected records, which can be moved now.

Main characteristics of the RAILPROF
1) Low weight: about 6 kg.
2) Short length: 116 cm.
3) PDA controlled measurements, wireless communication via Bluetooth.
4) Measuring length: 1,000 mm in accordance with the CEN standards; sampling interval 5 mm.
5) Measuring time: about 10 sec.
6) Data transfer to PDA and analysis: about 6 sec.
7) Data storage: unlimited on PDA internal memory or Secure Digital (SD)card.
8)
Data transfer to desktop PC via
Active Sync, memory card, or network.
With WeldRegister software wireless data transfer to central server via
GPRS.
9)
Presentation of measurements on
desktop PC via Windows menu;
easy to generate reports in for instance pdf
format.
10) High accuracy at ambient temperatures between -10 ºC and + 40 ºC:
- up to 0.5 mm: 0.03 mm
- beyond 0.5 mm: 5%.
The results are not influenced by moisture, rust, dirt or magnetic fields due to the eddy current principle; the real metal surface is measured.
11) Bottom of RAILPROF is resistant to temperatures up to 150 ºC.
12) Warranty: 12 months.
