Product Description

The CRMR series rail flatness measurement instrument, also known as the "electronic straightedge," can precisely measure the rail head and the short-wavelength undulation on the rail sides and top. It supports one-time measurements up to 10 meters in length, with a detectable wavelength range of up to 3 meters.
Based on a patented multi-point string vibration detection technology, it overcomes the traditional limitation of single 1-meter measurements by conventional rail straightedges, significantly improving measurement efficiency.

Technical Features
• Exclusively based on a patented Chinese invention for single-string multi-point detection, independently developed to surpass all imported electronic straightedge technologies.
• Supports a wide range of wavelengths up to 7000 mm, featuring high measurement accuracy, strong stability, and excellent vibration resistance.
• Device net weight is 2.5 kg; single measurement can reach up to 10 m with a repeatability of 0.01 mm.
• Simultaneous measurement of the rail head and rail side flatness improves measurement efficiency.
• Used for measuring rail flatness, evaluating weld condition, and verifying maintenance effectiveness.
• Utilizes Class 00 granite calibration platforms to verify sensor accuracy and ensure reliable measurement calibration.
• Non-contact measurement enables detection of short-wavelength rail geometry through weld joints.

Data Acquisition Software

The CRMR series rail flatness measuring instrument uses a mobile phone app as the upper-level controller and communicates via Wi-Fi.
The measurement waveform data supports multiple on-site measurements with overlay display, allowing comparison of repeatability and before-and-after grinding waveforms, thereby assisting in rail grinding operations.

Measurement Input Information

• The measurement app can integrate evaluation and analysis functions according to customer requirements, with results synchronized to the server.
• Measurement results include rail flatness and track position information.

Measurement Data

• The measurement app can integrate evaluation and analysis functions according to customer requirements, with results synchronized to the server.A 4-meter Class 00 granite calibration platform is used as the reference. It achieves a repeatability of 0.01 mm within a 3-meter range.

Result Comparison

• Compares the rail head and side waveforms with the results from a 1-meter standard straightedge.
