Product Description

The CRM series rail corrugation measurement instrument can precisely detect short-wavelength undulations on both the left and right rails. Within a wavelength range of up to 3 meters, it provides segmented data such as RMS values, peak-to-peak amplitudes, and short-wavelength roughness spectra of the rail.

Technical Features
• Independently developed based on China's patented multi-point N-string vibration detection technology, surpassing all imported corrugation measurement technical solutions.
• Wide detectable wavelength range up to 3000 mm, with high measurement accuracy, good stability, and strong anti-vibration performance.
• Net weight of 10 kg (dual-rail); can be operated by a single person. Maximum measurement speed up to 10 km/h.
• Proprietary four-line synchronous measurement of the rail head, capturing both lateral and longitudinal corrugation distribution.
• Used for evaluating rail corrugation and weld condition, and assessing maintenance effectiveness.
• Utilizes Class 00 granite calibration platform for sensor accuracy verification and measurement precision calibration.
• Non-contact measurement capable of detecting short-wavelength rail geometry through weld joints.
• Equipped with a "One-Click Report" function, allowing customizable report templates to provide localized and convenient functional services.

Processing Software

The post-processing software of the CRM series rail corrugation measurement instrument can be used together with the measurement software for device control during the measurement phase, as well as for data analysis, post-processing, and report generation after measurement is completed.

Report Generation

• The post-processing software includes a "One-Click Report" function, which automatically generates professional analysis reports.
• The One-Click Report can generate customized templates based on user requirements or use professional templates organized by content.
• Report analysis includes indicators such as RMS, P-P value, and one-third octave frequency evaluation.

Calibration Equipment and Certificat

• A 4-meter Class 00 granite calibration platform is used as the reference. Metrological certification confirms that within a 3-meter range, the repeatability is 4.4 μm and the absolute accuracy is 0.01 mm/m.

Test Results

• High-Speed Rail Short-Wavelength Geometry Precision Measurement.
