Crack Depth Meter

Product catalog summary

Overview: The RMG 4015 is a crack depth gauge utilizing sensor and microprocessor technology from Germany. It is designed for reliable crack depth measurement and data storage, suitable for fine cracks and fatigue fractures with easy operation.

Key Features:

Extended Applicability: Features a multiple point material correction function, making it applicable for inclined cracks with a special probe to determine angle and depth.
Lightweight Design: Weighs 265g, making it portable and easy to handle.
Adaptability: Optimized for steel, iron, and austenitic steels, with a special version available for other conductive materials like copper and aluminum.

Measurement Technique:

Uses the AC electrical potential drop method, which is largely independent of workpiece geometry due to the skin effect.
Calibration is performed using an artificial crack or crack-free surface, with the ability to store reference cracks for improved accuracy.

Technical Specifications:

Dimensions: 83 x 151 x 35 mm
Power Supply: 2 x 1.5 V AA batteries or rechargeable alternatives
Operating Time: At least 11.5 hours with alkaline batteries
Data Storage: Can store approximately 3850 values across 300 batches, with statistical evaluations available.
Measuring Range: 0 to 99.9 mm
Measurement Accuracy: Varies by material, typically 1 to 15% for ferromagnetic materials and 1 to 25% for austenitic materials.
Operating Conditions: 0°C to 45°C for operation, -20°C to +60°C for storage without batteries.

Probes and Accessories:

Includes various probes for different applications, such as RMSQ for high resolution and RMSL for hard-to-reach areas.
Accessories include control blocks, chargers, matrix printers, and software for data transfer.

Applications: Suitable for production testing to determine if further machining is possible and for monitoring crack growth in machinery to optimize repair timing.
