CISAM-Ernst HTD30 / HTD1500 / HTD4000 – non-destructive case hardening depth (CHD) analyzers
Applications
For determining the depth of the hardened (carburised) layer without cutting, mounting and polishing the part – the part remains intact, so the entire production batch can be inspected. A single indentation with progressively increasing load records a load–penetration curve, which is analysed by the patented Ernst algorithm; a single test takes about 1 minute. HTD30 is designed for thin layers (0.02–0.2 mm), HTD1500 / HTD4000 for deep layers (up to 1.3 / 2.7 mm).
Key features
- Non-destructive measurement – the sample remains intact, 100 % batch inspection is possible
- Result in ~1 min instead of several hours of metallographic preparation
- Direct CHD reading, schematic hardness curve, statistics and curve overlay
- One indentation is equivalent to many indentations at one point (manufacturer’s claim)
- HTD1500/4000: rigid frame for large parts, carbide indenter lasts 2,500–3,000 tests
- USB and Ethernet interfaces; languages: Italian, English, German
