The RB 401 DILPATS-RH appears to belong to a class of thermal / dilatometry equipment aimed at characterizing materials’ dimensional changes under temperature. The name “DILPATS” suggests dilatometry / “dil” and “PATS” (possibly “pat / path / pattern”) while the suffix “-RH” might indicate a specific configuration (e.g. “R” for reference, “H” for high temperature, or “RH” for relative humidity option).

This instrument may combine a heating chamber, thermally controlled environment, and displacement sensors to track how material samples expand, contract, or deform with temperature changes. It would be useful in materials science, metallurgy, ceramics, composites, or polymers to assess thermal expansion coefficients, phase transitions, stress/strain under thermal loading, and dimensional stability.

Equipped with accurate temperature control, displacement measurement (micrometer, LVDT, optical sensor), and perhaps environmental control (humidity), the DILPATS-RH unit allows controlled thermal cycling tests with real-time measurement of dimensional changes. Integrated control and data acquisition electronics would allow logging, analysis, and automation of thermal profiles.

This machine complements R&B’s portfolio in material and sample characterization, enabling labs to conduct thermal property tests in support of metallurgy, materials engineering, and failure analysis.
