Fastener Testing

Buehler – ITW Test & Measurement GmbH states that its new Wilson RH2150 represents the next generation of hardness testers.

Based on the concept of the proven globally used RB2000, and offering a large range of testing scales and newly developed functions, Buehler points out that the RH2150 meets today’s testing requirements. Due to its numerous accessories, it is also capable of testing many different parts and components – whether in high volume production applications, in quality control or in the R&D laboratory.

With its completely new user interface and advanced statistical calculations, as well as results graphing and easy test programmability, the Wilson RH2150 optimises testing processes. Via an integrated USB interface, results can be exported as a csv and/or txt file on a memory device. The optional, individually configurable DiaMet™ test software – with its further advanced programming and export functions – provides for additional flexibility.

The new Wilson RH2150 series is available in two configurations for different load ranges. Whereas the Regular version is appropriate for the regular Rockwell scale, the Twin version also allows measuring in the superficial Rockwell scale. In addition, both can be used for Brinell depth testing with up to 187.5kgf and for ball indentation testing that is common in the plastics and the carbon industry. The maximum specimen heights are 10 inches (254mm) with size 1 and 14 inch (356mm) with size 2 of the tester. The maximum specimen weight is 50kg (centred on anvil).

A number of special features provide for easy working without compromising on safety and efficiency. These include the innovative clamping device that fixes the part securely on the tester and provides stability during testing; the adjustable LED for optimum workspace illumination; indenter extensions for testing on more complex shapes; as well as rigid control buttons for automatic test head movement and test initiation. With the design and manufacturing of the RH2150 tester, the DiaMet software, and test blocks, all done in-house by Buehler, system integration is guaranteed.

“The trend towards ever tighter manufacturing tolerances and more advanced heat treatment methods – in the automotive and aerospace industries – require hardness testing systems to be durable while maintaining precise control during critical test data generation,” explains Matthias Pascher, hardness product manager at Buehler. “They must be easy to use, yet flexible enough to meet the increasing demands in these industries. The new Wilson RH2150 meets these demands. This reliable and easy to use system offers superior accuracy and repeatability against low training requirements. The DiaMet software package enables the system to be controlled via the user interface, with automatic reporting and full traceability of test results possible – thanks to the integrated DiaMet database.”
