Solartron DP1S used in Newage Hardness Tester
Product News Thursday, October 25, 2012: Ametek Solartron Metrology
Newage Testing Instruments has solved a difficult metrology problem with the help of Solartron’s DP1S digital LVDT.
The Rockwell hardness test for metal measures the depth of penetration of a conical diamond under loads up to 150 kg. At 150 kg. maximum penetration (0 hardness) is 200 microns. Reducing the load to 1 kg. reduces maximum penetration to about 20 microns.
In order to obtain 0.1% accuracy, the depth of penetration must be measured to 20 nanometers.
“No problem, the Solartron DP1S has an incredible 18 bit A/D giving a LSB of about 4 nanometers. The beauty of it is that the DP1S performs to its specification, completely eliminating the difficult measuring problem from the design process.”
