Title: Manually operated hardness tester - with total and reference force helical springs designed to avoid spring misalignment errors
Inventor: ERNST ALFRED
IPC: G01N3/44
Filed: 1976-03-09
Abstract: A manually operated hardness tester with a reference force and total force action is designed to avoid measurement errors due to eccentric alignment w.r.t. the axis of the helical springs. Such testers are arranged with two springs such that the pressure on a reference ring is the difference between the press. on an internal flange and that on the hardness probe. The forces on the reference ring and on the hardness probe are provided by separate helical springs which operate independently but are compressed by a common member. The operating member is a housing with arms for manual press. exertion and with buffers to limit its travel. The test load varies negligibly with different axial operating positions of the probe owing to the spring characteristic.
