✦ Synopsis
output voltage, which is proportional to force, is amplified, scaled, and displayed on a digital voltmeter calibrated directly in kilograms. The display on the digital panel meter is held a t the maximum force value by utilizing the tablet breakage point sensing circuitry in the hardness tester.
Calibration and linearity of the digital readings can be checked by displacing the anvil on the hardness tester in small increments while noting the reading on the meter incorporated in the hardness tester. Magnet placement, Hall device power supply voltage, and scaling amplifiers are adjusted for the proper reading.
A method for calibrating the hardness tester was mentioned previously (2).
Advantages of the digital approach include: (a) accuracy, (b) low cost of the transducer and system, (c) ease of construction, (d) no change in operating procedures, (e) automatic printout if desired, and (f) hardness tester not affected by operation of the transducer.
