Dillon Mechanic Force Gauges
A D-shaped deflection beam is the?heart of the Dillon force gauges.?Machined to close tolerances, beams?are heat treated to develop optimum?strength and spring characteristics.?High-strength aluminum is used in?Model X instruments through 500?lb (200 kg). Ranges above this are?fabricated from aircraft-quality?alloy steel.?A precision dial indicator is mounted?at the null point of the deflection?beam. The indicator plunger rests?against a slanted anvil at the open?end of the beam. Under compression loads,?the two halves of the beam tend to?close. Tension force causes them to?move apart. This action pushes the?plunger inward, as determined by?the slant of the anvil. Readings?produced on the dial are in direct?relation to applied load. The pointer?revolves 360? clockwise under?compression or tension forces.?Push-pull gauges read half scale?(180?) clockwise in compression, and?counterclockwise, 180? from center?zero under tension loads.
