Dillon X-PP Tension And Compression Force Gauge

The X-PP Force gauges calibrated in push-pull are available in four capacities in pounds ranging from 50 lb up to and including 2,500-0-2,500 lb and three metric capacities from 50 to 1,000 kg. Accuracy is ±2% of maximum dial reading (based upon total capacity of both compression and tension scales).

Model X-PP gauges in capacities up to and including 500 lb or 250 kg are supplied with a set of self-aligning spherical rod-end connectors for tension loading. Force is applied to connectors through a hardened steel pin which must be slip fit in connector holes.

2,500 lb and 1,000 kg capacity gauges are equipped with two shackle adapters, shackles and pins. Shackles must be removed when compression load is involved. Force is then applied against shackle pins in a suitable test setup.

All push-pull gauges are supplied with a compression-loading spherical ball fitting for compression loading.

Principle of Operation

A D-shaped deflection beam is the heart of the Dillon Force Gauge. 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, as shown in the photo. 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.

Options

Shockless dial indicator for installations involving the sudden application or release of force. (Maximum pointer cannot be supplied with shockless dial indicator)

Maximum load pointer which remains at peak load until manually reset.

Zero position on dial may be factory positioned at 12, 3, 6, or 9 o'clock. Standard position is at 12 o'clock.
