Accredited ISO 17025 calibration certificate for these X-ST Force Gauge with "D" shaped deflection beam force tools is be available on request (for an extra charge). Why Calibrate?


Proven accuracy and ruggedness sets our mechanical force gauge apart in the force measurement industry. The "D" shaped deflection beam is the heart of the Force Gauge system. Highly engineered materials with close machining tolerances and proper heat treatment provide optimum strength and spring characteristics. Two year warranty.


  • ±1% accuracy
  • Shockless dial indicator
  • Used in horizontal, verticle or flat position
  • Two year warranty

Model X-ST with tension calibration

Dillon offers the Model X-ST in seven capacities from 100 lb to 10,000 lb or 25 kg to 5000 kg. Accuracy is ±1% of full range. (Note: For applications requiring capacities beyond 10,000 lb or 5000 kg in tension, consider the Dillon Dynamometer). Tension Force Gauges in capacities through 2,000 lb (1000 kg) are supplied with two rod-end connectors. 5,000 and 10,000 lb (5000 kg) capacities are equipped with convenient shackles and pins. Calibration is available in pounds, kilograms or Newtons.

Load is applied against a hardened ball which rotates to maintain vertical alignment as pressure increases. The ball is held in place with a spring clip or retainer. A threaded mounting hole is located opposite the loading ball in the bottom of the beam. Model X-C is available in pound, kilogram or Newton capacities.

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.

Overload rating

Accidental overloads up to 30% of capacity can be safely sustained without injury to the dial indicator or deflection beam. All capacities feature a 5:1 design safety factor.

Low beam deflection

When measured across the center of top- and bottom-loading holes, the approximate beam deflection is as follows:

  • 50 to 250-lb (25 to 100 kg) capacity: 0.019"
  • 500-lb (200 kg) capacity: 0.016"
  • 1,000-lb (500 kg) capacity: 0.018"
  • 2,000-lb (1000 kg) capacity: 0.011"
  • 5- and 10,000-lb (2 and 5000 kg) capacity: 0.010"
  • 25,000-lb (10,000 kg) capacity 0.022"

  • 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. (not available on Model X-PP)
  • Zero position on dial may be factory positioned at 12, 3, 6, or 9 o'clock. Standard position is at 12 o'clock is your fast, easy-to-use website for quality force instruments available for almost any industries to measure the force during a push or pull test. We offer over 500 force gages and force sensors from most valuable brands, ready to be shipped from our Brampton (Toronto area) warehouse.
