The Dillon X-C Mechanical Force Gauge with Hardened Ball is available in nine capacities from 50 lb to 25,000 lb or 50 kg to 10,000 kg. Accuracy is ±1% of full range. 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. Proven accuracy and ruggedness sets our Dillon X-C Mechanical Force Gauge with Hardened Ball apart in the force measurement industry. The "D" shaped deflection beam is the heart of the X-C. Highly engineered materials with close machining tolerances and proper heat treatment provide optimum strength and spring characteristics. Calibration is available in pounds or kilograms.
